Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios2209866-0022015-09-09The ExtendAir G2 24GHz model number scheme uses the first two digits to define the general frequency band (in GHz) and the last three digits to define the connector and base configuration.• ExtendAir G2 models have one 10/100/1000BaseT PoE port and one additional 10/100/1000BaseT port (see Figure 5)– configured with 25Mbps of full-duplex Ethernet capacity The ExtendAir G2 24GHz models require a clear line-of-sight and proper path clearance to achieve a high-performance, reliable connection. Perform professional path engineering and site planning before installing this equipment. The primary focus of this document is the installation and maintenance of the digital microwave radio, and assumes that path engineering and site planning were already performed.The ExtendAir G2 24GHz radios utilize radio frequencies that are considered ‘unlicensed’ in most countries. This means that the frequency plans and radio configuration are not coordinated with other users of the spectrum. Also, the frequency, channel-center frequencies, occupied bandwidth, and the Transmitter-to-Receiver frequency separation (also known as T/R spacing) are utilized to allow maximum use of the 24 GHz unlicensed band. In many bands, it is necessary to offer unique part numbers to allow coverage of a 'sub-band' of the entire frequency band, and also to address the specific T/R spacing that is required. The following is a table of the configurations supported. In most cases, there are regulations or device-based conditions that limit the use of the device, such as minimum or maximum antenna gain, antenna polarization, and maximum output power, as well as, in some cases, application limits, limited geography of use, and other unique regulations. The link design engineer and/or professional installer must determine these limitations and engineer/install the system within the confines of all local regulations. Also, it is required to examine any regulations that may apply to peripheral equipment, installation and cabling of the system that may be regulated for human safety, electrical code, air-traffic control, and other safety-related categories. In some cases, a need for link registration, coordination, and fees that may apply to the system usage. Please consult your local regulatory organization(s) to determine usage requirements.In almost all cases, the product itself must be authorized for use in your country. Either Exalt or Exalt’s agent must have applied for certification or authorization to allow the sale and deployment of the system within the country. It is also possible that only certain versions or configurations of the device are allowed within a particular country. Please contact Exalt or your authorized Exalt representative for information pertaining to your country. Basic FeaturesThe ExtendAir G2 24GHz Digital Microwave Radios are intended for all-outdoor mounting and designed to be used with an indoor-mounted power injector. For most implementations, the entire unit is typically mounted on a tower or rooftop mast structure, with Ethernet/Power and other optional interface cables running from the unit location, through a structure penetration, and to the power injector and connected communications equipment.Table 1 Supported configurationsBand NameFrequencyBand Edges(GHz)T/R Spacing(MHz)Supported Channel Bandwidths (MHz) # ofSub-Bands(diplexers)WaveguideFlange Type24GHz 24.000–24.250 80/100/112 1 0.219" diameterNote: It is the professional installer’s responsibility to ensure that the radio system is implemented in a legal fashion. Exalt is not liable for any unsafe or illegal installations.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 32015-09-09When mated to the proper antenna, the radio is mounted directly to the antenna, thereby eliminating any RF cabling and associated losses. Figure 2 Cabling and surge suppressionThe ExtendAir G2 24GHz radios provide connections for up to two Gigabit Ethernet data communication interfaces, and are powered by a combined Power/Ethernet cable, and associated power injector. The power injector provides 48VDC to the unit. The power injector and/or external power supply are sold separately.The ExtendAir G2 24GHz radios provide the following primary features and benefits:• Low-latency optimization for voice and data connections• Very high throughput and flexible interface configurations with voice+data combinations• Encryption for extreme wireless security• Easy-to-use management and configuration• Flexible utilized channel bandwidth and modulation selections, with field-interchangeable diplexers for low-cost sparing and easy capacity and frequency coordination• Flexible center frequency tuning for interference avoidance and frequency coordination• Flexible capacity to meet current connection requirements and future growth needs• Carrier-class reliability and performance• Connector covers (for weatherproofing unused connectors)

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 52015-09-09See Configuration and Management for details on how to connect to and use the browser-based GUI interface.Shipping Box ContentsThe terminals are shipped as individual endpoints. As mentioned, it takes two terminals–one TX-H and one TX-V–to make a complete link. An outer box has labeling that indicates the contents of the box, with the part number and serial number details for the radio terminal. The terminal box contains the following items:• Radio terminal• Accessory kit (includes reset connector)• Registration card• Quick-start guidePower solutions are sold separately. Power for the ExtendAir G2 models comply with the 802.3at Power-over-Ethernet (PoE) standard. Any 802.3at PoE device is compliant with these models. You must mount the radio to the proper direct-mount antenna, therefore no mounting hardware is required. Inspect the outer packaging and the contents of the boxes upon receipt. If you suspect any shipping damage or issues with the contents, contact Exalt Customer Care (see Introduction).Outdoor-rated and shielded CAT5e or CAT6 cable, such as Belden 1300A, with RJ-45 connectors is recommended for the Ethernet connections. For Ethernet connections, a maximum length of 100 meters applies to the total length of the cabling between the radio terminal and the first network-aware connection (such as a switch or router).Initial Configuration and Back-to-Back Bench Test Every Exalt digital microwave radio goes through extensive quality testing and performance evaluation over the full operating temperature range prior to shipment. However, before installation, it is strongly advised to perform several tests and tasks that are much more difficult to perform once the radio link endpoints are distant from one another. A back-to-back bench test and pre-configuration will provide confidence that the radio link is operational and properly configured prior to installation, so that if troubleshooting is necessary, the radio hardware and configuration settings are eliminated from the troubleshooting process. Verify the following in the back-to-back testing:• Confirm that the radio system is generally operational– Radios power-up with planned power and wiring solutions– Radio firmware version matches on each terminal (and is ideally the latest version)– RF link connects in both directions– Traffic passes across the link• Configure connected equipment and cabling– Test Ethernet (CAT5e) cabling, any auxiliary connector cabling, and configure all interfaces– Configure IP settings for configuration and managementNote: Register your system as soon as possible. A 2-year Warranty period applies. See Exalt Limited Hardware Warranty Software License and RMA Procedures Agreement.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios6209866-0022015-09-09– Configure passwords and security modes– Become familiar with the configuration and management interfaces through the Exalt GUI interface– Configure radio parameters– Set transmitter output power to engineered or allowed level (see RF Output Power Setting)– Set operating center frequency– Set occupied channel bandwidth and modulation• Make detailed radio performance measurements– Measure transmitter output power– Measure receiver threshold performance– Confirm unfaded error-free performanceSome of these tasks may not be possible or practical within a bench test environment due to the nature of the remote connectivity of peripheral equipment. However, it is good practice to perform as much as possible in this environment to minimize field/installation time and troubleshooting efforts.Detailed performance measurements are usually not required for pre-installation, but can be easily performed at this stage and may be helpful for later troubleshooting efforts or for internal records. During troubleshooting, there may often be a point at which a back-to-back bench test should be performed to verify many or all of the above items, and in the case of a suspected faulty device, to help confirm the fault and determine which end of the system is at fault and in need of repair or replacement.RF Output Power SettingThe maximum RF output power is bounded by one of the following criteria:• Maximum RF output power setting capability of the radio device• Maximum RF output power allowed/authorized by the local government regulations and for this specific device• Maximum effective isotropic radiated power (EIRP) of the transmission system allowed/authorized by the local government regulations and for this specific device• Desired RSL to not exceed the maximum RSL allowed by the device• Desired RSL to minimize/eliminate interference into neighboring systemsCritical Configuration ConsiderationsThe ExtendAir G2 24GHz radios are very dynamic, allowing the installer to optimize and control the performance of the radio system for the intended application. The following parameters must be carefully determined during the link engineering phase:Note: See Back-to-back Bench Testing for detailed instructions.Note: In many cases the radio must be pre-configured for legal maximum output power before connecting to the antenna and transmission system. Instructions for adjusting the output power can also be found in Power.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 72015-09-09•Bandwidth• Mode (modulation)The setting of the above parameters determines the Ethernet throughput. Use a professional link planning tool to determine optimum settings for the above parameters to meet the needs of your application.Note the following generalizations regarding these factors:• The higher the bandwidth, the higher the capacity• The higher the mode, the higher the capacitySingle IP ArchitectureExalt radios have a single IP architecture. The IP resides on the processor for management connectivity. If you are planning to use Out-of-Band management (see the Ethernet Interface Configuration Page), ensure that devices connected to the radio are properly configured. The management port (typically Ethernet 1) must be completely separate from the traffic (router or switch) ports. You can achieve this by using a separate switch or configuring a management-traffic specific VLAN for the radio management port.Radio Default ConfigurationRadios arrive from manufacture in default configuration configured as shown in Table 2.Table 2 Factory default settingsParameter ExtendAir G2 24GHzFrequency Lowest frequency pair supported by software-configured diplexerTransmit Power -25 dBm or lowest power supported by frequency bandBandwidth Minimum value supported by modelMode (modulation) Minimum modulation supported by model (typically QPSK)Link Security Key 000000000000Administration Password passwordUser Password passwordIP Address 10.0.0.1 (for TX-H); 10.0.0.2 (for TX-V)IP Mask 255.0.0.0IP Gateway 0.0.0.0Ethernet Interfaces Alarm Enabled, Auto-negotiateNote: In many cases, the system design will not be identical to the factory default configuration, and in some cases, these differences prohibit the installation of the radio. If at all possible, obtain a computer and configure the radio terminals using the browser-based GUI. See Exalt Graphical User Interface (GUI).

