Chapter 1: Product description Important regulatory information Page 3 Important regulatory information The PMP/PTP 450i and 450 products are certified as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands). Application firmware Download the latest PMP/PTP 450(i) Series firmware and install it in the Outdoor Units (ODUs) before deploying the PMP/PTP 450(i) Series equipment. Instructions for installing firmware are provided in Error! Reference source not found. on page Error! Bookmark not defined.. USA specific information Caution This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: • This device may not cause harmful interference, and • This device must accept any interference received, including interference that may cause undesired operation The USA Federal Communications Commission (FCC) requires manufacturers to implement special features to prevent interference to weather radar systems that operate in the band 5600 MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in the band 5470 MHz to 5725 MHz. Manufacturers must ensure that such radio products cannot be configured to operate outside of FCC rules; specifically it must not be possible to disable or modify the radar protection functions that have been demonstrated to the FCC. In order to comply with these FCC requirements, Cambium supplies variants of the PMP/PTP 450(i) for operation in the USA. These variants are only allowed to operate with license keys that comply with FCC rules. To ensure compliance with FCC rules (KDB 905462 D04 Operational Modes for DFS Testing New Rules v01), follow the recommendation in Avoidance of weather radars (USA only).

Chapter 1: Product description Important regulatory information Page 4 External antennas When using a connectorized version of the product, the conducted transmit power may need to be reduced to ensure the regulatory limit on transmitter EIRP is not exceeded. The installer must have an understanding of how to compute the effective antenna gain from the actual antenna gain and the feeder cable losses. The range of permissible values for maximum antenna gain and feeder cable losses are included in this user guide together with a sample calculation. The product GUI automatically applies the correct conducted power limit to ensure that it is not possible for the installation to exceed the EIRP limit, when the appropriate values for antenna gain and feeder cable losses are entered into the GUI. Avoidance of weather radars (USA only) To comply with FCC rules (KDB 443999: Interim Plans to Approve UNII Devices Operating in the 5470 - 5725 MHz Band with Radar Detection and DFS Capabilities), units which are installed within 35 km (22 miles) of a Terminal Doppler Weather Radar (TDWR) system (or have a line of sight propagation path to such a system) must be configured to avoid any frequency within +30 MHz or –30 MHz of the frequency of the TDWR device. This requirement applies even if the master is outside the 35 km (22 miles) radius but communicates with outdoor clients which may be within the 35 km (22 miles) radius of the TDWRs. If interference is not eliminated, a distance limitation based on line-of-sight from TDWR will need to be used. Devices with bandwidths greater than 20 MHz may require greater frequency separation. When planning a link in the USA, visit http://spectrumbridge.com/udia/home.aspx, enter the location of the planned link and search for TDWR radars. If a TDWR system is located within 35 km (22 miles) or has line of sight propagation to the PTP device, perform the following tasks: • Register the installation on http://spectrumbridge.com/udia/home.aspx. • Make a list of channel center frequencies that must be barred, that is, those falling within +30 MHz or –30 MHz of the frequency of the TDWR radars. The PMP 450(i) AP must be configured to not operate on the affected channels. Canada specific information Caution This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device. Industry Canada requires manufacturers to implement special features to prevent interference to weather radar systems that operate in the band 5600 MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in the band 5470 MHz to 5725 MHz.

Chapter 1: Product description Important regulatory information Page 5 Manufacturers must ensure that such radio products cannot be configured to operate outside of IC rules; specifically it must not be possible to disable or modify the radar protection functions that have been demonstrated to IC. In order to comply with these IC requirements, Cambium supplies variants of the PMP/PTP 450(i) for operation in Canada. These variants are only allowed to operate with license keys that comply with IC rules. In particular, operation of radio channels overlapping the band 5600 MHz to 5650 MHz is not allowed and these channels are permanently barred. In addition, other channels may also need to be barred when operating close to weather radar installations. Other variants of the PMP/PTP 450(i) are available for use in the rest of the world, but these variants are not supplied to Canada except under strict controls, when they are needed for export and deployment outside Canada. Renseignements specifiques au Canada Attention Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Industry Canada (IC) a demandé aux fabricants de mettre en œuvre des mécanismes spécifiques pour éviter d’interférer avec des systèmes radar fonctionnant dans la bande 5600 MHz à 5650 MHz. Ces mécanismes doivent être mis en œuvre dans tous les produits capables de fonctionner à l'extérieur dans la bande 5470 MHz à 5725 MHz. Les fabricants doivent s'assurer que les produits de radiocommunications ne peuvent pas être configurés pour fonctionner en dehors des règles IC, en particulier, il ne doit pas être possible de désactiver ou modifier les fonctions de protection des radars qui ont été démontrés à IC. Afin de se conformer à ces exigences de IC, Cambium fournit des variantes du PMP/PTP 450(i) exclusivement pour le Canada. Ces variantes ne permettent pas à l’équipement de fonctionner en dehors des règles de IC. En particulier, le fonctionnement des canaux de radio qui chevauchent la bande 5600-5650 MHz est interdite et ces canaux sont définitivement exclus.

Chapter 1: Product description Wireless operation Page 1-12 Wireless operation This section describes how the PMP/PTP 450(i) Series wireless link is operated, including modulation modes, power control and security. Time division duplexing The system uses Time Division Duplexing (TDD) – one channel alternately transmits and receives rather than using one channel for transmitting and a second channel for receiving. To accomplish TDD, the AP/BHM must provide sync to its BHS. Furthermore, collocated APs/BHMs must be synced together – an unsynchronized AP/BHM that transmits during the receive cycle of a collocated AP/BHM can prevent a second AP/BHM from being able to decode the signals from its APs/BHSs. In addition, across a geographical area, APs/BHMs that can “hear” each other benefit from using a common sync to further reduce self-interference within the network. Modules use TDD on a common frequency to divide frames for uplink (orange) and downlink (green) usage, as shown in the figure below. For more information on synchronization configuration options, see GPS synchronization on page 2-37. Figure 2 TDD frame division Time

Chapter 1: Product description Wireless operation Page 1-13 TDD frame parameters The TDD burst duration varies depending on the following: • Channel Bandwidth • Cyclic Prefix • Frame Period • Frame configuration - Downlink Data • Link operation – Dynamic Rate Adaptation OFDM and channel bandwidth The PMP/PTP 450(i) series transmits using Orthogonal Frequency Division Multiplexing (OFDM). This wideband signal consists of many equally spaced sub-carriers. Although each sub carrier is modulated at a low rate using conventional modulation schemes, the resultant data rate from the sub-carriers is high. OFDM works exceptionally over a Non-Line-of-Sight (NLoS) channel. The channel bandwidth of the OFDM signal is configurable to one of the following values: 5, 10 and 20 MHz. Higher bandwidths provide greater link capacity at the expense of using more bandwidth. Systems configured for a narrower channel bandwidth provide better receiver sensitivity and can also be an appropriate choice in deployments where the amount of free spectrum is limited. Note The Channel Bandwidth must be configured to the same value at both ends of the link. Not all channel bandwidths are available in all regulatory bands. Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol (slot) to allow multi-pathing to settle before receiving the desired data. A 1/16 cyclic prefix means that for every 16 bits of throughput data transmitted, an additional bit is used. Frame Period The frame period or frame duration is the time between the beginning of a frame and the end of the frame. The PMP/PTP 450(i) Series supports two frame periods: 2.5 ms and 5 ms. The 5ms frame period configuration provides higher throughput as a result of reduced frame overhead during transmission. In turn, the 2.5 ms frame period configuration affords reduced latency in the system, half of that introduced by the 5 ms frame configuration.

Chapter 1: Product description Wireless operation Page 1-14 Frame configuration - Downlink Data The percentage of frame assigned to transport downlink data. The downlink data specifies the percentage of the aggregate throughput for the downlink (frames transmitted from the AP/BHM to the subscriber). The configurable range is 15 to 85 percent. Link operation – Dynamic Rate Adapt PMP/PTP 450(i) Series products offer eight levels or speeds of operation – 2X MIMO-B and 1X MIMO-A (QPSK), 4X MIMO-B and 2X MIMO-A (16-QAM), 6x MIMO-B and 3X MIMO-A (64-QAM) and 8X MIMO-B and 4X MIMO-A (265-QAM). If received power is less due to distance between the AP/BHM and the SM/BHS or due to obstructions, or if interference affects the RF environment, the system automatically and dynamically adjusts the links to the best operation level. The system chooses its modulation rate dynamically, based on an internal ARQ (Automatic Repeat reQuest) error control method. With ARQ, every data slot of every frame sent over the air (except downlink broadcast) is expected to be acknowledged by the receiver, and if acknowledgement is not received, the data is resent. The sending unit monitors these re-sends and adjusts the modulation rate accordingly. It is normal to have links that change levels of operation as the RF environment changes. Furthermore, the uplink or downlink portions of TDD duty cycle operate independently; normal operation can have a downlink running at 6x while the uplink RF environment only supports 2x. The various modulation levels used by the PMP/PTP 450(i) are shown in Table 7. Table 7 Modulation levels Rate MIMO-B MIMO-A QPSK 2X MIMO-B 1X MIMO-A 16-QAM 4X MIMO-B 2X MIMO-A 64-QAM 6X MIMO-B 3X MIMO-A 256-QAM 8X MIMO-B 4X MIMO-A Note MIMO-A achieves half the throughput of MIMO-B but adds a combining diversity (gain) which enhances the link budget or availability.

Chapter 1: Product description Wireless operation Page 1-15 MIMO Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading and increase the probability that the receiver decodes a usable signal. When the effects of MIMO are combined with those of OFDM techniques and a high link budget, there is a high probability of a robust connection over a non-line-of-sight path. The sub-features that comprises the MIMO techniques utilized in the PMP/PTP 450(i) product are: • Matrix A: This technique enables the PMP/PTP 450(i) radio to use a scheme that optimizes coverage by transmitting the same data over both antennas. This redundancy improves the signal to noise ratio at the receiver making it more robust, at the cost of throughput. • Matrix B: This technique provides for the ability to double the throughput of a radio transmission under proper RF conditions. Different data streams are transmitted simultaneously on two different antennas. Encryption The Cambium PMP/PTP 450(i) Series supports optional encryption for data transmitted over the wireless link. The PTP 450(i) Series supports the following forms of encryption for security of the wireless link: • DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system. • AES (Advanced Encryption Standard): An over-the-air link encryption option that uses the Rijndael algorithm and 128-bit keys and 256-bit key size to establish a higher level of security than DES. AES products are certified as compliant with the Federal Information Processing Standards (FIPS 197) in the U.S.A.

Chapter 1: Product description System management Page 1-16 System management This section introduces the PMP/PTP 450(i) management system, including the web interface, installation, configuration, alerts and upgrades. Management agent PMP/PTP 450(i) Series equipment is managed through an embedded management agent. Management workstations, network management systems or PCs can be connected to this agent using the module’s Ethernet port or over-the air (SM/BHS) The management agent supports the following interfaces: • Hypertext transfer protocol (HTTP) • Hypertext transfer protocol secure (HTTPS) • RADIUS authentication • Simple network management protocol (SNMP) – v2c and v3 • Network time protocol (NTP) • System logging (Syslog) • Wireless Manager (WM) software • Canopy Network Updater Tool (CNUT) software Web server The PMP/PTP 450(i) management agent contains a web server. The web server supports access via the HTTP/HTTPS interface. Web-based management offers a convenient way to manage the PMP/PTP 450(i) equipment from a locally connected computer or from a network management workstation connected through a management network, without requiring any special management software. The web and SNMP are the interfaces supported for installation of PMP/PTP 450(i) and for the majority of PMP/PTP 450(i) configuration management tasks.

Chapter 1: Product description System management Page 1-17 Web pages The web-based management interfaces provide comprehensive web-based fault, configuration, performance and security management functions organized into the following groups: Access Point or Backhaul Master: • Home • Configuration • Statistics • Tools • Logs • Accounts • Quick Start • Copyright Subscriber Module or Backhaul Slave • Home • Configuration • Statistics • Tools • Logs • Accounts • PDA • Copyright Identity-based user accounts • When identity-based user accounts are configured, a security officer can define from one to four user accounts, each of which may have one of the four possible roles: • ADMINISTRATOR, who has full read and write permissions. This is the level of the root and admin users, as well as any other administrator accounts that one of them creates. • INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the installer cannot add or delete users or change the password of any other user. • TECHNICIAN, who has permissions to modify basic radio parameters and view informational web pages • GUEST, who has no write permissions and only a limited view of General Status tab • Admin, Installer and Tech accounts can be configured as READ-ONLY. This will allow the account to only see the items. See Managing module access by passwords for detailed information on account permissions.

