02030311-07 Airspan Networks Inc. 1-1 Overview This chapter provides a brief overview of the ASWipLL system. 1.1. Introduction Airspan’s ASWipLL system provides a low-cost, high-performance point-to-multipoint IP-based Broadband Fixed Wireless (BFW) Access solution. ASWipLL provides wireless local-loop (last-mile) connectivity designed to deliver high-speed data, Voice over IP (VoIP), and multimedia services to residential, SOHO (small office/home office), and SME (small medium enterprise). ASWipLL offers service providers an integrated access solution, providing quick-to-market deployment and low-market entry cost for broadband services. ASWipLL operates in the licensed band (700 MHz, 925 MHz, 1.5 GHz, 2.3 GHz, 2.5 GHz Multichannel Multipoint Distribution Services - MMDS, 2.8 GHz, and 3.x GHz - ranging from 3.3 to 3.8 GHz), and unlicensed band (900 MHz, 2.4 GHz ISM, and 5.8 GHz). Each ASWipLL Base Station, at maximum configuration, supports up to 3,024 subscribers, providing connectivity speeds of up to 4 Mbps. ASWipLL enables interconnection with the Public Switched Telephone Network (PSTN) by the use of an IP-to-PSTN gateway. ASWipLL provides VoIP by its interoperability with a wide range of third-party products such as residential gateways (RGW), access gateways, gatekeepers, and softswitches. 1
Overview Hardware Installation Guide 1-2 Airspan Networks Inc. 02030311-07 ASWipLL utilizes air protocol technology for wireless packet switching using Frequency Hopping technology. ASWipLL's in-house Preemptive Polling Multiple Access (PPMA) Air MAC protocol technology, which recognizes transmission type and allocates bandwidth, is highly efficient—80% throughput (e.g. 80% of 4 Mbps = 3.2 Mbps net capacity)—allowing multiple concurrent subscribers to utilize bandwidth. ASWipLL provides bandwidth management by supporting both asymmetric and aggregated Committed Information Rate (CIR) and Maximum Information Rate (MIR), guaranteeing bandwidth levels to subscribers. In asymmetric CIR/MIR, different values are defined for uplink and downlink traffic: in aggregated CIR/MIR, values are defined as the sum of the uplink and downlink traffic. ASWipLL supports VLANs and VPNs based on IEEE 802.1Q/p. ASWipLL supports IP routing and PPPoE bridging, as well as transparent bridging. ASWipLL provides embedded security features such as IP (packet) filtering based on addresses, protocols, and applications. The ASWipLL system provides SNMP-based management, allowing remote and local management, configuration, and monitoring of ASWipLL equipment. 1.2. System Architecture The ASWipLL system architecture is composed of the following three basic areas:  Base Station site: consists of ASWipLL access units that interface between the provider’s backbone and the ASWipLL subscriber sites.  Subscriber site: consists of ASWipLL customer premises equipment (CPE) that interfaces between the Base Station and the subscriber’s network.  Network management tools: consists mainly of Windows- and SNMP-based programs, providing fault, configuration, performance, and security management for the ASWipLL system.

Overview Hardware Installation Guide 1-4 Airspan Networks Inc. 02030311-07 1.3. Base Station Units The ASWipLL Base Station interfaces between the subscriber sites and the service provider's backbone, providing subscribers with high-speed data, Internet, and VoIP services. The ASWipLL system provides various devices (some optional) for the Base Station site. The implementation of these devices depends on the desired network (e.g. point-to-point radio link), number of outdoor radios and power source at the Base Station, and required synchronization type (i.e. by GPS). Figure 1-2 shows a fully populated ASWipLL Base Station at maximum configuration (24 BSRs, 4 BSDUs, 1 BSPS, and a GPS).