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios8209866-0022015-09-09Radio ResetUse the reset function if the IP address and/or passwords are lost. Use the steps particular to your radio model to perform a critical parameter reset.The following configurations are reset on the radio when performing a reset:• IP address = 10.0.0.1• IP mask = 255.0.0.0• IP gateway = 0.0.0.0• Administration password = password• User password = password• VLAN = disabledPerforming a Reset To perform a radio reset, you must have a mechanism to connect the radio’s RSL/BNC port between the center pin and the shield to provide a “short” between the two conductors. Common methods for this are:• Using the BNC termination provided in the radio accessory kit.• Using a standard voltmeter BNC cable, attach a jumper clip to the voltmeter end to short the two conductors.• Using a BNC male connector assembly, connect or solder a wire or jumper to short the center pin and outer shield.Once the RSL/BNC port shorting mechanism solution is identified, follow this procedure:1Remove the power source, preferably at the AC or PoE DC input.2Remove the RSL/BNC port cover on the radio.3Install the RSL/BNC port shorting mechanism chosen above.4Apply power.5Wait until the internal beeper sounds (approximately 1 minute). You can verify the reset by pinging the 10.0.0.1 default IP address.6Remove the RSL/BNC port shorting mechanism.7Replace the RSL/BNC port cover.Virtual Local Area Network (VLAN)VLAN segments information in a single connection and creates multiple separate connections to secure information of one type or for one set of users from other information types or for other sets of users. Exalt’s VLAN communications implementation adheres to the IEEE standard 802.1q.In most cases, an Exalt radio acting as a Layer 2 bridge between two locations is only required to pass traffic with VLAN tagging. Without additional configuration, all Exalt radios support frame sizes in excess of 1900 bytes, which currently supports all defined VLAN packet sizes.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 92015-09-09Some situations require Exalt radios to act upon VLAN traffic and perform any or all of the following functions:• Connect specific traffic, using VLAN tagging, to a specific port on the radio, such as management traffic to the ETH1/PoE port.• Allow only traffic with specifically assigned VLANs to pass across the link, blocking all other VLANs or any non-VLAN traffic.• Allow management access only through a VLAN connection, leaving the main traffic transparent.• Allow management access without a VLAN connection, but flowing only specific VLAN traffic across the link.Simple Network Management Protocol (SNMP)The Exalt radios primarily use a browser-based graphical user interface (GUI) for radio configuration and management, as described in Exalt Graphical User Interface (GUI). In addition, a command line interface (CLI) is provided for SSH or Telnet access, as described in Command Line Interface (CLI). SNMP is often used for management of larger networks as described here. Use SNMP to manage networked devices and execute the following functions:• GET: Obtain information from the device, such as a configuration setting or parameter.• SET: Change a configuration setting on the device.• TRAP: The device proactively informs the management station of a change of state, usually used for critical alarms or warnings.One feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes.When some parameters are changed, a link may drop and/or management control lost. MIB files allow many parameters to be set at once, allowing only a temporarily dropped link or management control issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and management control. The save (Commit) command is similar to the Update button. Dropped links or management control issues do not occur with every parameter change. Many configuration changes do not impact traffic or management access.Exalt radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing of management data. The SNMPv3 security string matches the admin and user passwords. Passwords must be eight characters or longer. SNMPv1 and SNMPv2 are also supported. Note: If an application only requires the transparent passing of VLAN traffic, disable the VLAN function. Note: MIB files downloadable from the radio are listed on the File Transfer Page. You can also find MIB files for your radio on exaltcom.com. MIBs for Exalt radios are model specific.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios12 209866-0022015-09-09InstallationThis section presents all tasks required to install the Exalt Digital Microwave Radio.Mechanical Configuration and MountingThe ExtendAir G2 24GHz radios are environmentally sealed units intended for deployment outdoors. The device must be deployed within an ambient temperature range as specified, and with non-restrictive airflow around the chassis.Provide proper clearance for all cables and connectors attached to the device.Mounting the SystemYou must mount this radio directly to the antenna. The antenna must be the proper type for this to be accomplished (see Antennas).Figure 4 Direct-mount configurationUse the following steps to direct-mount the radio:1Mount the antenna with the proper polarization alignment, following the instructions provided with the antenna.2Using non-corrosive silicone grease (typically provided with the antenna), grease the rubber O-ring on the antenna fitting.Note: Unless otherwise specified by the manufacturer, the power injector and power supply must be placed indoors or in an enclosure.Note: You must mount the ExtendAir G2 24GHz with the handle facing up (Figure 4). The system utilizes both polarizations of the antenna to achieve the full duplex link and cannot operate properly if the radios are oriented in any other manner.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 152015-09-09PowerThe radio requires a DC power source within specifications via a power-over-Ethernet (PoE) power injector (sold separately). Most PoE injectors take a DC voltage source input or use an AC adapter, or may be integral to a network switch or router.As an alternative to an off-the-shelf 802.3at injector, Exalt provides modular PoE solutions, including a multi-injector rack mount solution, that can properly power the ExtendAir G2 radio. These modular injectors (models A300505, A300501, and A300502) provide proper power to the radio, but the RESET button on these models does not reset the ExtendAir G2 24GHz radio. Pressing the RESET button has no effect on the radio and causes no harm.Applying PowerDo not plug the injector into the main power source first. First, verify that the RF connector is properly terminated (see Power), and then plug in the radio-side connector from the injector to the radio. If the power source can be turned off using a switch, disable the power, plug the power supply side of the injector into the power source, and then enable power to the circuit. If the power source cannot be turned off, plug in to the power input side of the injector to apply power. Exalt strongly recommends that the power supplies be fused or on a separate breaker to ensure against over-voltage and/or over-current situations and to provide some form of protection to the radio electronics and other devices connected to the same supply. In addition, if the power source is subject to significant spikes or variation, power conditioning is a worthwhile investment, as the quality of the power source may have a direct impact on the device operation, performance and/or reliability. An Uninterruptible Power Source (UPS) or other form of battery-backed system protects against brown-out and black-out conditions, and condition the power presented to the injector.Evaluate the opportunity for lightning or other similar surges to be present on the powering system, including the ability for surges to couple to the power wiring system. If an evaluation indicates that there is a potential likelihood for these conditions to occur, additional surge protection is recommended for the input power wiring, especially to protect the radio electronics between the injector and the radio. Ensure that every connection to the device is wired in this manner. While the configuration for surge suppression or line conditioning is of a different type for each kind of signal interface, the opportunity for damage to the device, loss of communications and property is significant. In some cases, there can also be a risk to human life by not protecting against lightning entering a building through wiring or improper grounding. If you do not have experience in this type of installation practice, consult a qualified electrician and/or telecoms professional during the installation and wiring of the equipment.ETH1 (RIGHT) Green LED Solid = Ethernet link present.