Chapter 1: Product description System management Page 1-18 Remote Authentication Dial-in User Service (RADIUS) The PMP 450(i) system includes support for RADIUS (Remote Authentication Dial In User Service) protocol functionality including: • Authentication: Allows only known SMs onto the network (blocking “rogue” SMs), and can be configured to ensure SMs are connecting to a known network (preventing SMs from connecting to “rogue” APs). RADIUS authentication is used for SMs, but not used for APs. • SM Configuration: Configures authenticated SMs with MIR (Maximum Information Rate), High Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when a SM registers to an AP. • SM Accounting provides support for RADIUS accounting messages for usage-based billing. This accounting includes indications for subscriber session establishment, subscriber session disconnection, and bandwidth usage per session for each SM that connects to the AP. • Centralized AP and SM user name and password management: Allows AP and SM usernames and access levels (Administrator, Installer, Technician and Read-Only) to be centrally administered in the RADIUS server instead of on each radio and tracks access events (logon/logoff) for each username on the RADIUS server. This accounting does not track and report specific configuration actions performed on radios or pull statistics such as bit counts from the radios. Such functions require an Element Management System (EMS) such as Cambium Wireless Manager. This accounting is not the ability to perform accounting functions on the subscriber/end user/customer account. • Framed-IP-Address: Operators may use a RADIUS server to assign management IP addressing to SM modules. SNMP The management agent supports fault and performance management by means of an SNMP interface. The management agent is compatible with SNMP v2c and SNMP v3 using Management Information Base (MIB) files which are available for download from the Cambium Networks Support website: https://support.cambiumnetworks.com/files/ptp450 https://support.cambiumnetworks.com/files/pmp450 Network Time Protocol (NTP) The clock supplies accurate date and time information to the system. It can be set to run with or without a connection to a network time server (NTP). It can be configured to display local time by setting the time zone and daylight saving in the Time web page. If an NTP server connection is available, the clock can be set to synchronize with the server time at regular intervals. PMP/PTP 450(i) devices may receive NTP data from a CMM4 module or an NTP server configured in the system’s management network.

Chapter 1: Product description System management Page 1-19 The Time Zone option is configurable on the AP’s/BHM’s Time Configuration page, and may be used to offset the received NTP time to match the operator’s local time zone. When set on the AP/BHM, the offset is set for the entire sector (AP/BHSs is notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the AP/BHSs are notified of the change in a best effort fashion, meaning some AP/BHSs may not pick up the change until the next re-registration. Time Zone changes are noted in the Event Log. An AP/BHM which is receiving NTP date and time information from an NTP server or from a GPS synchronization source may be used as an NTP server. Any client which has IP connectivity to the BHM may request NTP date and time information from the AP/BHM. No additional configuration (other than the AP/BHM receiving valid NTP data) is required to use the AP/BHM as an NTP server.

Chapter 1: Product description System management Page 1-20 Canopy Network Updater Tool (CNUT) CNUT (Canopy Network Updater Tool) is the stand-alone software update tool for PMP/PTP 450(i) Series products. The CNUT 4.9.12 or greater should be used for 450(i) radios. The Canopy Network Updater Tool has the following features: • Automatically discovers all network elements • HTTP and HTTPS • Executes UDP command that initiates and terminates the Auto-update mode within APs/BHMs. This command is both secure and convenient: o For security, the AP/BHM accepts this command from only the IP address that specified in the Configuration page of ODU. o For convenience, Network Updater automatically sets this Configuration parameter in the AP/BHM to the IP address of the Network Updater server when the server performs any of the update commands. • Allows you to choose among updating: o Entire network. o Only elements that you select. o Only network branches that you select. • Provides a Script Engine that you can use with any script which: o The user can define. o Cambium supplies. CNUT is available at: http://www.cambiumnetworks.com/support/management-tools/cnut/ Radio recovery mode – Radio Recovery Console / Default Mode (fka Default Plug) PMP/PTP 450i The PMP/PTP 450i recovery mode provides a means to recover from serious configuration errors including lost or forgotten passwords and unknown IP addresses. Recovery mode also allows new main application software to be loaded even when the integrity of the existing main application software image has been compromised. The most likely cause of an integrity problem with the installed main application software is where the power supply has been interrupted during a software upgrade. The recovery mode supports a single IPv4 interface, with IP address 169.254.1.1, and with default link settings. Note When Recovery has been entered through a power on/off/on cycle, the ODU will revert to normal operation if no web access has been made to the unit within 30 seconds.

Chapter 1: Product description System management Page 1-21 This prevents the unit remaining inadvertently in recovery following a power outage. Recovery mode options Options in recovery mode (IPv4 only) are as follows: • Load a previous SW image • Boot with default Canopy system software settings (similar to the hardware default plug on previous Canopy-based PMP platforms) The last most recent software image loaded to the board is retained. The factory image is not retained. Boot with default Canopy system software settings (similar to the hardware default plug on previous Canopy-based PMP platforms). See Error! Reference source not found. on page Error! Bookmark not defined.. PMP/PTP 450 A default plug (sometimes called an override plug) is available to provide access to a module whose password and/or IP address have been forgotten. This plug allows the PMP 450 AP, PMP 450 SM, or PTP 450 BH to be accessed using IP address 169.254.1.1 and no password. During the override session, you can assign any new IP address and set either or both user passwords (display-only and/or full access) as well as make other parameter changes. This plug is available from Best-Tronics Manufacturing, Inc. See http://www.best-tronics.com/cambium.htm as Part BT-0583 (RJ-11 Default Plug). Alternatively, you can fabricate an override plug.

Figure 3 Radio diagnostic LEDs, viewed from unit front ODU LED Display LED Labels LNK/5 ACT/4 GPS/3 SES/2 SYN/1 PWR Note The LED color helps distinguish the position of LED. The LED color does not indicate any status. AP/BHM LEDs The diagnostic LEDs report the information about the status of the BHM/AP.

Note The LED color helps you distinguish position of the LED. The LED color does not indicate any status. SM/BHS LEDs The SM/BHS LEDs provide different status of radio based on the operating modes. A SM/BHS in “operating” mode registers and passes traffic normally. A SM/BHS in “aiming” mode does not register or pass the traffic, but displays (via LED panel) the strength of received radio signals (based on radio channel selected via Tools -> Alignment).

SYN/1 Yellow Presence of sync These five LEDs act as a bar graph to indicate the relative quality of alignment. As power level improves during alignment, more of these LEDs are lit. Lit when SM/BHS is in sync with an AP/BHM. SES/2 Green Session Indicator Lit when SM/BHS is in session. GPS/3 Red Unused On - high interference. Blinking - medium interference. Off - low interference. ACT/4 Yellow Presence of data activity on the Ethernet link Flashes during data transfer. Frequency of flash is not a diagnostic indication.

Operating Mode • Scanning: If the SM/BHS is not registered to AP/BHM, then these three LEDs cycle on and off from left to right (SYN/1, SES/2 and GPS/3). • Ethernet Link: The LNK/5 LED lit continuously when link is present. • Data Transfer: The ACT/4 LED lit on the presence of data activity on the Ethernet link.

Chapter 2: System hardware System Components Page 2-14 Aiming Mode The 5 LEDs (SYN/1, SES/2, GPS/3, ACT/4 and LNK/5) are turned into a 5-position bar graph. The more LEDs that are lit, the better the received power the module is seeing. The colors of the LEDS have no particular meaning other than to assist is distinguishing one position from the next.

Chapter 2: System hardware Cabling and lightning protection Page 2-29 Outdoor copper Cat5e Ethernet cable Outdoor Cat5e cable is used for all connections that terminate outside the building. For example, connections between the ODU, surge suppressors (if installed), UGPS receivers (if installed) and the power supply injector. This is known as a “drop cable” (Figure 9). The following practices are essential to the reliability and longevity of cabled connections: • Use only shielded cables and connectors to resist interference and corrosion. • For vertical runs, provide cable support and strain relief. • Include a 2 ft (0.6 m) service loop on each end of the cable to allow for thermal expansion and contraction and to facilitate terminating the cable again when needed. • Include a drip loop to shed water so that most of the water does not reach the connector at the device. • Properly crimp all connectors. • Use dielectric grease on all connectors to resist corrosion.

Chapter 2: System hardware Antennas and antenna cabling Page 2-35 RF cable and connectors RF cable of generic type LMR-400 is required for connecting the ODU to the antenna. N type male connectors are required for connecting the RF cables to the connectorized ODU. Two connectors are required per ODU. Use weatherproof connectors, preferably ones that are supplied with adhesive lined heat shrink sleeves that are fitted over the interface between the cable and connector. Order CNT-400 RF cable and N type male connectors from Cambium Networks (Table 41).

Chapter 2: System hardware GPS synchronization Page 2-37 GPS synchronization GPS synchronization description Cambium offers GPS synchronization to limit the network’s own self-interference. The Cluster Management CMM provides Global Positioning System (GPS) synchronization to the Access Point (AP) and all associated Subscriber Modules (SM). Network operators have a choice of UGPS and CMM solutions to select the option that works best for the environment. Universal GPS (UGPS) The UGPS provides network synchronization for smaller networks where a CMM may not be cost effective. The UGPS provides synchronization for one or two modules so that even remote areas at the edge of the network can operate with synchronization for improved performance. The UGPS works with all Cambium PMP radios. The UGPS has a small footprint and is easy to deploy. Figure 13 UGPS CMM4 (Rack Mount) The Cluster Management Module (CMM) is the heart of the Cambium system’s synchronization capability, which allows network operators to reuse frequencies and add capacity while ensuring consistency in the quality of service to customers. For operators who prefer indoor CMM mounting, Cambium offers the Rack-Mounted Cluster Management Module 4. The unit is designed to be mounted onto a standard 19-inch telecommunications rack and to allow the Cambium CMM4 to be co-located with other telecommunications equipment.

Chapter 2: System hardware GPS synchronization Page 2-38 Figure 14 CMM4 (Rack Mount) The CMM4 has two DC power inputs, one 29 V and one 56V. It can be used to power and synchronize both 29V legacy products such as PMP 450 and 56V products such as PMP 450i simultaneously. If the 29V legacy products are connected to the CMM4, a 29V power supply needs to be connected. If PMP/PTP 450(i) are connected to a CMM4, it needs to be connected with an external 56V PSU". The CMM4 supports having two of the 56V and two of the 24V supplies for redundancy. Warning PMP 450 and PMP 450i require different wiring between the CMM4 and device. If a PMP450 is replaced by a PMP 450(i) and the existing drop cable needs to be re-used, the adapter "CMM4 56V power adapter, #N000045L001A" must be used between the CMM4 and the existing drop cable.

Chapter 2: System hardware GPS synchronization Page 2-40 CMM4 (Cabinet with switch) Designed to deliver consistent and reliable wireless broadband service, the PMP/PTP system gracefully scales to support large deployments. The cluster management module is the heart of the system’s synchronization capability which allows network operators to re-use frequencies and add capacity while ensuring consistency in the quality of service to customers. As a result, subscribers can experience carrier-grade service even at the outer edge of the network. Figure 17 CMM4 (Cabinet with switch) CMM4 (Cabinet without switch) This CMM includes all of the functionality listed above but there is no switch. This provides the network operator the flexibility to use the switch of their choice with the power and synchronization capabilities of the CMM4. CMM4/CMMmicro The CMM3 or CMMmicro (Cluster Management Module micro) provides power, GPS timing, and networking connections for an AP cluster. The CMM3 is configurable through a web interface.

Chapter 2: System hardware GPS synchronization Page 2-41 The CMM3 contains an 8-port managed switch that supports Power over Ethernet (PoE) on each port and connects any combination of APs, BHMs, BHSs, or Ethernet feed. The Cambium fixed wireless broadband IP networks PoE differs from IEEE Standard 803.3af PoE, and the two should not be intermixed. The CMM3 can auto-negotiate speed to match inputs that are either 100Base-TX or 10Base-T, and either full duplex or half duplex, where the connected device is set to auto-negotiate. Alternatively, these parameters are settable. A CMM3 requires only one cable, terminating in an RJ-45 connector, for each connected module to distribute • Ethernet signaling. • power to as many as 8 co-located modules—APs, BHMs, or BHSs. Through a browser interface to the managed switch, ports can be powered or not. • sync to APs and BHMs. The CMM3 receives 1-pulse per second timing information from Global Positioning System (GPS) satellites through an antenna (included) and passes the timing pulse embedded in the 24-V power to the connected modules. GPS status information is available at the CMM3, however • CMM3 provides time and date information to BHMs and APs if both the CMMmicro is operating on CMMmicro Release 2.1 or later and the AP/BHM is operating on System Release 4.2 or later. See Error! Reference source not found. on Page Error! Bookmark not defined.. • CMM3 does not provide time and date information to BHMs and APs if either the CMM3 is operating on a release earlier than CMMmicro Release 2.1 or the AP/BHM is operating on a release earlier than System Release 4.2.

Chapter 3: System planning Typical deployment Page 3-2 Typical deployment This section contains diagrams illustrating typical PMP/PTP 450(i) site deployments. ODU with PoE interface to PSU In the basic configuration, there is only one Ethernet interface, a copper Cat5e power over Ethernet (POE) from the PSU to the ODU (PSU port), as shown in the following diagrams: mast or tower installation (Figure 20 ), wall installation (Figure 21) and roof installation (Figure 22).

Chapter 3: System planning Site planning Page 3-7 Site planning This section describes factors to be considered when choosing sites for PMP or PTP radios, power supplies, CMM4 (if applicable) and UGPS (if applicable). Site selection for PMP/PTP radios When selecting a site for the ODU, consider the following factors: • Height and location to ensure that people are kept away from the antenna; see Calculated distances and power compliance margins on page 4-24. • Height and location to achieve the best radio path. • Indoor location where power supply LED indicators accessible and cable length should not exceed maximum recommended length; see Power supply site selection • Ability to meet the requirements specified in Grounding and lightning protection on page 3-8. • Aesthetics and planning permission issues. • Cable lengths; see ODU interfaces on page 2-26. • The effect of strong winds on the installation; see ODU wind loading on page 3-11. Calculated distances and power compliance margin The calculated minimum separation distances, recommended distances and resulting margins for each frequency band and antenna combination. These are conservative distances that include compliance margins. At these and greater separation distances, the power density from the RF field is below generally accepted limits for the general population. PMP/PTP 450(i) equipment adheres to all applicable EIRP limits for transmit power when operating in MIMO mode. Separation distances and compliance margins include compensation for both transmitters.

Chapter 3: System planning Site planning Page 3-8 Power supply site selection When selecting a site for the ODU power supply, consider the following factors: • Indoor location with no possibility of condensation, flooding or rising damp. • Availability of a mains electricity supply. • Located in an environment where it is not likely to exceed its operational temperature rating, allowing for natural convection cooling. • Accessibility for viewing status indicator LED and connecting Ethernet cables. • Cable lengths; see ODU interfaces on page 2-26. Maximum cable lengths When installing PMP/PTP 450i Series ODU, the maximum permitted length of the shielded copper Ethernet interface cable is 330 feet (100m) from AP/BHM/SM/BHS to their associated power supplies or CMM4. Grounding and lightning protection Warning Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this guide, when followed correctly, give the user the best protection from the harmful effects of EMD. However 100% protection is neither implied nor possible. Structures, equipment and people must be protected against power surges (typically caused by lightning) by conducting the surge current to ground via a separate preferential solid path. The actual degree of protection required depends on local conditions and applicable local regulations. To adequately protect a PMP/PTP 450(i) installation, both ground bonding and transient voltage surge suppression are required. Full details of lightning protection methods and requirements can be found in the international standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code. Note International and national standards take precedence over the requirements in this guide.

Chapter 3: System planning Site planning Page 3-9 Lightning protection zones Use the rolling sphere method (Figure 25) to determine where it is safe to mount equipment. An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the space under the sphere is considered to be in the zone of protection (Zone B). Similarly, where the sphere rests on two finials, the space under the sphere is considered to be in the zone of protection. Figure 25 Rolling sphere method to determine the lightning protection zones Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in this zone. Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone significantly reduces the possibility of a direct strike. Mount equipment in this zone. Warning Never mount equipment in Zone A. Mounting in Zone A may put equipment, structures and life at risk.

Chapter 3: System planning Site planning Page 3-10 Site grounding system Confirm that the site has a correctly installed grounding system on a common ground ring with access points for grounding PMP/PTP 450(i) equipment. If the outdoor equipment is to be installed on the roof of a high building (Figure 22), confirm that the following additional requirements are met: • A grounding conductor is installed around the roof perimeter to form the main roof perimeter lightning protection ring. • Air terminals are installed along the length of the main roof perimeter lightning protection ring, typically every 6.1m (20ft). • The main roof perimeter lightning protection ring contains at least two down conductors connected to the grounding electrode system. The down conductors should be physically separated from one another, as far as practical. ODU and external antenna location Find a location for the ODU (and external antenna for connectorized units) that meets the following requirements: • The equipment is high enough to achieve the best radio path. • People can be kept a safe distance away from the equipment when it is radiating. The safe separation distances are defined in Calculated distances and power compliance margins on page 4-24. • The equipment is lower than the top of the supporting structure (tower, mast or building) or its lightning air terminal. • If the ODU is connectorized, select a mounting position that gives it maximum protection from the elements, but still allows easy access for connecting and weatherproofing the cables. To minimize cable losses, select a position where the antenna cable lengths can be minimized. If diverse or two external antennas are being deployed, it is not necessary to mount the ODU at the midpoint of the antennas. ODU ambient temperature limits Select a location where the ODU can operate within safe ambient temperature limits. The following points need to be considered while selecting a location for the ODU: • The ODU must be mounted in a Restricted Access Location (as defined in EN 60950-1) if the operating ambient temperature may exceed 40°C, including solar radiation. • If the ambient temperature never exceeds 40°C, the temperature of the external metal case parts of the ODU will not exceed the touch temperature limit of 70°C. • If the ambient temperature never exceeds 60°C, the temperature of the external metal case parts of the ODU will not exceed the touch temperature limit of 90°C.

Chapter 3: System planning Site planning Page 3-11 Note A restricted access location is defined (in EN 60950-1) as one where access may only be gained by use of a tool or lock and key, or other means of security, and access is controlled by the authority responsible for the location. Access must only be gained by persons who have been instructed about the reasons for the restrictions applied to the location and about any precautions that must be taken. Examples of permissible restricted access locations are a lockable equipment room or a lockable cabinet. ODU wind loading Ensure that the ODU and the structure on which it is mounted are capable of withstanding the prevalent wind speeds at a proposed PMP/PTP 450i site. Wind speed statistics are available from national meteorological offices. The ODU and its mounting bracket are capable of withstanding wind speeds of up to 323 kph (200 mph). Wind blowing on the ODU will subject the mounting structure to significant lateral force. The magnitude of the force depends on both wind strength and surface area of the ODU. Wind loading is estimated using the following formulae: • Force (in kilogrammes) = 0.1045aV2 where: o “a” is the surface area in square meters, and o “V” is the wind speed in meters per second. • Force (in pounds) = 0.0042Av2 where: o “A” is the surface area in square feet, and o “v” is the wind speed in miles per hour. Applying these formulae to the PMP/PTP 450i ODU at different wind speeds, the resulting wind loadings are shown in Table 45 and Table 46. Table 45 ODU wind loading (Newton) Type of ODU Max surface area (square meters) Wind speed (kilometer per hour) 160 170 180 190 200 Connectorized 0.035 59 66 74 83 92 Directional 0.093 156 176 197 220 243 90 degree sector 0.126 211 238 267 298 330

The antenna manufacturer should be able to quote wind loading. Drop cable grounding points To estimate how many grounding kits are required for each drop cable, refer to the site installation diagrams (Figure 20 , Figure 21 and Figure 22) and use the following criteria: • The drop cable shield must be grounded near the ODU at the first point of contact between the drop cable and the mast, tower or building. • The drop cable shield must be grounded at the building entry point. For mast or tower installations (Figure 20), use the following additional criteria: • The drop cable shield must be grounded at the bottom of the tower, near the vertical to horizontal transition point. This ground cable must be bonded to the tower or tower ground bus bar (TGB), if installed. • If the tower is greater than 61 m (200 ft) in height, the drop cable shield must be grounded at the tower midpoint, and at additional points as necessary to reduce the distance between ground cables to 61 m (200 ft) or less. • In high lightning-prone geographical areas, the drop cable shield must be grounded at spacing between 15 to 22 m (50 to 75 ft). This is especially important on towers taller than 45 m (150 ft). For roof installations (Figure 22), use the following additional criteria: • The drop cable shield must be bonded to the building grounding system at its top entry point (usually on the roof). • The drop cable shield must be bonded to the building grounding system at the entry point to the equipment room.

Chapter 3: System planning Site planning Page 3-13 LPU location Find a location for the bottom LPU that meets the following requirements: • The bottom LPU can be connected to the drop cable from the ODU. • The bottom LPU is within 600 mm (24 in) of the point at which the drop cable enters the building, enclosure or equipment room within a larger building. • The bottom LPU can be bonded to the grounding system.

Chapter 3: System planning Radio Frequency planning Page 3-14 Radio Frequency planning This section describes how to plan PMP/PTP 450(i) links to conform to analysis of spectrum and the regulatory restrictions that apply in the country of operation. Regulatory limits Many countries impose EIRP limits (Allowed EIRP) on products operating in the bands used by the PMP/PTP 450(i) Series. Refer to Country specific maximum transmit power (Chapter 9: Reference Information) on page 9-36 to determine what the maximum transmitted power and EIRP for PMP/PTP 450(i) Series that can be used in each of countries and frequency band. Caution It is the responsibility of the user to ensure that the PMP/PTP product is operated in accordance with local regulatory limits. Note Contact the applicable radio regulator to find out whether or not registration of the PMP/PTP 450(i) link is required. Conforming to the limits Ensure the link is configured to conform to local regulatory requirements by configuring the PMP 450(i) AP or PTP 450(i) BHM for the correct country. In the following situations, this does not prevent operation outside the regulations: • When using connectorized ODUs with external antennas, the regulations may require the maximum transmit power to be reduced.

Chapter 3: System planning Radio Frequency planning Page 3-15 Available spectrum The available spectrum for operation depends on the regulatory band. When configured appropriately, the unit will only allow operation on those channels which are permitted by the regulations. Certain regulations have allocated certain channels as unavailable for use: • FCC has allocated part of the 5.1 & 5.2 GHz • ETSI has allocated part of the 5.4 GHz band to weather radar. • UK and some other European countries have allocated part of the 5.8 GHz band to Road Transport and Traffic Telematics (RTTT) systems. The number and identity of channels barred in a given regulatory band is dependent on the channel bandwidth and channel raster selected. Analyzing the RF Environment An essential element in RF network planning is the analysis of spectrum usage and the strength of the signals that occupy the spectrum. Regardless of how these parameters are measured and log or chart the results (through the Spectrum Analyzer feature or by using a spectrum analyzer), ensure measurements are performed: • At various times of day. • On various days of the week. • Periodically into the future. As new RF neighbors move in or consumer devices proliferate in currently used spectrum, this keeps the user aware of the dynamic possibilities for interference within the network. Channel bandwidth Select the required channel bandwidth for the link. The selection depends upon the regulatory band selected. The wider the channel bandwidth, the greater the capacity. As narrower channel bandwidths take up less spectrum, selecting a narrow channel bandwidth may be a better choice when operating in locations where the spectrum is very busy. Both ends of the link must be configured to operate on the same channel bandwidth.

Chapter 3: System planning Radio Frequency planning Page 3-16 Anticipating Reflection of Radio Waves In the signal path, any object that is larger than the wavelength of the signal can reflect the signal. Such an object can even be the surface of the earth or of a river, bay or lake. The wavelength of the signal is approximately • 2 inches (or 5 cm) for 5.4 GHz and 5.8 GHz signals. • 12 inches for 900 MHz signals A reflected signal can arrive at the antenna of the receiver later than the non-reflected signal arrives. These two or more signals cause the condition known as multipath. Multipath may increase or decrease the signal level, resulting in overall attenuation that may be higher or lower than that caused by the link distance. This is problematic at the margin of the link budget, where the standard operating margin (fade margin) may be compromised. Obstructions in the Fresnel Zone The Fresnel (pronounced fre·NEL) Zone is a three-dimensional volume around the line of sight of an antenna transmission. Objects that penetrate this area can cause the received strength of the transmitted signal to fade. Out-of-phase reflections and absorption of the signal result in signal cancellation. The foliage of trees and plants in the Fresnel Zone can cause signal loss. Seasonal density, moisture content of the foliage, and other factors such as wind may change the amount of loss. Plan to perform frequent and regular link tests if you must transmit through foliage. Planning for co-location The first step to avoid interference in wireless systems is to set all AP/BHMs to receive timing from a synchronization source (Cluster Management Module, or Universal Global Positioning System). This ensures that the modules are in sync and start transmitting at the same time each frame. The second step to avoid interference is to configure parameters on all AP/BHMs of the same frequency band in proximity such that they have compatible transmit/receive ratios (all stop transmitting each frame before any start receiving). This avoids the problem of one AP/BHM attempting to receive the signal from a distant SM/BHS while a nearby AP/BHM transmits, which could overpower that signal. The following parameters on the AP/BHM determine the transmit/receive ratio: • Downlink Data percentage • (reserved) Contention slots If OFDM (PMP/PTP 450(i), PMP/PTP 230) and FSK (PMP/PTP 1x0) APs/BHMs of the same frequency band are in proximity, or if you want BHMs set to different parameters then you must use the Frame Calculator to identify compatible settings for APs/BHMs.