Surge protection for the radio protection is highly recommended in areas with any opportunity of lightning. Connect the surge protection using a CAT5e or CAT6 cable no longer than 6'/1m. Ensure that the surge protection device is properly grounded. For the Power/Ethernet cable, specific voltage requirements must be met. The following devices are the only devices currently recommended:• Polyphaser IXG-05• Transtector ALPU 1101-959• Transtector ALPU-1000BT-R• Citel C2MJ8-POE-A/SE• Transtector 1101-1030• Transtector 1101-1080Use the previously mentioned short CAT5e or CAT6 cable for the connection between the radio and the first arrestor. Use bulk outdoor-rated CAT5e or CAT6 cable for the longer run between arrestors, and indoor- or outdoor-rated cable with a standard RJ45 termination for the connection from the egress arrestor and power injector. The cabling between the radio, through all arrestors, and to the power injector must follow a straight-wired convention, maintaining standard Ethernet pairing.Diplexer (Channel Plan) ConfigurationThe ExtendAir G2 24GHz radio has a unique feature that allows field reconfiguration of the TX-H or TX-V Tx/Rx orientation. This allows a single spare unit for both TX-H and TX-V configurations.The transmitter (Tx) and receiver (Rx) tuning is determined by the ID number on the diplexer:• ID #871 indicates that the Tx diplexer is in the horizontal orientation (customer part number E24F732-H).• ID #872 indicates that the Tx diplexer is in the vertical orientation (customer part number E24F732-V).Note: Surge protection is not guaranteed to protect the radio equipment for high surges or direct lightning strikes. Note: Use only outdoor-rated UV-resistant CAT5e or CAT6 cable. The cable that directly connects to the radio must have an outer diameter between 0.25"/6.35 mm and 0.31"/7.87mm. Belden 1300A is recommended. Securely hand-tighten all connectors on the ODU to ensure a weatherproof seal.CAUTION! Removal of the diplexer cover requires special care. The instructions in this section must be followed precisely to maintain performance and weatherproof operation. The Exalt Limited Hardware Warranty Software License and RMA Procedures Agreement may be void if damage to the radio occurs as a result of improper installation.

With the radio handle at the top, diplexer ID #871 Tx/Rx port labels read normally. These labels read upside down for diplexer ID #872. •The Port label indicates the frequency range of the corresponding port (on the underside of the diplexer). One side is Tx and the other is Rx, depending on how it mounts to the radio.• This label also displays the ID number to select on the System Configuration Page. To change the diplexer configuration:1On the antenna-mounting side of the radio chassis, use a 5mm Hex wrench to remove the four (4) chassis cover screws shown in the following photo.2Use a forceful back-and-forth motion to pivot the two halves of the chassis against each other until they separate. Note that the gasket on the center nozzle of the RF section is a tight fit.The picture above shows the radio with the handle at the positioned at top. Use this orientation to determine diplexer orientation. Note: These diplexers have the same frequency range.Note: Since the diplexer cannot be seen without removing the front cover, it is critical that you change the external labeling if you change the diplexer. Labels are provided in the Diplexer Flip Kit.CAUTION! Do not place any object between the seams of the chassis to assist with separation–this will damage the outer diameter gasket.

Consult the manufacturer's instructions for proper mounting, grounding, and wiring of these devices, and for definitive direction. These manufacturer's instructions supersede any information in this section. See Antennas for a list of supported antennas.Initial Antenna MountingThe antenna must be an exact model recommended by the path and site planning engineer(s). Mount the antenna at the proper height, mast/mounting location and polarization orientation as determined by the path and site planning engineer(s). The model type, location, and orientation of the antenna is critical with respect to achieving proper path clearance, as well as to mitigate external or self- interference from nearby or collocated systems operating in or near the same frequency band.The antenna structure must be secure and safe with respect to the mounting of the antenna, transmission system weight, radio housing, and the combined weight of any personnel that may climb or attach to the structure.The combined weight of items and forces on the structure must be carefully considered in the design and construction of the structure. This must include the weight bearing on the structure in the highest wind conditions possible in the region, and with respect to all objects affixed to the structure. If additional objects are affixed to the structure in the future, it may be important to evaluate both the mechanical impact of these planned additions (with respect to wind and weight loading), as well as the potential impact to RF interference and frequency coordination (if additional radio equipment is anticipated). This is especially important if future equipment is likely to operate within the same frequency band.Once the antenna is mounted, cabled, and aligned, your goal is to never require modification. This prior planning is important in the path and site planning stages and in construction of the antenna structure.Follow the antenna manufacturer’s instructions for mechanical mounting of the antenna. Ensure that there is enough room around the antenna for alignment activities (moving the antenna in vertical and horizontal arcs), and for the RF transmission line to connect to the antenna connector unobstructed and within the specified bend radius requirements of the transmission line.At this point, the antenna mounts should be fully secure to the structure, the feed of the antenna securely mounted to the antenna (if the feed is a separate assembly), and the azimuth and elevation adjustments not completely tightened in preparation of the antenna alignment activity. It is a good practice to connect the transmission line to the antenna connector as early in the process as possible, to reduce the opportunity for debris or moisture to enter either the antenna connector or the transmission line Note: The chassis must have the right labels. You must also set the diplexer ID number on the System Configuration Page.Warning! Mount the antenna in a restricted area and in a manner preventing long-term human exposure to the transmitted RF energy. Consult your government guidelines for proper signage and/or safe distance considerations for radio equipment.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios20 209866-0022015-09-09connector. Use a connector cover or other temporary measures to ensure that the connector is kept clear. Take extra care if the antenna is installed during inclement weather to ensure that no moisture gets inside the antenna connector at any time.Now the antenna can be aimed in the general direction required for the link. Use a compass, a reference bearing, binoculars or any other similar device to point the antenna in the direction (generally) of the far end radio, and then slightly tighten the azimuth and elevation adjustments so that the antenna maintains its general position and is safe to be left without additional securing. Refer to the Exalt white paper, Antenna Alignment, for more information on antenna alignment techniques.Antenna AlignmentAntennas must be installed at both ends of the planned link to commence precision alignment. Refer to the Exalt white paper, Antenna Alignment.Antennas are typically aligned using the radio hardware for precise alignment. However, there are many very useful tools available to aid in this process, inclusive of devices specifically designed for the purpose of aligning antennas. Some examples are:• XL Microwave Path Align-R• Teletronics 17-402Use of these devices may be extremely advantageous as compared to using the radio, because they employ many unique facilities to aid in this process. Using these tools also makes it possible to align the antennas before the radio equipment is delivered. However, many installers successfully use the radios as the means for antenna alignment.There are two primary facilities when using the radio to align the antenna:• RSL voltage test point using a volt meter (recommended)A voltmeter with a BNC male connector can be directly connected to the RSL connector on the radio. The RSL test point DC voltage is inversely proportional and numerically calibrated to the received signal level. The voltage rises as the antennas are less in alignment, and falls as antennas are more in alignment. The voltage measurement corresponds to the received signal level in measurements of dBm (a negative number for RSL measurements). For example, an RSL of –60dBm yields an RSL voltage measurement of 0.60VDC; an RSL of –45dBm measures 0.45VDC.• Audio alignment buzzerEnable the audio alignment buzzer through the Exalt GUI. When enabled, the radio enclosure emits a sound. The pitch rises when higher (better) levels of RSL are achieved. Align the antennas until the highest pitch is accomplished. The tone is continuous when the two ends of the radio system are in communication. Otherwise, the buzzer beeps.• Exalt GUI RSL reading indicates the current RSL in dBm.Note: There is a slight delay in RSL readings in the GUI as the RSL levels change. In this case, fine alignment can be done in small adjustments allowing a small gap of time so that the impact of the adjustment on the GUI display catches up to real time. Note: Only use the browser-based GUI for antenna alignment if there are no other means available. If this method is required, refer to Exalt Graphical User Interface (GUI). The RSL reading can be read on a PC or any hand-held computing device that supports an HTML browser and Ethernet connectivity.