Chapter 3: System planning Radio Frequency planning Page 3-17 The Frame Calculator is available on the web management interface Tools > Frame Calculator. To use the Frame Calculator, type into the calculator various configurable parameter values for each proximal AP/BHM and then record the resulting AP/BHM Receive Start value. Next vary the Downlink Data percentage in each calculation and iterate until a calculated AP/BHM Receive Start for all collocated APs/BHMs are within 300 bit times; if possible, within 150 bit times. In Cambium Point-to-Multipoint systems, 10 bit times = 1 µs. For more information on PTP 450(i) co-location, see http://www.cambiumnetworks.com/solution-papers Multiple OFDM Access Point Clusters When deploying multiple AP clusters in a dense area, consider aligning the clusters as shown below. However, this is only a recommendation. An installation may dictate a different pattern of channel assignments.

Chapter 3: System planning Link planning Page 3-19 Link planning This section describes factors to be taken into account when planning links, such as range, obstacles path loss and throughput. LINKPlanner is recommended. Range and obstacles Calculate the range of the link and identify any obstacles that may affect radio performance. Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the risk of interference. This information is necessary in order to achieve an accurate link feasibility assessment. The PMP/PTP 450(i) Series is designed to operate in Non-Line-of-Sight (NLoS) and Line-of-Sight (LoS) environments. An NLOS environment is one in which there is no optical line-of-sight, that is, there are obstructions between the antennas. OFDM technology can often use multi-pathing to an advantage to overcome nLOS, especially in cases where the Fresnel zone is only partially blocked by buildings, “urban canyons”, or foliage. OFDM tends to help especially when obstacles are near the middle of the link, and less so when the obstacles are very near the ODU. However, attenuation through walls and trees is substantial for any use of the 5.4 GHz and 5.8 GHz frequency bands. The lower frequency radio waves of 900 MHz radios provide greater penetration through walls, trees and other obstacles, making it optimal for most non-line-of-sight applications. Even with OFDM, these products are not expected to penetrate walls or extensive trees and foliage. Path loss Path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. The path loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal (Fade Margin). The following calculation needs to be performed to judge whether a particular link can be installed: capabilityseasonalfadeexcessspacefree LLLLL <+++_ Where: Is: spacefreeL_ Free Space Path Loss (dB) ex cessL Excess Path Loss (dB) fadeL Fade Margin Required (dB) seasonalL Seasonal Fading (dB)

Chapter 3: System planning Link planning Page 3-20 capabilityL Equipment Capability (dB) Calculating Link Loss The link loss is the total attenuation of the wireless signal between two point-to-multipoint units. The link loss calculation is presented below: Link Loss (dB) = Transmit power of the remote wireless unit (dBm) − Tx Cable loss (dB) − Received power at the local unit (dBm) – Rx cable loss (dB) + Antenna gain at the remote unit (dBi) + Antenna gain at the local unit (dBi) Calculating Rx Signal Level The determinants in Rx signal level are illustrated in Figure 28. Figure 28 Determinants in Rx signal level Rx signal level is calculated as follows: Rx signal level dB = Tx power − Tx cable loss + Tx antenna gain − free space path loss + Rx antenna gain − Rx cable loss Note This Rx signal level calculation presumes that a clear line of sight is established between the transmitter and receiver and that no objects encroach in the Fresnel zone. The linked image cannot be displayed. The file may have been moved, renamed, or deleted. Verify that the link points to the correct file and location.

Chapter 3: System planning Link planning Page 3-21 Calculating Fade Margin Free space path loss is a major determinant in Rx (received) signal level. Rx signal level, in turn, is a major factor in the system operating margin (fade margin), which is calculated as follows: System operating margin (fade margin) dB = Rx signal level dB − Rx sensitivity dB Thus, fade margin is the difference between strength of the received signal and the strength that the receiver requires for maintaining a reliable link. A higher fade margin is characteristic of a more reliable link. Adaptive modulation Adaptive modulation ensures that the highest throughput that can be achieved instantaneously will be obtained, taking account of propagation and interference. When the link has been installed, web pages provide information about the link loss currently measured by the equipment, both instantaneously and averaged. The averaged value will require maximum seasonal fading to be added, and then the radio reliability of the link can be computed. For details of the system throughput, link loss and maximum distance for each frequency band in all modulation modes, see Link on page 9-25.

Chapter 3: System planning Planning for connectorized units Page 3-22 Planning for connectorized units This section describes factors to be taken into account when planning to use connectorized ODUs with external antennas in PMP/PTP 450(i) links. When to install connectorized units The majority of radio links can be successfully deployed with the integrated ODU. However the integrated units may not be sufficient in some areas, for example: • Where the path is heavily obscured by dense woodland on an NLOS link. • Where long LOS links are required. • Where there are known to be high levels of interference. In these areas, connectorized ODUs and external antennas should be used. Choosing external antennas When selecting external antennas, consider the following factors: • The required antenna gain. • Ease of mounting and alignment. • Use dual-polarization antenna (as the integrated antenna). Note Enter the antenna gain and cable loss into the Installation Wizard, if the country selected has an EIRP limit, the corresponding maximum transmit power will be calculated automatically by the unit. Calculating RF cable length (5.8 GHz FCC only) The 5.8 GHz band FCC approval for the product is based on tests with a cable loss between the ODU and antenna of not less than 1.2 dB. If cable loss is below 1.2 dB with a 1.3 m (4 ft) diameter external antenna, the connectorized PMP/PTP 450(i) may exceed the maximum radiated spurious emissions allowed under FCC 5.8 GHz rules. Cable loss depends mainly upon cable type and length. To meet or exceed the minimum loss of 1.2 dB, use cables of the type and length specified in Table 49 (source: Times Microwave). This data excludes connector losses.

Chapter 3: System planning Planning for connectorized units Page 3-23 Table 49 RF cable lengths required to achieve 1.2 dB loss at 5.8 GHz RF cable type Minimum cable length LMR100 0.6 m (1.9 ft) LMR200 1.4 m (4.6 ft) LMR300 2.2 m (7.3 ft) LMR400 3.4 m (11.1 ft) LMR600 5.0 m (16.5 ft)

Chapter 3: System planning Data network planning Page 3-24 Data network planning This section describes factors to be considered when planning PMP/PTP 450(i) data networks. Understanding addresses A basic understanding of Internet Protocol (IP) address and subnet mask concepts is required for engineering your IP network. IP address The IP address is a 32-bit binary number that has four parts (octets). This set of four octets has two segments, depending on the class of IP address. The first segment identifies the network. The second identifies the hosts or devices on the network. The subnet mask marks a boundary between these two sub-addresses. Dynamic or static addressing For any computer to communicate with a module, the computer must be configured to either • use DHCP (Dynamic Host Configuration Protocol). In this case, when not connected to the network, the computer derives an IP address on the 169.254 network within two minutes. • have an assigned static IP address (for example, 169.254.1.5) on the 169.254 network. Note If an IP address that is set in the module is not the 169.254.x.x network address, then the network operator must assign the computer a static IP address in the same subnet. When a DHCP server is not found To operate on a network, a computer requires an IP address, a subnet mask, and possibly a gateway address. Either a DHCP server automatically assigns this configuration information to a computer on a network or an operator must input these items. When a computer is brought on line and a DHCP server is not accessible (such as when the server is down or the computer is not plugged into the network), Microsoft and Apple operating systems default to an IP address of 169.254.x.x and a subnet mask of 255.255.0.0 (169.254/16, where /16 indicates that the first 16 bits of the address range are identical among all members of the subnet).

Chapter 3: System planning Data network planning Page 3-25 DNS Client The DNS Client is used to resolve names of management servers within the operator’s management domain (see Figure 29). This feature allows hostname configuration for NTP servers, Authorization Servers, DHCP relay servers, and SNMP trap servers. Operators may choose to either enter in the FQDN (Fully Qualified Domain Name) for the host name or to manually enter the IP addresses of the servers. Figure 29 Cambium networks management domain Network Address Translation (NAT) NAT, DHCP Server, DHCP Client and DMZ in SM The system provides NAT (network address translation) for SMs in the following combinations of NAT and DHCP (Dynamic Host Configuration Protocol): • NAT Disabled • NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP Server • NAT with DHCP Client(DHCP selected as the Connection Type of the WAN interface) • NAT with DHCP Server • NAT without DHCP NAT NAT isolates devices connected to the Ethernet/wired side of a SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its address for management), terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet/wired side of the SM.

Chapter 3: System planning Data network planning Page 3-26 In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to Point Tunneling Protocol) are supported. DHCP DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the Cambium system. In conjunction with the NAT features, each SM provides: • A DHCP server that assigns IP addresses to computers connected to the SM by Ethernet protocol. • A DHCP client that receives an IP address for the SM from a network DHCP server. DMZ In conjunction with the NAT features, a DMZ (demilitarized zone) allows the assignment of one IP address behind the SM for a device to logically exist outside the firewall and receive network traffic. The first three octets of this IP address must be identical to the first three octets of the NAT private IP address. Developing an IP addressing scheme Network elements are accessed through IP Version 4 (IPv4) addressing. A proper IP addressing method is critical to the operation and security of a network. Each module requires an IP address on the network. This IP address is for only management purposes. For security, you must either: • Assign a non-routable IP address. • Assign a routable IP address only if a firewall is present to protect the module. You assign an IP addresses to computers and network components by either static or dynamic IP addressing. You will also assign the appropriate subnet mask and network gateway to each module. Address Resolution Protocol As previously stated, the MAC address identifies a module in: • Communications between modules. • The data that modules store about each other.

Chapter 3: System planning Data network planning Page 3-27 The IP address is essential for data delivery through a router interface. Address Resolution Protocol (ARP) correlates MAC addresses to IP addresses. For communications to outside the network segment, ARP reads the network gateway address of the router and translates it into the MAC address of the router. Then the communication is sent to MAC address (physical network interface card) of the router. For each router between the sending module and the destination, this sequence applies. The ARP correlation is stored until the ARP cache times out. Allocating subnets The subnet mask is a 32-bit binary number that filters the IP address. Where a subnet mask contains a bit set to 1, the corresponding bit in the IP address is part of the network address. Example IP address and subnet mask In Figure 30, the first 16 bits of the 32-bit IP address identify the network: Figure 30 Example of IP address in Class B subnet Octet 1 Octet 2 Octet 3 Octet 4 IP address 169.254.1.1 10101001 11111110 00000001 00000001 Subnet mask 255.255.0.0 11111111 11111111 00000000 00000000 In this example, the network address is 169.254 and 216 (65,536) hosts are addressable. Selecting non-routable IP addresses The factory default assignments for network elements are: • Unique MAC address • IP address of 169.254.1.1 • Subnet mask of 255.255.0.0 • Network gateway address of 169.254.0.0 For each radio and CMM4, assign an IP address that is both consistent with the IP addressing plan for your network and cannot be accessed from the Internet. IP addresses within the following ranges are not routable from the Internet, regardless of whether a firewall is configured: • 10.0.0.0 – 10.255.255.255 • 172.16.0.0 – 172.31.255.255 • 192.168.0.0 – 192.168.255.255 Also, the subnet mask and network gateway for each CMM4 can be assigned.