Use the Ethernet for a Telnet session over a network connection. SSH or Telnet into the Command Line Interface (CLI)Use an SSH or Telnet connection to access the CLI in the Exalt Digital Microwave Radios. Use the CLI to set key parameters on the system.Connect to the Radio in a SSH or Telnet SessionMake the SSH or Telnet connection to the radio through the Ethernet port. Use Windows and perform the following steps:1Open a command prompt or MS-DOS prompt (Start>Run).2Type C:\>Telnet <IP Address> at the command line:The default IP address is 10.0.0.1 (for the TX-H radio or after default reset). 10.0.0.2 is the IP address for a new (from factory) TX-V radio.TelnetUse Telnet when prompted to enter the administration level login and password. The default administration login is admin and password is password. It is recommended that the default administration password be reset by changed to prevent unauthorized access.Figure 7 shows the menu choices available after log in.Figure 7 CLI root menuNote: The accessing computer must be on the same IP subnet as the radio. The radio has a DHCP server (enabled by default). If the connecting computer is set to obtain its IP parameters from DHCP, the radio configures the accessing computer to 10.0.0.3 or 10.0.0.4. No manual IP configuration is required.$

A computer or hand-held device with a conventional HTML browser and Ethernet port is required. Google Chrome is the preferred browser. Netscape, Mozilla, Microsoft Internet Explorer, and Firefox are also supported. Preparing to ConnectIf the radios are new, both radios are preconfigured as Tx Lo and Tx Hi with default IP addresses of 10.0.0.1 and 10.0.0.2, respectively. If the radios are not new, the IP addresses and Hi/Lo and diplexer configurations may need to be changed. The initial priority is to connect to the radio’s management system to completely configure the radio. Assign the radios different IP addresses, unique to each radio. There are two ways to change the IP address:1Reset the radio to the critical default factory settings (see Radio Reset).2Connect to the GUI using the default IP address (10.0.0.1 or 10.0.0.2), and change the IP address through the GUI interface.Make ConnectionsIt is recommended that one radio at a time be configured, on a bench, before taking the radios to the field for installation. Terminate the RF connector with a 50-Ohm termination or a fixed attenuator of at least 20dB (see Power). Once connected to the radio using Ethernet, log in to the Exalt GUI.Log InUse the following steps to log in to the Exalt GUI.1Open a browser window. Note: To connect to the radio’s Ethernet port and use the GUI interface, the accessing computer must match the radio’s IP address subnet. It is therefore necessary to either change the radio’s IP address through the CLI to match the subnet of the computer, or change the computer’s IP address to match the subnet of the radio (such as, a computer IP address of 10.0.0.10 if trying to connect to a radio set to the factory default IP address of 10.0.0.1).CAUTION! Do not connect the radios in a back-to-back configuration unless the IP addresses of the two radios are verified as different from each other.Note: The IP address subnet of the accessing computer must match the radio’s IP address subnet to connect using Ethernet.$

Use the steps in the Quick Start Guide included with the radio. A summary of the items that need to be configured are:• Radio IP address for each end. – Each end must have a different IP address and cannot match the accessing computer’s IP address or any address assigned if radios are part of a larger network.– It may be required to change the IP address of the accessing computer after changing the IP address of the radio so that the IP subnet matches.– The radio IP address is listed on the Administration Settings Page.• Verify that the two terminals are opposite channel plans.– The product label indicates the frequency band and sub-band of the shipped configuration, such as ending in 1H or H1 (for Band 1, Hi Tx). The opposite end should be 1L or L1 in this case (for Band 1, Lo Tx).– If the warranty warning label that runs across the seam of the two halves of the chassis is missing or broken, the internal diplexer may have been adjusted since shipment. Check the label affixed to the chassis to ensure that it matches the product label. If it does not, the channel configuration likely matches THIS label instead of the product label. If in doubt, disassemble the radio to inspect the orientation of the installed diplexer to ascertain the installed configuration. See Diplexer (Channel Plan) Configuration.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 252015-09-09If all other parameters are still configured at their factory default settings, the radios can now be connected back-to-back to verify that the link is communicating and perform any other desired tests. See Back-to-back Bench Testing for test information.Navigating the GUI describes each page of the GUI. Most configuration parameter settings are intuitive. The following link parameters must match at both ends for the link to communicate:• Link Security Key (Administration Settings Page)•Bandwidth (System Configuration Page)• Modulation (System Configuration Page)• RF Frequency (System Configuration Page), the channel plans match, but are opposite Tx and Rx frequencies for a link.Navigating the GUIThe GUI provides the primary interface for all configuration and management. There are three sections of the main GUI window, as shown in Figure 11:• Summary status information pane (upper-left corner)• Navigation pane• Main windowFigure 11 Exalt GUI window descriptionSummary Status SectionThis section of the Exalt GUI provides a review of the system status. In the screens in Figure 12, the top bar illustrates the alarm condition of the link. The information inside the bar is equivalent to the entry of the Link Name set by the administrator in the Administration Settings page.Note: Changing any of these parameters causes a temporary loss of link. The GUI displays a warning and provides an opportunity to cancel changes.Note: Click the radio IP address link to access that radio for management.SUMMARY STATUSNAVIGATION PANEMAIN WINDOWLINK TOREMOTE RADIO

The information displayed is the IP address and the endpoint identifier (Radio A or Radio B). The right panel summarizes the alarm conditions of the remote radio (the radio linked to the local radio).The Summary Status Section allows the Exalt GUI to be a rudimentary management system. Minimize the browser window to display just the top bar or the top bar and radio information, and open several browsers on the desktop. When a window status changes to yellow or red, you can quickly maximize that window to determine the issues.Figure 12 Summary status informationNavigation PanelIn the navigation panel, pages with sub-pages have a plus (+) to the left of the page link.

The terms local and remote refer to the orientation of the radio terminals relative to the IP address you are managing. When making certain changes to a near-end radio without first making changes to the far-end radio, the link may become disconnected unless configuration changes are reverted to their original settings. When making changes that may disrupt the link, always change the far-end radio first, and then the near-end radio to match.

The Current Value column lists actual settings. Enter desired changes in the New Value column. After entering all desired changes, click the Update button to accept and enable changes. Figure 14 Administration Settings pageMost entries on this page are self-explanatory. The following lists unique or important parameters.• Fill in the date and time fields as soon as practical. Events are captured with time/date stamps, which is valuable information for troubleshooting.• Set the Link Security Key to something other than the factory default setting (12 characters, all zeros) at each end. The link security key must match at both sides of the link. If the security key remains at the factory setting, the radio link is open to sabotage by a party with the same radio model. Each link should have a unique security key. If using the same security key for every link in the network, the radio could link to any other radio with the same security key. This is problematic in multi-radio networks.– Note that the security key must be exactly 12 characters. Any alphanumeric character can be used. The link security key is case sensitive.• Reset the admin and user passwords. These passwords should not match. If the admin password remains at the factory default setting, it provides an opportunity for random reassignment by a network-connected user.Note: Changing the link security key interrupts transmission until the opposite end is changed to match. Always change the far-end radio first, and then change the near-end radio.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 292015-09-09– The new password must be entered twice. If the passwords do not match and the Update button clicked, the password is not changed and remains set to the previous password.• AES (Advance Encryption Standard) can be implemented to provide additional data security for the wireless link. This function requires an upgrade license key (purchased separately). Both radios in the link must have a valid AES upgrade license key to implement AES. Different bit-length encryption license keys (for example, 128-bit and 256-bit) are also available, depending on model type. If the required upgrade license key is present, simply insert a matching hexadecimal string on both terminals and select the Enable AES On option for AES encryption. Note that similar to the administration and user passwords, the AES string must be entered twice for each terminal.

Use SNMP to manage networked devices and execute the following functions:• GET: Obtain information from the device, such as a configuration setting or parameter.• SET: Change a configuration setting on the device.• TRAP: The device proactively informs the management station of a change of state, usually used for critical alarms or warnings. See SNMP Traps.Figure 16 SNMP Configuration pageOne feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes.When some parameters are changed, a link may drop and/or management control lost. MIB files allow many parameters to be set at once, allowing only a temporarily dropped link or management control issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and management control. The save (Commit) command is similar to the Update button. Dropped links or management control issues do not occur with every parameter change. Many configuration changes do not impact traffic or management access.ExtendAir G2 24GHz radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing of management data. The SNMPv3 security string matches the admin and user passwords. Passwords must be eight characters or longer.The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before using the SNMP function.

Enable the SNMPv3 options to allow entering read and read/write user names and passwords. These entries are de-coupled from the standard radio user names and passwords. SNMPv3 provides full management security.SNMP TrapsSNMP traps alert the central network management system with important issues about the radio system. Trap filters are set on the Traps Configuration page (Figure 17). Trap support for all versions of SNMP are provided and can be independently enabled. Enter the IP address to which the traps are directed in the Trap Destination IP Address field. The Ethernet port designated for management must be connected to the network to allow trap information to reach the designated IP address. In a bridged network, this may not require special network settings. In a routed network, the connected router must have a defined path for the IP address.Figure 17 Trap Configuration pageThe following traps are available:• Authentication Trap: This is an SNMP standard trap when password information for SNMP is incorrect. This can help identify unwanted intrusions into the management system and for diagnosis of SNMP issues for valid users.Note: MIB files downloadable from the radio are listed on the File Transfer Page. You can also find MIB files for your radio on exaltcom.com. MIBs for Exalt radios are model specific.Note: Users are encouraged to avoid enabling SNMPv1/v2c support due to known security loopholes in these protocols.Note: The Update button must be clicked to save any changes to this page.

Buffers are provided so that continuous traps are not sent if the RSL is bouncing near the set threshold value. This trap is reset only if the RSL rises to 3dBm above the set threshold value and then drops below that value. Exalt recommends that this trap be set to a value 5dBm or 10dBm above the threshold as a warning that the system has faded and may be approaching an outage.• Temperature Status Trap: This trap is sent when the internal temperature reaches the warning point. This conveys that the external temperature control is in a fault state. Buffers are applied to this trap to avoid multiple traps when the temperature remains near the warning point.

Two types of files can be uploaded: configuration, and radio firmware. When uploading Configuration Files, current configuration parameters are immediately overwritten, and the unit may reboot if configuration changes require a reboot. When uploading radio firmware files, the file is placed into reserve memory space. After the new radio firmware file uploads, use the File Activation page to enable the files (see File Activation Page).Figure 18 File Transfer pageThese types of files can be downloaded: configuration, MIB, Snapshot, and event log. The MIB file refers to the Management Information Base related to the Simple Network Management Protocol (SNMP) function, and is only available on models which support SNMP. See Simple Network Management Protocol (SNMP) Configuration for more information.Use the following steps to upload a file:1Select the type of file to upload (Radio Firmware or Configuration).2Click Browse and choose the file to upload.The file name being uploaded appears next to the Choose File button.3Click Upload to Radio.Note: Check the File Activation Page before uploading radio firmware files. New file uploads overwrite the secondary file location. If important files reside in the primary or secondary file location, download them before uploading the new files.

A copy of the configuration file can also help restore radio settings. In addition, a copy of the Exalt default configuration file is helpful to restore the radio to factory settings. If copying the same configuration file into multiple radios, take as some parameters will match and that may be undesirable. However, it may be easier to change just a subset of parameters rather than every parameter. The following parameters can cause problems or confusion if they match at each of a link:•Radio Name• Endpoint Identifier• IP Address• IP Subnet Mask• Default GatewayConsult the release notes for your release for firmware historical and upgrade paths.The following parameters can match at both ends of the link:•Link Name• Link Security Key (although each link should be different)• Admin and User passwords•Bandwidth• Ethernet configurationsNote: Never change radio firmware file names.

Click the Swap button to place the file in the Alternative File column into the active state and move the file in the Current File column to the Alternative File column.Figure 21 File Activation pageTo load the original firmware that shipped with the radio, use the Revert function. Note that reverting may cause loss of some functionality, as the current firmware may support features not originally supported. When reverting, the current file moves to an alternate file location and the original factory firmware becomes current. If you swap back to the original firmware and no new file has downloaded to the alternate file location, the original alternate file is restored to the alternate file location resulting in the configuration you started with before you reverted. New firmware always downloads to the alternate file location, and must be swapped to become the current firmware.All other radio configurations are maintained. The radio does not return to factory settings, just the original factory firmware. Note: In all cases, the radio reboots after a new file is selected using the Swap function. This places the radio out of service for a short time.