Chapter 3: System planning Data network planning Page 3-28 Translation bridging Optionally, the AP can be configured to change the source MAC address in every packet it receives from its SMs to the MAC address of the SM/BHS that bridged the packet, before forwarding the packet toward the public network. In this case: • Not more than 128 IP devices at any time are valid to send data to the AP from behind the SM. • SM populates the Translation Table tab of its Statistics web page, displaying the MAC address and IP address of all the valid connected devices. • Each entry in the Translation Table is associated with the number of minutes that have elapsed since the last packet transfer between the connected device and the SM. • If 128 are connected, and another attempts to connect: o If no Translation Table entry is older than 255 minutes, the attempt is ignored. o If an entry is older than 255 minutes, the oldest entry is removed and the attempt is successful. • The Send Untranslated ARP parameter in the General tab of the Configuration page can be: o Disabled, so that the AP overwrites the MAC address in ARP packets before forwarding them. o Enabled, so that the AP forwards ARP packets regardless of whether it has overwritten the MAC address. This is the Translation Bridging feature, which you can enable in the General page of the Configuration web page in the AP. When this feature is disabled, the setting of the Send Untranslated ARP parameter has no effect, because all packets are forwarded untranslated (with the source MAC address intact). See Address Resolution Protocol on Page 3-26. Engineering VLANs The radios support VLAN functionality as defined in the 802.1Q (Virtual LANs) specification, except for the following aspects of that specification: • Protocols: o Generic Attribute Registration Protocol (GARP) GARV o Spanning Tree Protocol (STP) o Multiple Spanning Tree Protocol (MSTP) o GARP Multicast Registration Protocol (GMRP) • Embedded source routing (ERIF) in the 802.1Q header • Multicast pruning • Flooding unknown unicast frames in the downlink As an additional exception, the AP/BHM does not flood downward the unknown unicast frames to the SM/BHS. A VLAN configuration in Layer 2 establishes a logical group within the network. Each computer in the VLAN, regardless of initial or eventual physical location, has access to the same data. For the network operator, this provides flexibility in network segmentation, simpler management, and enhanced security.

Chapter 3: System planning Data network planning Page 3-29 Special case VLAN numbers This system handles special case VLAN numbers according to IEEE specifications: Table 50 Special case VLAN IDs VLAN Number Purpose Usage Constraint 0 These packets have 802.1p priority, but are otherwise handled as untagged. Must not be used as a management VLAN. 1 Although not noted as special case by IEEE specifications, these packets identify traffic that was untagged upon ingress into the SM and must remain untagged upon egress. This policy is hard-coded in the AP. Must not be used for system VLAN traffic. 4095 This VLAN is reserved for internal use. Must not be used at all. SM membership in VLANs With the supported VLAN functionality, the radios determine bridge forwarding on the basis of not only the destination MAC address, but also the VLAN ID of the destination. This provides flexibility in how SMs are used: • Each SM can be a member in its own VLAN. • Each SM can be in its own broadcast domain, such that only the radios that are members of the VLAN can see broadcast and multicast traffic to and from the SM. • The network operator can define a work group of SMs, regardless of the AP(s) to which they register.

Chapter 3: System planning Data network planning Page 3-30 PMP 450(i) modules provide the VLAN frame filters that are described in Table 51. Table 51 VLAN filters in point-to-multipoint modules Where VLAN is active, if this parameter value is selected … then a frame is discarded if… because of this VLAN filter in the software: entering the bridge/ NAT switch through… Ethernet… TCP/IP… any combination of VLAN parameter settings with a VID not in the membership table Ingress any combination of VLAN parameter settings with a VID not in the membership table Local Ingress Allow Frame Types: Tagged Frames Only with no 802.1Q tag Only Tagged Allow Frame Types: Untagged Frames Only with an 802.1Q tag, regardless of VID Only Untagged Local SM Management: Disable in the SM, or All Local SM Management: Disable in the AP with an 802.1Q tag and a VID in the membership table Local SM Management leaving the bridge/ NAT switch through… Ethernet… TCP/IP… any combination of VLAN parameter settings with a VID not in the membership table Egress any combination of VLAN parameter settings with a VID not in the membership table Local Egress

Chapter 3: System planning Data network planning Page 3-31 Priority on VLANs (802.1p) The radios can prioritize traffic based on the eight priorities described in the IEEE 802.1p specification. When the high-priority channel is enabled on a SM, regardless of whether VLAN is enabled on the AP for the sector, packets received with a priority of 4 through 7 in the 802.1p field are forwarded onto the high-priority channel. Operators may configure priority precedence as 802.1p Then Diffserv (Default) or Diffserv Then 802.1p. Since these priority precedence configurations are independent between the AP and SM, this setting must be configured on both the AP and SM to ensure that the precedence is adhered to by both sides of the link. VLAN settings can also cause the module to convert received non-VLAN packets into VLAN packets. In this case, the 802.1p priority in packets leaving the module is set to the priority established by the DiffServ configuration. If VLAN is enabled, immediately monitor traffic to ensure that the results are as desired. For example, high-priority traffic may block low-priority. Q-in-Q DVLAN (Double-VLAN) Tagging (802.1ad) PMP and PTP modules can be configured with 802.1ad Q-in-Q DVLAN (Double-VLAN) tagging which is a way for an operator to put an 802.1Q VLAN inside of an 802.1ad VLAN. A nested VLAN, which is the original 802.1Q tag and a new second 802.1ad tag, allows for bridging of VLAN traffic across a network and segregates the broadcast domains of 802.1Q VLANs. Q-in-Q can be used with PPPoE and/or NAT. The 802.1ad standard defines the S-VLAN as the Service Provider VLAN and the C-VLAN as the customer VLAN. The radio software does 2 layer Q-in-Q whereby the C-VLAN is the 802.1Q tag and the S-VLAN is the second layer Q tag as shown in Table 52. Table 52 Q-in-Q Ethernet frame Ethernet Header S-VLAN EthType 0x88a8 C-VLAN EthType 0x8100 IP Data EthType 0x0800 The 802.1ad S-VLAN is the outer VLAN that is configurable on the Configuration > VLAN web page of the AP/BHM. The Q-in-Q EtherType parameter is configured with a default EtherType of 0x88a8 in addition to four alternate EtherTypes that can be configured to aid in interoperability with existing networks that use a different EtherType than the default. The C-VLAN is the inner VLAN tag, which is the same as 802.1Q. As a top level concept, this operates on the outermost tag at any given time, either “pushing” a tag on or “popping” a tag off. This means packets will at most transition from an 802.1Q frame to an 801.ad frame (with a tag “pushed” on) or an untagged 802.1 frame (with the tag “popped” off. Similarly, for an 802.1ad frame, this can only transition from an 802.1ad frame to an 802.1Q frame (with the tag “popped” off) since the radio software only supports 2 levels of tags.

Chapter 3: System planning Network management planning Page 3-32 Network management planning This section describes how to plan for PMP/PTP 450(i) links to be managed remotely using SNMP. Planning for SNMP operation Cambium modules provide the following SNMP traps for automatic notifications to the NMS: • coldStart, which signals that the SNMPv2c element is reinitializing itself and that its configuration may have been altered. • warmStart, which signals that the SNMPv2c element is reinitializing such that its configuration is unaltered. • authenticationFailure, which signals that the SNMPv2c element has received a protocol message that is not properly authenticated (contingent on the snmpEnableAuthenTraps object setting). • linkDown, as defined in RFC 1573 • linkUp, as defined in RFC 1573 • egpNeighborLoss, as defined in RFC 1213 • whispGPSInSync, which signals a transition from not synchronized to synchronized. • whispGPSOutSync, which signals a transition from synchronized to not synchronized. • whispRegComplete, which signals registration completed. • whispRegLost, which signals registration lost. • whispRadarDetected, which signals that the one-minute scan has been completed, radar has been detected and the radio will shut down. • whispRadarEnd, which signals that the one-minute scan has been completed, radar has not been detected and the radio will resume normal operation. Note The proprietary MIBs are provided in the PMP/PTP 450(i) Series software download files in the support website (see Contacting Cambium Networks on page 1). Enabling SNMP Enable the SNMP interface for use by configuring the following attributes in the SNMP Configuration page: • SNMP State (default disabled) • SNMP Version (default SNMPv2c) • SNMP Port Number (default 161)

Chapter 3: System planning Security planning Page 3-33 Security planning This section describes how to plan for PMP/PTP 450(i) links to operate in secure mode. • Managing module access by passwords • Filtering protocols and ports • Port Configuration Isolating AP/BHM from the Internet Ensure that the IP addresses of the AP/BHM in the network: • are not routable over the Internet. • do not share the subnet of the IP address of your user. RFC 1918, Address Allocation for Private Subnets, reserves for private IP networks three blocks of IP addresses that are not routable over the Internet: • /8 subnets have one reserved network, 10.0.0.0 to 10.255.255.255. • /16 subnets have 16 reserved networks, 172.16.0.0 to 172.31.255.255. • /24 subnets have 256 reserved networks, 192.168.0.0 to 192.168.255.255. Encrypting radio transmissions Cambium fixed wireless broadband IP systems employ the following form of encryption for security of the wireless link: • DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system. • AES (Advanced Encryption Standard): An over-the-air link encryption option that uses the Rijndael algorithm and 128-bit keys to establish a higher level of security than DES. AES products are certified as compliant with the Federal Information Processing Standards (FIPS 197) in the U.S.A.

Chapter 3: System planning Security planning Page 3-34 Planning for HTTPS operation Before starting to configure HTTPS operation, ensure that the cryptographic material listed in Table 53 is available. Table 53 HTTPS security material Item Description Quantity required User Defined Security Banner The banner provides warnings and notices to be read by the user before logging in to the ODU. Use text that is appropriate to the network security policy. Normally one per link. This depends upon network policy. Port numbers for HTTP, HTTPS and Telnet Port numbers allocated by the network. As allocated by network. Planning for SNMPv3 operation SNMP security mode Decide how SNMPv3 security will be configured. MIB-based security management uses standard SNMPv3 MIBs to configure the user-based security model and the view-based access control model. This approach provides considerable flexibility, allowing a network operator to tailor views and security levels appropriate for different types of user. MIB-based security management may allow a network operator to take advantage of built-in security management capabilities of existing network managers. Web-based security management allows an operator to configure users, security levels, privacy and authentication protocols, and passphrases using the PMP/PTP 450(i) web-based management interface. The capabilities supported are somewhat less flexible than those supported using the MIB-based security management, but will be sufficient in many applications. Selection of web-based management for SNMPv3 security disables the MIB-based security management. PMP/PTP 450(i) does not support concurrent use of MIB-based and web-based management of SNMPv3 security. Web-based management of SNMPv3 security Initial configuration of SNMPv3 security is available only to HTTP or HTTPS user accounts with security role of Security Officer. Identify the format used for SNMP Engine ID. The following formats are available: • MAC address (default) • 5 and 32 hex characters (the hex character input is driven by RFC 3411 recommendations on the Engine ID)

Chapter 3: System planning Security planning Page 3-35 Identify the user names and security roles of initial SNMPv3 users. Two security roles are available: • Read Only • System Administrator Identify the security level for each of the security roles. Three security levels are available: (a) No authentication, no privacy (b) Authentication, no privacy (c) Authentication, privacy If authentication is required, identify the protocol. The authentication protocol available is MD5. If privacy will be used, identify the protocol. The privacy protocol available is cbc-des. Managing module access by passwords From the factory, each module has a preconfigured administrator-level account in the name root, which initially requires no associated password. When you upgrade a module: • An account is created in the name admin. • Both admin and root inherit the password that was previously used to access the module, if: o Full Access password, if one was set. o Display-Only Access password, if one was set and no Full Access password was set. Caution If you use Wireless Manager, do not delete the root account from any module. If you use a NMS that communicates with modules through SNMP, do not delete the root account from any module unless you first can confirm that the NMS does not rely on the root account for access to the modules. Each module supports four or fewer user accounts, regardless of account levels. The available levels are • ADMINISTRATOR, who has full read and write permissions. This is the level of the root and admin users, as well as any other administrator accounts that one of them creates. • INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the installer cannot add or delete users or change the password of any other user. • TECHNICIAN, who has permissions to modify basic radio parameters and view informational web pages. • GUEST, who has no write permissions and only a limited view of General Status tab. • Admin, Installer and Tech accounts can be configured as READ-ONLY. This will allow the account to only see the items. The ability to view information of General Status tab can be controlled by the "Site Information Viewable to Guest Users" under the SNMP tab.

Chapter 3: System planning Security planning Page 3-36 From the factory default state, configure passwords for both the root and admin account at the ADMINISTRATOR permission level, using the Account > Change Users Password page. (If configure only one of these, then the other will still require no password for access into it and thus remain a security risk.) If you are intent on configuring only one of them, delete the admin account. The root account is the only account that CNUT uses to update the module. After a password has been set for any ADMINISTRATOR-level account, initial access to the module GUI opens the view of GUEST level. Planning for RADIUS operation Configure RADIUS where remote authentication is required for users of the web-based interface. Remote authentication has the following advantages: • Control of passwords can be centralized. • Management of user accounts can be more sophisticated. For example; users can be prompted by a network manager to change passwords at regular intervals. As another example, passwords can be checked for inclusion of dictionary words and phrases. • Passwords can be updated without reconfiguring multiple network elements. • User accounts can be disabled without reconfiguring multiple network elements. Remote authentication has one significant disadvantage in a wireless link product such as PMP/PTP 450(i). If the wireless link is down, a unit on the remote side of the broken link may be prevented from contacting a RADIUS Server, with the result that users are unable to access the web-based interface. One useful strategy would be to combine RADIUS authentication for normal operation with a single locally-authenticated user account for emergency use. PMP 450(i) SM provides a choice of the following authentication methods: • EAP-MSCHAPv2 • EAP-TTLS Ensure that the authentication method selected in PMP/PTP 450(i) is supported by the RADIUS server. Filtering protocols and ports Configure filters for specified protocols and ports from leaving the AP/BHM and SM/BHS and entering the network. This protects the network from both intended and inadvertent packet loading or probing by network users. By keeping the specified protocols or ports off the network, this feature also provides a level of protection to users from each other. Protocol and port filtering is set per AP/SM/BH. Except for filtering of SNMP ports, filtering occurs as packets leave the AP/SM/BH. For example, if SM is configured to filter SNMP, then SNMP packets are blocked from entering the SM and, thereby, from interacting with the SNMP portion of the protocol stack on the SM.

Chapter 3: System planning Security planning Page 3-37 Port Filtering with NAT Enabled Where NAT is enabled on the SM/BHS, the filtering can be enabled for only the user-defined ports. The following are examples for situations where the configure port can be filtered where NAT is enabled: • To block a subscriber from using FTP, you can filter Ports 20 and 21 (the FTP ports) for both the TCP and UDP protocols. • To block a subscriber from access to SNMP, you can filter Ports 161 and 162 (the SNMP ports) for both the TCP and UDP protocols. Note In only the SNMP case, filtering occurs before the packet interacts with the protocol stack. Protocol and Port Filtering with NAT Disabled Where NAT is disabled on the SM/BHS, the filtering can be enabled for both protocols and the three user-defined ports. Using the check boxes on the interface, it can be either: • Allow all protocols except those that user wish to block. • Block all protocols except those that user wish to allow. Allow or block any of the following protocols: • PPPoE (Point to Point Protocol over Ethernet) • Any or all of the following IPv4 (Internet Protocol version 4) protocols: • Any or all of the following IPv4 (Internet Protocol version 4) protocols: o SMB (Network Neighborhood) o SNMP o Bootp Client o Bootp Server o Up to 3 user-defined ports o All other IPv4 traffic (see Figure 29) • Any or all of the following IPv6 (Internet Protocol version 6) protocols: o SMB (Network Neighborhood) o SNMP o Bootp Client o Bootp Server o Up to 3 user-defined ports o All other IPv6 traffic (see Figure 29) • Filter Direction – Upstream and Downstream • ARP (Address Resolution Protocol)

Chapter 3: System planning Security planning Page 3-38 Figure 31 Categorical protocol filtering The following are example situations in which the protocol filtering is configured where NAT is disabled: • If a subscriber is blocked from only PPPoE and SNMP, then the subscriber retains access to all other protocols and all ports. • If PPPoE, IPv4, and Uplink Broadcast are blocked, and also check the All others selection, then only Address Resolution Protocol is not filtered. The ports filtered as a result of protocol selections in the Protocol Filtering tab of the SM/BHS are listed in Table 54.

Chapter 3: System planning Security planning Page 3-40 Encrypting downlink broadcasts An AP can be enabled to encrypt downlink broadcast packets such as the following: • ARP • NetBIOS • broadcast packets containing video data on UDP. The encryption used is DES for a DES-configured module and AES for an AES-configured module. Before the Encrypt Downlink Broadcast feature is enabled on the AP, air link security must be enabled on the AP. Isolating SMs in PMP In an AP, SMs in the sector can be prevented from directly communicating with each other. In CMM4, the connected APs can be prevented from directly communicating with each other, which prevents SMs that are in different sectors of a cluster from communicating with each other. In the AP, the SM Isolation parameter is available in the General tab of the Configuration web page. Configure the SM Isolation feature by any of the following selections from drop-down menu: • Disable SM Isolation (the default selection). This allows full communication between SMs. • Enable Option 1 - Block SM destined packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication. • Enable Option 2 - Forward SM destined packets upstream. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise may have been handled SM to SM, through the Ethernet port of the AP. In the CMM and the CMM4, SM isolation treatment is the result of how to manage the port-based VLAN feature of the embedded switch, where all traffic can be switched from any AP to a specified uplink port. However, this is not packet level switching. It is not based on VLAN IDs. Filtering management through Ethernet Configure the SM to disallow any device that is connected to its Ethernet port from accessing the IP address of the SM. If the Ethernet Access Control parameter is set to Enabled, then: • No attempt to access the SM management interface (by http, SNMP, ftp, or tftp) through Ethernet is granted. • Any attempt to access the SM management interface over the air (by IP address, presuming that LAN1 Network Interface Configuration, Network Accessibility is set to Public, or by link from the Session Status or Remote Subscribers tab in the AP) is unaffected.

Chapter 3: System planning Security planning Page 3-41 Allowing management from only specified IP addresses The Security sub-menu of the Configuration web page in the AP/BHM and SM/BHS includes the IP Access Control parameter. Specify one, two, or three IP addresses that must be allowed to access the management interface (by HTTP, SNMP, FTP or TFTP). If the selection is: • IP Access Filtering Disabled, then management access is allowed from any IP address, even if the Allowed Source IP 1 to 3 parameters are populated. • IP Access Filtering Enabled, and specify at least one address in the Allowed Source IP 1 to 3 parameter, then management access is limited to the specified address(es). Configuring management IP by DHCP The Configuration > IP web page of every radio contains a LAN1 Network Interface Configuration, DHCP State parameter that, if enabled, causes the IP configuration (IP address, subnet mask, and gateway IP address) to be obtained through DHCP instead of the values of those individual parameters. The setting of this DHCP state parameter is also viewable, but is not settable, in the Network Interface tab of the Home page. In the SM/BHS, this parameter is settable • in the NAT tab of the Configuration web page, but only if NAT is enabled. • in the IP tab of the Configuration web page, but only if the Network Accessibility parameter in the IP tab is set to Public. Controlling PPPoE PADI Downlink Forwarding The AP supports the control of forwarding of PPPoE PADI (PPPoE Active Discovery Initiation) packets. This forwarding is configured on the AP GUI Configuration > Radio page by parameter PPPoE PADI Downlink Forwarding. When set to “Enabled”, the AP allows downstream and upstream transmission of PPPoE PADI packets. When set to “Disabled”, the AP does NOT allow PPPoE PADI packets to be sent out of the AP RF interface (downstream) but will allow PPPoE PADI packets to enter the RF interface (upstream) and exit the Ethernet interface.

Power density exposure limit Install the radios for the PMP/PTP 450(i) family of wireless solutions so as to provide and maintain the minimum separation distances from all persons. The applicable power density exposure limit for RF energy in the 4.9, 5.4 and 5.8 GHz frequency bands is 10 W/m2. The applicable power density exposure limit for RF energy in the 900 MHz frequency band is 6 W/m2. For more information, see Human exposure to radio frequency energy on page 4-22.

Chapter 4: Legal and regulatory information Compliance with safety standards Page 4-24 Calculation of power density The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst case analysis. Details of the assessment to EN50383:2002 can be provided, if required. Peak power density in the far field of a radio frequency point source is calculated as follows: Where: Is: S power density in W/m2 P maximum average transmit power capability of the radio, in W G total Tx gain as a factor, converted from dB d distance from point source, in m Rearranging terms to solve for distance yields: Calculated distances and power compliance margins Table 59 and Table 60 shows calculated minimum separation distances, recommended distances and resulting margins for each frequency band and antenna combination for the USA and Canada. These are conservative distances that include compliance margins. At these and greater separation distances, the power density from the RF field is below generally accepted limits for the general population. PMP 450(i) equipment adheres to all applicable EIRP limits for transmit power when operating in MIMO mode. Separation distances and compliance margins include compensation for both transmitters. Explanation of terms used in Table 59 and Table 60: P burst – maximum average transmit power during transmit burst (Watt) P – maximum average transmit power of the radio (Watt) G – total transmit gain as a factor, converted from dB S – power density (Watt/m2) d – minimum safe separation distance from point source (meters) 24.dGPSπ=SGPd.4.π=

Chapter 4: Legal and regulatory information Compliance with safety standards Page 4-27 Note Gain of antenna in dBi = 10 * log(G). The regulations require that the power used for the calculations is the maximum power in the transmit burst subject to allowance for source-based time-averaging. At 5.4 GHz and EU 5.8 GHz, the products are generally limited to a fixed EIRP which can be achieved with the Integrated Antenna. The calculations above assume that the maximum EIRP allowed by the regulations is being transmitted. Remarque Gain de l'antenne en dBi = 10 * log(G). Les règlements exigent que la puissance utilisée pour les calculs soit la puissance maximale de la rafale de transmission soumis à une réduction pour prendre en compte le rapport cyclique pour les signaux modulés dans le temps. Pour une opération dans la CEE dans les bandes 5,4 GHz et 5,8 GHz, les produits sont généralement limités à une PIRE qui peut être atteinte avec l'antenne intégrée. Les calculs ci-dessus supposent que la PIRE maximale autorisée par la réglementation est atteinte. Note If there are no EIRP limits in the country of deployment, use the distance calculations for FCC 5.8 GHz for all frequency bands. At FCC 5.8 GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the distance proportionally to the antenna gain. Remarque Si aucune limite de PIRE existe pour le pays de déploiement, utilisez les calculs de distance pour FCC 5,8 GHz pour toutes les bandes de fréquence. Pour la band FCC 5,8 GHz et les antennes entre 0,6 m (2 pieds) et 1,8 m (6 pieds), modifier la distance proportionnellement au gain de l'antenne.

Australia Notification 900 MHz17 modules must be set to transmit and receive only on center channels of 920, 922, or 923 MHz so as to stay within the ACMA approved band of 915 MHz to 928 MHz for the class license and not interfere with other approved users. After taking into account antenna gain (in dBi), 900 MHz modules’ transmitter output power (in dBm) must be set to stay within the legal regulatory limit of 30 dBm (1 W) EIRP for this 900 MHz frequency band. Regulatory Requirements for CEPT Member States (www.cept.org) When operated in accordance with the instructions for use, Cambium Wireless equipment operating in the 5.1 GHz and 5.4 GHz bands is compliant with CEPT Resolution 229 (REV. WRC-12). Operating the PMP/PTP 450(i) in the bands 5150 to 5350 MHz and 5470 to 5725 MHz is granted providing it is not causing interference to the existing primary services allocated to those bands. For compliant operation in the 5250 to 5350 MHz band, the transmit power from the integrated antenna or a connectorized antenna shall be limited to a maximum mean EIRP of 200 mW and a maximum mean EIRP density of 10 mW/MHz in any 1 MHz band. For compliant operation in the 5470 to 5725 MHz band, the transmit power shall be restricted to a maximum of 250 mW with a maximum mean EIRP of 1 W and a maximum mean EIRP density of 50 mW/MHz in any 1 MHz band. For compliant operation in the bands 5 250-5 350 MHz and 5 470-5 725 MHz, the PMP/PTP 450(i) employs transmitter power control. For EU member states, RLAN equipment in the 5.4GHz bands is exempt from individual licensing under Commission Recommendation 2003/203/EC. Contact the appropriate national administrations for details on the conditions of use for the bands in question and any exceptions that might apply. Also see www.ero.dk for further information. Cambium Radio equipment operating in the 5470 to 5725 MHz band are categorized as “Class 1” devices within the EU in accordance with ECC DEC(04)08 and are “CE” marked to show compliance with the European Radio & Telecommunications Terminal Equipment (R&TTE) directive 1999/5/EC. The relevant Declaration of Conformity can be found at http://www.cambiumnetworks.com/support/ec_doc/ . 17 900 MHz support planned for future release.