The following lists unique or important parameters.• Set the Diplexer/Filter Configuration parameter to match the installed diplexer of the radio (see Diplexer (Channel Plan) Configuration). – 871–Use this setting for horizontally oriented diplexers. – 872–Use this setting for vertically oriented diplexers.Note: The diplexer settings for both radios must match.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 392015-09-09These settings constrain the T/R spacing as follows:– OTHER–Allows any T/R spacing (for example, for RF loopback support). This allows mis-setting parameters that can result in poor performance or no link. OTHER allows you to set the T/R spacing as needed to avoid interference. – Use this setting for frequency ranges not available with the diplexer ID. If the radio diplexer has never been changed from the manufacture configuration or the change was done following labeling directions in Diplexer (Channel Plan) Configuration, the label on the outside of the radio will match the diplexer configuration. If there is any doubt, remove the diplexer cover to reveal orientation.• Set the Radio Transmit Power (dBm) parameter to the designed level. The professional installer sets this value or dictates the value of this setting to the system administrator following the system design and local regulations. In many cases, this value must be set to a proper value to comply with legal restrictions. Improper values can result in liability to the user and/or installer.– Do not adjust the Radio Transmit Power parameter to a value higher than is legally allowed. – Do not adjust the Radio Transmit Power parameter lower than the link budget and fade margin can afford. Bandwidth T/R< 50 MHz 80 MHz.= 50 MHz 100 MHz.> 50 MHz 112 MHz.Note: For optimum performance, base T/R spacings on the bandwidth in use and greater than or equal to those listed above. For example, for any bandwidth, a T/R spacing of < 80 MHz results in degraded radio performance.Note: This setting has no validation process. You must ensure that the proper T/R spacing is maintained.Note: Changing Radio Transmit Power may temporarily interrupt traffic. Small changes in output power do not normally interrupt traffic, but larger changes may.Note: The link may be lost and unrecoverable through GUI control. If the link is lost due to reduction of Radio Transmit Power, travel to the radio location(s) may be required to reset the value.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios40 209866-0022015-09-09• Set the Antenna Gain (dB) parameter to compute the Calculated EIRP (dBm).• The read-only Calculated EIRP (dBm) field displays the EIRP based on Radio Transmit Power and Antenna Gain (for regulatory compliance purposes).• Set the Bandwidth (MHz) parameter to the value determined in the design/engineering stage. The Bandwidth parameter must also match at both ends of the link. In conjunction with the Mode parameter, the Bandwidth parameter directly relates to the capacity supported. • Adaptive Coded Modulation (ACM) allows the radio to reduce throughput as link conditions fall below what can be supported during normal operation. The advantage is that instead of the link being down or highly errored, the link remains up for longer periods, but with reduced throughput.• ACM Mode parameter enables or disables ACM. Some regulatory environments may not allow ACM or may require special licensing. Check your local regulations before enabling this feature.• ACM Policy parameter selects the modulation to run and how fast to switch between settings. – Aggressive settings switch the radio from modulation to modulation at the moment that the signal-to-noise ratio allows. This can result in rapidly changing throughput characteristics, but always provides the highest throughput, even if the currently selected setting is not error-free. – Conservative applies hysteresis (that is, the time-based dependence of a system’s output on current and past inputs) to the switching decision, waiting longer to make a change in the ‘upward’ direction. Switching to a lower modulation is instantaneous, but the radio ‘waits’ to switch back to a higher modulation state until the signal-to-noise ratio is above the threshold for that setting. The result is slightly slower changes between modulations and less overall switching (which could be less disruptive to some network operations).• ACM Base Modulation parameter sets the minimum modulation for the radio to select. There are cases where regulatory limits may apply that govern the minimum modulation that can be used, which is sometimes based on licensing. Check your local regulations before deciding this parameter setting.Note: If you enter an invalid combination of Radio Transmit Power and Antenna Gain, a regulatory-specific warning appears (ETSI warning shown below) and the out-of-specs field is highlighted. Click OK to change the values per regulatory requirements.Note: Changing Bandwidth will temporarily interrupt traffic. The Bandwidth parameter must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Bandwidth changes the radio’s threshold. A wider bandwidth has worse threshold performance and improved interference immunity, therefore if changing to a narrower bandwidth, there is an opportunity that the link may be lost and unrecoverable through GUI control. Check the available fade margin to determine if the impact to threshold and increased bandwidth is acceptable to maintain the link and the desired performance. If the link is lost due to increasing the Bandwidth parameter, travel to the radio location(s) may be required to reset the value.

Muting a connection is desirable when connected equipment senses Ethernet signaling and makes decisions (such as, spanning tree protocol enable) based on the Ethernet signal. The ETH1 port cannot be muted, as it is always used for primary management and PoE.It may be desirable to disable the alarming of any connector if it is not used.The Management parameter allows determination of management information using the following management modes:• Inband: Management traffic is carried over the air and is available from all connectors on either end of the link (Figure 24).• Out-of-Band: Management traffic is not carried over the air and is only available from the port(s) configured for Management. Note: The port configured for Management and the traffic ports must be logically separated by using VLANs or a separate switch (see Single IP Architecture).

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 432015-09-09Figure 24 In-Band and Out-of-Band Management • Port-to-Port: Management traffic remains separate from data traffic without requiring out-of-band management or VLAN configuration. This allows any Ethernet port on the link to be logically mapped to the same port at the other end of the link without requiring VLANs to be configured. The traffic passing through these mapped ports is not accessible from any of the other available Ethernet ports on either side of the link.• The Flow Control setting allows the enabling of 802.3 Ethernet flow control. This feature is selectable on all Ethernet interface ports individually, and enables flow control signaling from the radio to the connected network device. ‘Pause’ packets are issued when incoming traffic capacity is greater than current capacity. This feature is only operational when used in conjunction with Rate Limiting and/or QoS.• The Alarm function can be enabled or disabled for each port. Generally, all constantly connected port alarms should be enabled, and unused or maintenance-only ports should have alarms disabled. • The Mute setting allows signaling to connected network devices when the radio link is down such as for spanning tree protocol.• When enabled, the DHCP feature provides a basic DHCP function to ease interfacing with a computer. DHCP is enabled by default. If the Ethernet port on the computer is set for DHCP addressing, on radio bootup (for up to 10 minutes) or when an Ethernet link is sensed for a management port, the radio provides an IP address to the computer that is two digits higher than the radio’s IP address (for example, if the radio’s IP address is 10.0.0.1, the computer’s IP address will be 10.0.0.3). The radio also senses any DHCP server on the network and if detected, mutes its own internal DHCP function.

It can also be hard set to match the connected network device, but in some cases, if it is set to 1000BaseT/Full, it may become impossible for the radio to communicate with a 100BaseT device.Note: The 802.3 compliance standard requires auto-negotiation for 1000BASE-T Gigabit Ethernet over a twisted pair.

The Exalt radios still pass VLAN and non-VLAN traffic across the link, but do not examine the VLAN traffic or act upon it. Enable VLAN using the Exalt GUI for expanded VLAN support.Figure 25 VLAN Configuration pageVLAN configurations are maintained even when VLAN is disabled. That is, the VLANs can be configured and the configuration saved, even though they are not active until VLAN is enabled. Use the following methods to restore the management connection if a mistake was made assigning the management VLAN and access cannot be restored: Reset the radio to the critical factory defaults (see Radio Reset) and reconfigure the VLAN settings. ExtendAir G2 24GHz radios support filter lists of up to 4094 VLAN IDs. Four VLAN configurations are provided:• Enabled & Block Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other traffic, including untagged traffic, is not passed across the link. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in this lower table.Note: Once a management VLAN is configured or modified and the Update button clicked, the management connection will likely be lost. The management connection to the radio must follow the configuration to the assigned VLAN. After configuring and enabling the management VLAN on the radio, reconfigure your network’s management access to match the settings on the radio.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios46 209866-0022015-09-09• Enabled & Pass Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other VLAN traffic is not passed across the link, and untagged traffic is passed across the link with no changes. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in this lower table.• Enabled & Tag Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other VLAN traffic is not passed across the link, and untagged traffic is tagged with the programmed Default VLAN, per interface, as set in the upper table. Any interface requiring the default VLAN ID to pass must have the Default VLAN ID listed in the table below. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in the lower table.• Management only: All traffic is passed transparently, except the radio is managed on an assigned Management VLAN ID, as programmed in the upper table.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios50 209866-0022015-09-09ATPC Configuration PageAutomatic Transmit Power Control (ATPC) is often required by regulatory agencies for radio systems in congested areas. The radio runs normally at a reduced output power level, and only raises its output power when necessary, such as during a fade. Regulatory agencies may mandate the transmit power standards used under normal conditions (set on the System Configuration Page), the maximum transmit power used with ATPC, ATPC-specific timers, and operator evaluations of the link if and when mandated conditions are exceeded. Figure 29 ATPC Configuration page•Enable ATPC Mode to allow more radio links to share a spectrum providing less opportunity for interference.On the Diagnostic Charts Page, the Far-End Transmit Power chart displays when any combination of ATPC or Receiver Overload Protection is enabled.•ATPC RSL Threshold determines the RSL where ATPC becomes active. When ATPC is enabled, the far-end transmitter output power is increased to maintain the near-end ATPC receive threshold, dB-for-dB, as the link fades or recovers. Enable ATPC on both ends of the link for proper functionality.•ATPC Max Tx Power controls the maximum power the radio transmits when ATPC is enabled. The Radio Transmit Power value shown at the top of this table indicates that entry for ‘normal’ (low transmit power) operation, which is set on the System Configuration page.•When the ATPC Timer Control timers are enabled, the ATPC maximum status alarm turns yellow (minor) when the ATPC timers are exceeded (see Alarms Page). If timers are mandated, set the