Chapter 4: Legal and regulatory information Compliance with radio regulations Page 4-31 A European Commission decision, implemented by Member States on 31 October 2005, makes the frequency band 5470-5725 MHz available in all EU Member States for wireless access systems. Under this decision, the designation of Canopy 5.4GHz products become “Class 1 devices” and these do not require notification under article 6, section 4 of the R&TTE Directive. Consequently, these 5.4GHz products are only marked with the symbol and may be used in any member state.

Grounding and protective earth The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is the user’s responsibility to install the equipment in accordance with national regulations. In the USA follow the requirements of the National Electrical code NFPA 70-2005 and 780-2004 Installation of Lightning Protection Systems. In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in different countries and therefore it is recommended that installation of the outdoor unit be contracted to a professional installer. Powering down before servicing Always power down and unplug the equipment before servicing.

Chapter 5: Preparing for installation Safety Page 5-3 Primary disconnect device The ODU power supply is the primary disconnect device. External cables Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the outdoor environment. For outdoor copper Cat5e Ethernet interfaces, always use Cat5e cable that is gel-filled and shielded with copper-plated steel. RF exposure near the antenna Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the ODU before undertaking maintenance activities in front of the antenna. Minimum separation distances Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate RF energy as soon as they are powered up. Never work in front of the antenna when the ODU is powered. Install the ODUs so as to provide and maintain the minimum separation distances from all persons. For minimum separation distances, see Calculated distances and power compliance margins on page 4-24. Grounding and lightning protection requirements Ensure that the installation meets the requirements defined in Grounding and lightning protection on page 3-8. Grounding cable installation methods To provide effective protection against lightning induced surges, observe these requirements: • Grounding conductor runs are as short, straight and smooth as possible, with bends and curves kept to a minimum. • Grounding cables must not be installed with drip loops. • All bends must have a minimum radius of 200 mm (8 in) and a minimum angle of 90°. A diagonal run is preferable to a bend, even though it does not follow the contour or run parallel to the supporting structure. • All bends, curves and connections must be routed towards the grounding electrode system, ground rod, or ground bar.

Chapter 5: Preparing for installation Safety Page 5-4 • Grounding conductors must be securely fastened. • Braided grounding conductors must not be used. • Approved bonding techniques must be used for the connection of dissimilar metals. Siting ODUs and antennas ODUs, external antennas and GPS receivers are not designed to survive direct lightning strikes. For this reason they must be installed in Zone B as defined in Lightning protection zones on page 3-9. Mounting in Zone A may put equipment, structures and life at risk. Thermal Safety The ODU enclosure may be hot to the touch when in operation. The ODU must not be operated in ambient temperatures exceeding 40°C unless mounted in a Restricted Access Location. For more information, see ODU ambient temperature limits on page 3-10. Warning Do not install the ODU in a location where the ambient temperature could exceed 40°C unless this is a Restricted Access Location as defined by EN 60950-1. Alerte L’unité externe ne doit pas être installée dans un endroit où la température ambiante est supérieure à 40C à moins que l’accès soit limité au personnel autorisé.

Chapter 5: Preparing for installation Preparing for installation Page 5-5 Preparing for installation ODU pre-configuration It is common practice to pre-configure the units during staging before site installation by performing the following tasks: • Error! Reference source not found. • Error! Reference source not found. • Error! Reference source not found. • Error! Reference source not found. • Error! Reference source not found. • Error!

Reference source not found. • Error! Reference source not found. • Error! Reference source not found. • Error! Reference source not found. • Error! Reference source not found. If the units are to be pre-configured during staging, the safety precautions below MUST be observed. Preparing personnel In no event shall Cambium Networks be liable for any injury or damage caused during the installation of the Cambium PMP/PTP 450(i) equipment. Ensure that only qualified personnel undertake the installation of a PMP/PTP 450(i) system. Ensure that all safety precautions are observed. Preparing inventory Perform the following inventory checks: • Check that the correct components are available, as described in Ordering the components on page 2-42. • Check the contents of all packages against their packing lists.

Chapter 5: Preparing for installation Preparing for installation Page 5-6 Preparing tools Check that following specific tools are available, in addition to general tools: • RJ45 crimp tool (it must be the correct tool for the type of RJ45 being used). • Personal Computer (PC) with 10 or 100 or 1000 BaseT Ethernet port • Internet Explorer or Firefox • Ethernet patch cables

Chapter 5: Preparing for installation Testing system components Page 5-7 Testing system components The best practice is to connect all components—AP/BHM, SMs/BHS, GPS antenna (if applicable) and CMM (if applicable)—in a test setting and initially configure and verify them before deploying them to an installation. In this way, any configuration issues are worked out before going on-site, on a tower, in the weather, where the discovery of configuration issues or marginal hardware is more problematic and work-flow affecting. Unpacking Components When a delivery arrives, inspect all packages immediately for damages. Carefully unpack the equipment, verify that all the components have arrived as per order and are in good condition. Save all packaging materials for equipment transportation to the installation site. Preparing the ODU After the equipment is unpacked, the units may be configured for staging tests. Use either of two methods to configure an AP/BHM: • Use the Quick Start feature of the product (via GUI menu Quick Start) • Manually set each parameter After changing configuration parameters on a GUI web page: • Before you leave a web page, click the Save button to save the change(s) • After making change(s) on multiple web pages, click the Reboot button to reboot the module and implement the change(s) Configuring the Computing Device for Test If the computer is configured for Dynamic Host Configuration Protocol (DHCP), disconnect the computer from the network. If the computer is instead configured for static IP addressing • Set the static address in the 169.254 network • Set the subnet mask to 255.255.0.0. For detailed instructions, see section Configuring the management PC on page 5-15.

Chapter 5: Preparing for installation Testing system components Page 5-8 Factory default Configuration From the factory, the APs/BHMs and SMs/BHSs are all configured to not transmit on any frequency. This configuration ensures that equipment operators do not accidentally turn on an unsynchronized module. Site synchronization of modules is required because • modules: o cannot transmit and receive signals at the same time. o use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink frames. • when one module transmits while an unintended module nearby receives signal, the transmitting module may interfere with or desense the receiving module. In this context, interference is self-interference (within the same network). ODU interfaces See section PMP/PTP 450(i) interfaces on page 2-7 ODU diagnostic LEDs See section AP/BHM LEDs on page 2-11. See section SM/BHS LEDs on page 2-12. Recommended Tools for Installation The following tools may be needed for installation: Table 62 Tools for PMP and PTP 450(i) equipment installation Equipment to Be Installed Tools Required AP or BHM • 3 mm Allen Wrench Used for connecting the antenna mating bracket to the rear of the AP housing • Crescent Wrench Pair Used for tightening cable glands • Self-amalgamating and PVC Tape Used for weatherproofing N-type connections

Chapter 5: Preparing for installation Testing system components Page 5-9 Equipment to Be Installed Tools Required AP or BHM or BHS Antenna • 13 mm Spanner Wrench (or Ratchet Spanner Wrench) Pair Used for connecting the antenna (sector or omni for AP, or directional for BH)base to the pole/mast mounting bracket • Self-amalgamating and PVC Tape Used for weatherproofing N-type connections • N-type Torque Wrench (not required but recommended) Used for assuring proper tightening of N-type connectors terminating the RF cables SM • Wrench/driver (depending on operator’s choice of clamps) Used for tightening clamps to the pole • Alignment tone adapter / headset Used for aligning the SM to the AP Universal Global Positioning System • Philips Screwdriver Used for attaching the UGPS unit to the pole/mast mounting bracket • 13mm Spanner Wrench (or Ratchet Spanner Wrench) Used for connecting the mounting bracket’s U-bolt to the antenna or mast Cabling • Electrician’s Scissors or Wire Cutters Used for cutting wire to length • RJ-11/RJ-45 Crimping Tool Used for stripping RJ-11/RJ-45 cables and for terminating cable ends • Cable Testing Device Used to ensure that cables are properly constructed Standards for Wiring Modules automatically sense whether the Ethernet cable in a connection is wired as straight-through or crossover. Operators may use either straight-through or crossover cable to connect a network interface card (NIC), hub, router, or switch to these modules. For a straight-through cable, use the EIA/TIA-568B wire color-code standard on both ends. For a crossover cable, use the EIA/TIA-568B wire color-code standard on one end, and the EIA/TIA-568A wire color-code standard on the other end.

Chapter 5: Preparing for installation Testing system components Page 5-10 Best Practices for Cabling The following practices are essential to the reliability and longevity of cabled connections: • Use only shielded cables to resist interference. • For vertical runs, provide cable support and strain relief. • Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal expansion and contraction and to facilitate terminating the cable again when needed. • Include a drip loop to shed water so that most of the water does not reach the connector at the device. • Properly crimp all connectors. • Use dielectric grease on all connectors to resist corrosion. • Use only shielded connectors to resist interference and corrosion. Wiring Connectors The following diagrams correlate pins to wire colors and illustrate crossovers where applicable. Pin 1, relative to the lock tab on the connector of a straight-through cable is located as shown below. Figure 32 Pin 1 location

Page 10-1 Chapter 10: Troubleshooting This chapter contains procedures for identifying and correcting faults in a PMP/PTP 450(i) link. These procedures can be performed either on a newly installed link, or on an operational link if communication is lost, or after a lightning strike. The following topics are described in this chapter: • General troubleshooting procedure on page 10-2 • Troubleshooting procedures on page 10-5 • Power-up troubleshooting on page 10-14 • Registration and connectivity troubleshooting on page 10-15

Chapter 10: Troubleshooting General troubleshooting procedure Page 10-2 General troubleshooting procedure General planning for troubleshooting Effective troubleshooting depends in part on measures that you take before you experience trouble in your network. Cambium recommends the following measures for each site: • Identify troubleshooting tools that are available at your site (such as a protocol analyzer). • Identify commands and other sources that can capture baseline data for the site. These may include: o Ping o Tracert or traceroute o Link Capacity Test results o Throughput data o Configuration tab captures o Status tab captures o Session logs o Web browser used • Start a log for the site. • Include the following information in the log: o Operating procedures o Site-specific configuration records o Network topology o Software releases, boot versions and FPGA firmware versions o Types of hardware deployed o Site-specific troubleshooting processes o Escalation procedures • Capture baseline data into the log from the sources listed above

Chapter 10: Troubleshooting General troubleshooting procedure Page 10-3 General fault isolation process Effective troubleshooting also requires an effective fault isolation methodology that includes the following: • Attempting to isolate the problem to the level of a system, subsystem, or link, such as o AP to SM o AP to CMM4 o AP to GPS o Backhaul(BH) o Backhaul(BH) to CMM4 o Power • Researching Event Logs of the involved equipment • Interpreting messages in the Event Log • Answering the questions listed in the following sections. • Reversing the last previous corrective attempt before proceeding to the next. • Performing only one corrective attempt at a time. Questions to help isolate the problem When a problem occurs, attempt to answer the following questions: • What is the history of the problem? o Have we changed something recently? o Have we seen other symptoms before this? • How wide-spread is the symptom? o Is the problem on only a single SM? (If so, focus on that SM.) o Is the problem on multiple SMs? If so is the problem on one AP in the cluster? (If so, focus on that AP) is the problem on multiple, but not all, APs in the cluster? (If so, focus on those APs) is the problem on all APs in the cluster? (If so, focus on the CMM4 and the GPS signal.) • Based on data in the Event Log o does the problem correlate to External Hard Resets with no WatchDog timers? (If so, this indicates a loss of power. Correct your power problem.) o is intermittent connectivity indicated? (If so, verify your configuration, power level, cables and connections and the speed duplex of both ends of the link). o does the problem correlate to loss-of-sync events? • Are connections made via shielded cables? • Does the GPS antenna have an unobstructed view of the entire horizon? • Has the site grounding been verified?