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 512015-09-09ATPC threshold as low as possible to reduce the time that ATPC is active. Current timer status is available on the ATPC Statistics Page. There are event log entries for all timer events. •Receiver Overload Protection is similar to ATPC. It ensures that the maximum RSL is not exceeded by reducing transmit power of the far-end radio so that radio specifications are met. Receiver Overload Protection reduces far-end transmit power in un-faded conditions, or during up-fades, to ensure that the maximum input RSL specification is met at all times and not overloaded. Receiver Overload Protection and ATPC can run independently or simultaneously. The radio runs at standard transmit power levels as long as the Overload Protection RSL threshold is not exceeded. If exceeded, the radio reduces the far-end transmit power to maintain the target RSL.For links that normally run at a value exceeding radio specifications, use the maximum output power in the System Configuration setting and enable Receiver Overload Protection to attenuate the value for normal conditions and restore output power during fades.•Set the RSL High Watermark Event Trigger value to a few dB above the normal (un-faded) RSL link or to a value at or above -33dBm, whichever is higher, to minimize the number of entries in the event log caused by running at or near the maximum RSL specification.Note: Ensure that radio implementation meets local regulations. There may be limitations to the use of the Receiver Overload Protection feature. Consult your local regulatory authorities.

It is normal for the internal temperature to be above the ambient temperature, so the temperature reading may be higher than the highest specified ambient temperature. When the internal electronics reach a point that is higher than the normal temperature rise at the highest ambient temperature, the temperature alarm turns yellow. Power down the radio as soon as possible, and investigate the cause of the temperature rise before the radio is put back in service. In almost all cases, a temperature alarm is due to external causes.Link Security • Green = Security keys match• Red = Security keys do not match• Grey = Link is downTable 6 Alarm status indicators (Continued)Label Status

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios54 209866-0022015-09-09Performance PageThis page provides statistical information about the performance of the system in relation to the integrity of the user data and the RF link. Figure 31 Radio Performance page• The Current BER field indicates the current bit error rate of the link. If the link is operating perfectly, this should indicate zero. Generally, the link should remain at a BER less than 1x10-6 (one bit out of every million bits errored). This is the threshold performance specification and the standard to which the link was engineered. However, radio links can and are affected by weather, interference, and other external sources and will occasionally have a higher error rate. A link remains operational unless the BER exceeds 1x10-3 (1 bit out of every hundred bits errored). Consult the link design engineer for an understanding of the predicted error rate of the radio link as it has been designed. Many applications are unaffected by bit errors. However, if the link operator is providing a service guarantee, this value may need to be monitored or examined in cases of service issues. The behavior of BER in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities.• Errored Seconds (ES) indicates the total number of seconds that occurred where there was at least one bit error since the last time that the radio statistics counter was reset. Generally, ES are not a significant concern, so long as they are not continuous or above the anticipated performance based on the original link engineering goals. If ES are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors previously listed, ES can and will occur in any radio link. Once again, consult the link engineer to determine the original

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 552015-09-09design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive ES.• Unavailable Seconds (also called UAS) are similar to ES, but this counter keeps track of every second where the bit error rate equals or exceeds 1x10-3, as well as any seconds where there is a complete loss of radio communication, over the period since the last counter reset. If Unavailable Seconds are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors listed above, Unavailable Seconds can and do occur in any radio link. Consult the link engineer to determine the original design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive Unavailable Seconds.• Current RSL is the measurement of the received signal level at the radio antenna port. This is the measured level of the RF signal coming from the opposite end of the radio link. The link was engineered to a specific RSL by the link design engineer, and this RSL should be obtained during installation and remain relatively stable during the operation of the link. RSL can and will vary as a result of weather changes and other external sources, such as path obstructions. Once again, this variation was part of the original design to achieve a certain level of performance over time. Bit errors occur when the RSL falls to a level within roughly 3dB of the threshold specification. When the RSL falls below the threshold specification, the link disconnects and will not reconnect until the RSL is above the threshold specification. The behavior of RSL in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities.• Minimum RSL indicates the worst (lowest) received signal level that occurred since the last counter reset. It is helpful to know if the RSL dropped significantly from the normal level, or has reached a level near or below threshold.• Maximum RSL indicates the best (highest) RSL that occurred since the last counter reset. This indicates the best performance of the radio link, which is normally equal to the installed value, and is usually the designed value.• Minimum RSL Timestamp indicates the date and time when the Minimum RSL occurred. This is helpful for general troubleshooting, and especially comparing to items in the event log or diagnostic charts from the same time period.• (ATPC and/or Receiver Overload Protection enabled) Far-End Transmit Power and Max Far End Tx Timestamp provide an instant record to assist interpretation of the current RSL as it relates to ATPC and/or Receive Overload Protection actively changing the far-end transmit power. The timestamp is recorded for the last instance that maximum far-end transmit power initiated.• Time Since Reset indicates the amount of time passed since the last counter reset. This helps to quantify the seriousness of other statistics, such as ES and Unavailable Seconds, if there have been high numbers of ES and/or Unavailable Seconds over a relatively short period of time.All end-of-link statistics can be independently reset using the respective reset statistics button. It is good practice to reset the statistics during link commissioning (after all antenna alignment is complete and stable RSL at designed levels is achieved, and no more system reboots are anticipated). Regularly review this page to record performance and reset the statistics so that the counters can more precisely pinpoint issues.Note: Unavailable Seconds do not register as ES. In other words, the ES counter counts all seconds that are errored NOT INCLUDING the seconds that were classified as unavailable. The total number of seconds with errors or outages is the sum of ES and Unavailable Seconds.

This page illustrates the historical (and current) performance for three parameters: RSL, Radio Temperature, and BER. This data is a current snapshot. Data is cleared on a radio power cycle or reload/reset.The horizontal scale illustrates 120 points of time measurement and is synchronized on all three graphs. The scale displays in minutes, hours, or days from the last two hours (120 minutes), five days (120 hours), or four months (120 days). All information is stored, so all of these periods are available for short- and long-term performance analysis. The right side of a graph represents the most recent measurement, and data ‘marches’ from the right-to-left at every interval.The vertical scale of each chart independently scales to show the maximum resolution based on the maximum variation of the data over the selected time measurement. Figure 37 Diagnostic Charts pageUse the cursor to point to any spot on any of the three charts, and all three charts illustrate the measurements taken for that time interval in the upper-left corner of each chart. The time interval is

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios64 209866-0022015-09-09indicated by T=(value). This is followed by the value of the measurement, listing the highest value, lowest value and average value measured over that time interval.For example, if the displayed time interval is minutes, and the cursor is held at the T=17 mark on the horizontal axis, the measurements shown indicate performance from 17 minutes ago. The high/low/average values shown on each chart are measurements made across that specific one-minute interval.The Far-End Transmit Power chart displays when any combination of ATPC or Receiver Overload Protection is enabled (see ATPC Configuration Page). This chart shows the far-end transmitter changes that are occurring relative to the provided RSL information. Since the far-end transmit power can change on links using ATPC or Receiver Overload Protection, this information is very useful for troubleshooting.Changes in RSL often have an impact on BER, and this can be confirmed by looking for synchronized events. When BER events occur without corresponding changes in RSL, this normally indicates interference, atmospheric changes, transmission system issues (such as problems with cables, connectors, or antennas), or possibly radio hardware problems.