Chapter 10: Troubleshooting General troubleshooting procedure Page 10-4 Secondary Steps After preliminary fault isolation is completed through the above steps, follow these: • Check the Canopy knowledge base (https://support.cambiumnetworks.com/forum) to find whether other network operators have encountered a similar problem. • Proceed to any appropriate set of diagnostic steps. These are organized as follows: o Module has lost or does not establish connectivity on page 10-5 o NAT/DHCP-configured SM has lost or does not establish connectivity on page 10-7 o SM Does Not Register to an AP on page 10-9 o Module has lost or does not gain sync on page 10-10 o Module does not establish Ethernet connectivity on page 10-11 o CMM4 does not pass proper GPS sync to connected modules on page 10-12 o Module Software Cannot be Upgraded on page 10-13 o Module Functions Properly, Except Web Interface Became Inaccessible on page 10-13

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-5 Troubleshooting procedures Proceed to any appropriate set of diagnostic steps. These are organized as follows: • Module has lost or does not establish connectivity on page 10-5 • NAT/DHCP-configured SM has lost or does not establish connectivity on page 10-7 • SM Does Not Register to an AP on page 10-9 • Module has lost or does not gain sync on page 10-10 • Module does not establish Ethernet connectivity on page 10-11 • CMM4 does not pass proper GPS sync to connected modules on page 10-12 • Module Software Cannot be Upgraded on page 10-13 • Module Functions Properly, Except Web Interface Became Inaccessible on page 10-13 Module has lost or does not establish connectivity To troubleshoot a loss of connectivity, perform the following steps: Procedure 4 Troubleshooting loss of connectivity 1 Isolate the end user/SM from peripheral equipment and variables such as routers, switches and firewalls. 2 Set up the minimal amount of equipment. 3 On each end of the link: • Check the cables and connections. • Verify that the cable/connection scheme—straight-through or crossover—is correct. • Verify that the LED labeled LNK is green. • Access the General Status tab in the Home page of the module. • Verify that the SM is registered. • Verify that Received Power Level is -87 dBm or higher. • Access the IP tab in the Configuration page of the module. • Verify that IP addresses match and are in the same subnet. • If RADIUS authentication is configured, ensure that the RADIUS server is operational

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-6 4 On the SM end of the link: • Verify that the PC that is connected to the SM is correctly configured to obtain an IP address through DHCP. • Execute ipconfig (Windows) or ifconfig (linux) • Verify that the PC has an assigned IP address. 5 On each end of the link: • Access the General tab in the Configuration page of each module. • Verify that the setting for Link Speeds (or negotiation) matches that of the other module. • Access the Radio tab in the Configuration page of each module. • Verify that the Radio Frequency Carrier setting is checked in the Custom Radio Frequency Scan Selection List. • Verify that the Color Code setting matches that of the other module. • Access the browser LAN settings (for example, at Tools > Internet Options > Connections > LAN Settings in Internet Explorer). • Verify that none of the settings are selected. • Access the Link Capacity Test tab in the Tools page of the module. • Perform a link test • Verify that the link test results show efficiency greater than 90% in both the uplink and downlink • Execute ping. o Verify that no packet loss was experienced. o Verify that response times are not significantly greater than " 4 ms from AP to SM " 15 ms from SM to AP o Replace any cables that you suspect may be causing the problem. Note A ping size larger than 1494 Bytes to a module times out and fails. However, a ping of this size or larger to a system that is behind a Canopy module typically succeeds. It is generally advisable to ping such a system, since Canopy handles that ping with the same priority as is given all other transport traffic. The results are unaffected by ping size and by the load on the Canopy module that brokers this traffic. 6 After connectivity has been re-established, reinstall network elements and variables that you removed in Step 1.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-7 NAT/DHCP-configured SM has lost or does not establish connectivity Before troubleshooting this problem, identify the NAT/DHCP configuration from the following list: • NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP Server • NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) • NAT with DHCP Server • NAT without DHCP To troubleshoot a loss of connectivity for a SM configured for NAT/DHCP, perform the following steps.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-8 Procedure 5 Troubleshooting loss of connectivity for NAT/DHCP-configured SM 1 Isolate the end user/SM from peripheral equipment and variables such as routers, switches and firewalls. 2 Set up the minimal amount of equipment. 3 On each end of the link: • Check the cables and connections. • Verify that the cable/connection scheme—straight-through or crossover—is correct. • Verify that the LED labeled LNK is green. 4 At the SM: • Access the NAT Table tab in the Logs web page. • Verify that the correct NAT translations are listed. RESULT: NAT is eliminated as a possible cause if these translations are correct. 5 If this SM is configured for NAT with DHCP, then at the SM: • Execute ipconfig (Windows) or ifconfig (Linux) • Verify that the PC has an assigned IP address. • If the PC does not have an assigned IP address, then o enter ipconfig /release “Adapter Name”. o enter ipconfig /renew “Adapter Name”. o reboot the PC. o after the PC has completed rebooting, execute ipconfig o if the PC has an assigned IP address, then o access the NAT DHCP Statistics tab in the Statistics web page of the SM. o verify that DHCP is operating as configured. 6 After connectivity has been re-established, reinstall network elements and variables that you removed in Step 1.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-9 SM Does Not Register to an AP To troubleshoot a SM failing to register to an AP, perform the following steps. Procedure 6 Troubleshooting SM failing to register to an AP 1 Access the Radio tab in the Configuration page of the SM. 2 Note the Color Code of the SM. 3 Access the Radio tab in the Configuration page of the AP. 4 Verify that the Color Code of the AP matches that of the SM. 5 Note the Radio Frequency Carrier of the AP. 6 Verify that the value of the RF Frequency Carrier of the AP is selected in the Custom Radio Frequency Scan Selection List parameter in the SM. 7 In the AP, verify that the Max Range parameter is set to a distance slightly greater than the distance between the AP and the furthest SM that must register to this AP. 8 Verify that no obstruction significantly penetrates the Fresnel zone of the attempted link. 9 Access the General Status tab in the Home page of each module. 10 Remove the bottom cover of the SM to expose the LEDs. 11 Power cycle the SM. RESULT: Approximately 25 seconds after the power cycle, the green LED labeled LNK must light to indicate that the link has been established. If the orange LED labeled SYN is lit instead, then the SM is in Alignment mode because the SM failed to establish the link. 12 If the AP is configured to require authentication, ensure proper configuration of RADIUS or Pre-shared AP key. 13 In this latter case and if the SM has encountered no customer-inflicted damage, then request an RMA for the SM.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-10 Module has lost or does not gain sync To troubleshoot a loss of sync, perform the following steps. Procedure 7 Troubleshooting loss of sync 1 Access the Event Log tab in the Home page of the SM 2 Check for messages with the following format: RcvFrmNum = ExpFrmNum = 3 If these messages are present, check the Event Log tab of another SM that is registered to the same AP for messages of the same type. 4 If the Event Log of this second SM does not contain these messages, then the fault is isolated to the first SM. If the Event Log page of this second SM contains these messages, access the GPS Status page of the AP. 5 If the Satellites Tracked field in the GPS Status page of the AP indicates fewer than 4 or the Pulse Status field does not indicate Generating Sync, check the GPS Status page of another AP in the same AP cluster for these indicators. GPS signal acquisition must not take longer than 5 minutes from unit startup. 6 If these indicators are present in the second AP, then: • Verify that the GPS antenna still has an unobstructed view of the entire horizon. • Visually inspect the cable and connections between the GPS antenna and the CMM4. If this cable is not shielded, replace the cable with shielded cable 7 If these indicators are not present in the second AP, visually inspect the cable and connections between the CMM4 and the AP antenna. If this cable is not shielded, replace the cable with shielded cable.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-11 Module does not establish Ethernet connectivity To troubleshoot a loss of Ethernet connectivity, perform the following steps: Procedure 8 Troubleshooting loss of Ethernet connectivity 1 Verify that the connector crimps on the Ethernet cable are not loose. 2 Verify that the Ethernet cable is not damaged. 3 If the Ethernet cable connects the module to a network interface card (NIC), verify that the cable is pinned out as a straight-through cable. 4 If the Ethernet cable connects the module to a hub, switch, or router, verify that the cable is pinned out as a crossover cable. 5 Verify that the Ethernet port to which the cable connects the module is set to auto-negotiate speed. 6 Verify VLAN configuration in the network, which may cause loss of module access if the accessing device is on a separate VLAN from the radio. 7 Power cycle the module. RESULT: Approximately 25 seconds after the power cycle, the green LED labeled LNK must light up to indicate that the link has been established. If the orange LED labeled SYN is lit instead, then the module is in Alignment mode because the module failed to establish the link. 8 In this latter case and if the module has encountered no customer-inflicted damage, then request an RMA for the module.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-12 CMM4 does not pass proper GPS sync to connected modules If the Event Log tabs in all connected modules contain Loss of GPS Sync Pulse messages, perform the following steps. Procedure 9 Troubleshooting CMM4 not passing sync 1 Verify that the GPS antenna has an unobstructed view of the entire horizon. 2 Verify that the GPS coaxial cable meets specifications. 3 Verify that the GPS sync cable meets specifications for wiring and length. 4 If the web pages of connected modules indicate any of the following, then find and eliminate the source of noise that is being coupled into the GPS sync cable: • In the GPS Status page: o anomalous number of Satellites Tracked (greater than 12, for example) o incorrect reported Latitude and/or Longitude of the antenna • In the Event Log page: o garbled GPS messages o large number of Acquired GPS Sync Pulse messages GPS signal acquisition must not take longer than 5 minutes from unit startup. 5 If these efforts fail to resolve the problem, then request an RMA for the CMM4.

Chapter 10: Troubleshooting Troubleshooting procedures Page 10-13 Module Software Cannot be Upgraded If your attempt to upgrade the software of a module fails, perform the following steps. Procedure 10 Troubleshooting an unsuccessful software upgrade 1 Download the latest issue of the target release and the associated release notes. 2 Verify that the latest version of CNUT is installed. 3 Compare the files used in the failed attempt to the newly downloaded software. 4 Compare the procedure used in the failed attempt to the procedure in the newly downloaded release notes. 5 If these comparisons reveal a difference, retry the upgrade, this time with the newer file or newer procedure. 6 If, during attempts to upgrade the FPGA firmware, the following message is repeatable, then request an RMA for the module: Error code 6, unrecognized device Module Functions Properly, Except Web Interface Became Inaccessible If a module continues to pass traffic and the SNMP interface to the module continues to function, but the web interface to the module does not display, perform the following steps: Procedure 11 Restoring web management GUI access 1 Enter telnet DottedIPAddress. RESULT: A telnet session to the module is invoked. 2 At the Login prompt, enter root. 3 At the Password prompt, enter PasswordIfConfigured. 4 At the Telnet +> prompt, enter reset. RESULT: The web interface is accessible again and this telnet connection is closed. Note The module may also be rebooted via an SNMP-based NMS (Wireless Manager, for example) 5 If the issue persists, turn off any SNMP-based network/radio monitoring software and repeat steps 1-4.

Chapter 10: Troubleshooting Registration and connectivity troubleshooting Page 10-15 Registration and connectivity troubleshooting SM/BMS Registration If no SMs are registered to this AP, then the Session Status tab displays the simple message No sessions. In this case, try the following steps. 1 More finely aim the SM or SMs toward the AP. 2 Recheck the Session Status tab of the AP for the presence of LUIDs. 3 If still no LUIDs are reported on the Session Status tab, click the Configuration button on the left side of the Home page. RESULT: The AP responds by opening the AP Configuration page. 4 Click the Radio tab. 5 Find the Color Code parameter and note the setting. 6 In the same sequence as you did for the AP directly under Configuring Link for Test on Page 5-15, connect the SM to a computing device and to power. 7 On the left side of the SM Home page, click the Configuration button. RESULT: The Configuration page of the SM opens. 8 Click the Radio tab. 9 If the transmit frequency of the AP is not selected in the Custom Radio Frequency Scan Selection List parameter, select the frequency that matches. 10 If the Color Code parameter on this page is not identical to the Color Code parameter you noted from the AP, change one of them so that they match. 11 At the bottom of the Radio tab for the SM, click the Save Changes button. 12 Click the Reboot button. 13 Allow several minutes for the SM to reboot and register to the AP. 14 Return to the computing device that is connected to the AP. 15 Recheck the Session Status tab of the AP for the presence of LUIDs.

DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DFS See Dynamic Frequency Selection DHCP Dynamic Host Configuration Protocol, defined in RFC 2131. Protocol that enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the system. See http://www.faqs.org/rfcs/rfc2131.html. See also Static IP Address Assignment. DiffServ Differentiated Services, consistent with RFC 2474. A byte in the type of service (TOS) field of packets whose values correlates to the channel on which the packet should be sent. The value is a numeric code point. Cambium modules map each of 64 code points to values of 0 through 7. Three of these code points have fixed values, and the remaining 61 are settable. Values of 0 through 3 map to the low-priority channel; 4 through 7 to the high-priority channel. The mappings are the same as 802.1p VLAN priorities. (However, configuring DiffServ does not automatically enable the VLAN feature.) Among the settable parameters, the values are set in the AP for all downlinks within the sector and in the SM for each uplink.