This is shown as a percentage of the interface configuration (that is, if your interface is set for 100BaseT, then 100% represents 100Mbps. Compare offered load (inbound) to delivered load (outbound) to determine if radio capacity is a bottleneck for the data transfer. This chart can illustrate inbound and/or outbound utilization, and uses different colors for data entry. The legend can be hidden.Figure 38 Ethernet Utilization pageNote that outbound utilization never exceeds the rate where a radio is configured. For example, if the radio is configured for a 55 Mbps capacity, outbound utilization will never exceed 55 Mbps at 100BaseT.The Ethernet Utilization Watermark level function allows administrators to receive an SNMP trap when watermark conditions are exceeded. For example, if a radio is configured for 55 Mbps capacity, the administrator may wish to be warned if the radio exceeds 50 Mbps for more than 1 hour per day. In this case, set the Watermark level to 50% and the trap duration to 60 minutes. Traps must be enabled to activate this function.When the watermark level function is enabled, a line on the chart appears for data comparison to the watermark.

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios74 209866-0022015-09-09TroubleshootingThis section provides information regarding troubleshooting of common issues and alarms on these radios. Exalt Digital Microwave Radio systems are designed by Exalt’s expert engineers with extensive experience through multiple generations of microwave radio design. These new-generation systems contain extensive diagnostic tools, alarm indications, and troubleshooting aids. And, as compared to other systems in their class, are easier to install, maintain, and troubleshoot. The GUI provides information to aid in troubleshooting (see Diagnostic Charts Page).Contact Exalt Customer Care for further assistance with issues with your Exalt radio and with suggestions on how the radio and documentation can be improved.General PracticesTroubleshooting a microwave radio link can be a complex task. Approach troubleshooting as a process of elimination, and first determine which portions of the system are operating properly.In a vast majority of cases, failures or poor performance of microwave links is attributed to something other than the microwave radio hardware. In this respect, the back-to-back bench test (see Back-to-back Bench Testing) is very important to determine if radio hardware is operating properly and eliminate many variables in the troubleshooting process.If a back-to-back bench test fails, then the radio hardware is either broken or the radios are improperly configured. Upgrade the radio to the most current release of firmware, and/or reset the radio to its critical factory settings, following the quick start guide instructions and those in Configuration and Management, helps to confirm if configuration issues cause failure. The most common issues with microwave radio links are:• An improperly terminated antenna or transmission system• Multipath propagation• RF interference• Path obstruction• Misaligned antenna• Faulty antenna• Improper grounding• Insufficient link margin in the design/implementation• Moisture in the transmission system (antenna feed and/or waveguide)If the radio link has been operating without issues and is exhibiting new poor performance behavior or becomes completely inoperative, the troubleshooting process should pay close attention to any conditions that may have changed between the time when the system was working without issue and the time when the issues started. Also, it can be helpful to compare some performance parameters of the system before and after the presence of issues. Often the source of the issues can be determined by thoughtful consideration of changes, such as:• Changes in weather, including high winds• Changes made to the radio equipment, transmission system, or connected equipment• New radio systems or electronic equipment the nearby radio or transmission system

Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios209866-002 752015-09-09• New construction nearby either end of the link, or along the path• Tree growth, flooded fields, or changes in rivers/lakes along the pathVerify that configurations are set as follows:• Frequency pair matches (oppositely) at each end of the link• Bandwidth matches at each end of the link• Ethernet interfaces are enabled, as desired• Link security key matches at each end of the link• Firmware version matches at both endsTypical Indications of IssuesIn many cases, microwave radio users do not notice changes or degradation to the radio system until the radio system fails completely or becomes highly errored or significantly intermittent. However, regular management of the radio system can help indicate changes in performance that have not yet impacted user performance, but may impact performance at a later date if left unchecked or unaddressed. The administrator can use this as an opportunity to be proactive and monitor the radio link performance regularly, watching for unexplained or unexpected changes in performance and trends in performance changes.Most importantly, monitoring radio system RSL over time indicates the performance of the radio system. Address any long-term drop in RSL and erratic or unsteady RSL. Some RSL changes are expected and weather patterns and the related multipath can cause dramatic RSL changes resulting in system outage. However, that outage should not occur at a significantly greater rate than the designed long-term performance. Consult the path design engineer for more information about link reliability expectations and anticipated RSL deviation.In addition, regular inspection of the transmission system (RF cables and antennas) and paying close attention to changes along the path, such as construction or tree height, or new microwave radio installations nearby, can be extremely helpful and proactive.When link performance is very poor, alarms on the radio front panel and within the radio’s management system indicates particular failures. Consult this manual for more information on the specific alarms and diagnostics, or contact Exalt Customer Care for assistance. Exalt Customer Care is primarily motivated to determine if the radio hardware is faulty and require return for repair, and to help execute an effective and efficient repair and return process for radio terminals believed to be faulty. However, Exalt Customer Care provides advice regarding the total radio system and RF path engineering and environment, and advises on troubleshooting. End users should first contact the installer and/or designer of the system. In many cases, an in-depth understanding of RF design is required, and on-site analysis and special test equipment, may be necessary. Compared to phone support from Exalt Customer Care, troubleshooting is much more expeditious if the professional installer and/or link designer examines the system and reviews the management information in the GUI. In turn, if the professional installer and/or link designer contacts Exalt Customer Care, the process to rectify the system is much more expedient due to the in-depth knowledge related to the implementation and the RF environment.Improper Transmission SystemImproper transmission system is a very common problem. In many cases, this is a problem that occurs during installation and is not a problem that suddenly appears. However, if waveguides are moved or

$Exalt Installation and Management GuideExtendAir G2 24GHz Digital Microwave Radios76 209866-0022015-09-09flexed and radio errors, changes in RSL or other performance issues occur, this is a certain sign of this issue. Another relatively easy method to test for this condition is to decrease the output power of the radio system (at each end, one end at a time). Poor RF termination may be reflecting too much RF energy back into the radio system, and reducing output power reduces the reflected energy at a faster rate than the transmitted energy towards the far end. Be careful not to reduce the output power to the point where the radio’s threshold is reached. Typically, a reduction of just 3 to 6dB is enough to determine if this is the issue. If the reduction of output power clears the error condition, this is the likely cause.Use a reflectometer or meter that can read VSWR at the operating frequency to identify poor terminations as well as poor antenna feeds.Multipath PropagationMultipath propagation is a term that encompasses changes to the RF path, such as reflections and/or refraction, causing partial or complete destruction of the radio signal, and thus excessive bit errors and/or system outages. Rapid changes in temperature, inversion layers, humidity, air pressure, water evaporation, as well as standing water or moisture on objects along the path are all examples of changes that can cause multipath propagation. New building construction near either end of the path or along the path can cause new reflection characteristics.If your system has been operating without issue and is suddenly experiencing issues that are symptomatic of a certain time of day or related to change in climatic events or some of the external factors listed above, this is likely the cause. Consult a professional RF path engineer in these cases. Often, minor repositioning of the antennas at either or both ends can reduce or eliminate these problems.RF InterferenceRF interference is usually indicative of another radio system nearby either end of your radio system or aimed towards one or both ends of your radio system – usually at or near the same frequency and usually with a similar signal level. This is less common for licensed systems, but still can occur.Other forms of RF interference also exist, such as electronic equipment placed close to the radio chassis or transmitters that couple onto the cabling or grounding system of the radio. Microwave ovens and wireless communication devices used near the equipment or cabling are examples of electronic equipment interference.RF interference, like most other causes of problems, is indicated by significant bit errors and/or system outages.One means to determine presence of interference is the use of a spectrum analyzer that covers the same range as the radio system. A professional RF engineer can use a spectrum analyzer to locate sources of interference, measure these sources, and determine potential remedies to take to operate in the presence of interference.If a spectrum analyzer is not available, the radio’s RSL port can help determine RSL levels of interfering signals. By turning the far-end radio off, the residual RSL measured by the radio indicates the level of interference seen by the radio. It is possible that interference levels below that which can be measured still have an impact on the radio system – especially if the radio system has low fade margin or is using a high order modulation.$