Hardware Installation Guide Overview 02030311-07 Airspan Networks Inc. 1-5 1.3.1. Base Station Radio (BSR) The BSR is an outdoor radio unit, typically mounted on a pole or wall, involved in providing a wireless link between the Base Station and subscribers. The standard BSR provides 60-degree radio coverage, serving up to 126 subscribers in a sector. The BSR is available in the following models: ! BSR with a built-in antenna ! BSR with one N-type port for connecting an optional third-party external antenna ! BSR with two N-type ports for connecting two optional third-party external antennas for dual antenna diversity For Base Stations consisting of multiple BSRs, the BSRs are powered, and interface with the provider’s backbone by the ASWipLL Base Station Distribution Unit (BSDU). For a Base Station consisting of a single BSR, the BSR is typically powered and connected to the provider’s backbone by the ASWipLL Subscriber Data Adapter (SDA). 1.3.2. Point-to-Point Radio (PPR) The PPR device is similar to the BSR, but implemented in a point-to-point radio configuration, providing wireless communication with a single remote subscriber ASWipLL radio unit (i.e. SPR or IDR).
Overview Hardware Installation Guide 1-6 Airspan Networks Inc. 02030311-07 1.3.3. Base Station Distribution Unit (BSDU) The BSDU is an Ethernet switch implemented at Base Stations consisting of multiple BSRs. The BSDU provides 100Base-T interface between the BSRs and the provider's backbone. The BSDU is also responsible for providing BSRs with –48 VDC power supply and frequency hop synchronization between BSDUs, BSRs, and Base Stations (when a GPS is implemented). The BSDU is installed indoors in a standard 19-inch cabinet, and connects to the BSRs by standard CAT-5 cables. Each BSDU can connect to a maximum of six BSRs. In addition, up to four BSDUs can be daisy-chained to support a maximum of 24 BSRs. Therefore, a Base Station at maximum configuration can serve up to 3,024 subscribers. Note: At a Base Station consisting of a single BSR, the BSR typicallyinterfaces with the provider's backhaul through the SDA instead of the BSDU.(See Section 1.4.1, "Outdoor Radio (SPR) with Indoor Switch/Hub"). 1.3.4. SDA-1/48V The SDA-1/48V is a compact indoor adapter, especially designed for use when available power source is 48VDC (i.e. no AC power supply), and when no synchronization is required (i.e. in licensed bands). The SDA-1/48V provides the BSR with Ethernet connectivity to the backhaul. 1.3.5. Global Positioning System (GPS) - Optional The GPS antenna is a rugged, self-contained GPS receiver and antenna that receives a universal GPS satellite clock signal. The GPS is an optional unit that connects to the BSDU. The GPS synchronizes frequency hopping of multiple Base Stations, ensuring that the entire ASWipLL network operates with the same clock based on a universal satellite clock signal, and, thereby, eliminating radio frequency ghosting effects.
Hardware Installation Guide Overview 02030311-07 Airspan Networks Inc. 1-7 1.3.6. Base Station Power Supply (BSPS) - Optional The BSPS is an optional third-party unit that is implemented at Base Stations to provide –48 VDC power supply and power redundancy. The BSPS is installed in a standard 19-inch cabinet and connected to the BSDU. The BSPS provides the BSDUs and BSRs with the following: ! Power supply of –48 VDC. ! Power redundancy in case of power failure. The BSPS charges a battery bank that provides this power redundancy during mains failure. Thus, the BSPS acts as a DC-uninterruptible power supply (UPS) with a battery connected to it. The size of the battery determines the backup and charging time. Since the system is current limited, the maximum battery size is based on that limit. ! Remote power management and monitoring (by ASWipLL’s WipManage program). The BSPS consists of the following basic components: ! Main unit: ! DC Rectifier modules: converts AC current to DC. The BSPS can house up to four rectifiers. The rectifiers are “hot plugged” and operate in parallel. This enables the user to define an N+1or N+2 redundant system. Each rectifier has its own current sharing system, satisfying a complete sharing among rectifiers. ! System controller: provides BSPS management control and BSPS operating information. ! Electronic Low Voltage Detector (ELVD): disconnects the battery from the load, avoiding damage to the battery when over-discharged. ! Load and battery circuit breakers: provide DC protection and distribution. ! DC Distribution unit: provides circuit breakers for distributing the output current to multiple BSDUs. It also contains a bypass switch to bypass the LVD. ! Battery: provides the BSPS system with back-up power.
Overview Hardware Installation Guide 1-8 Airspan Networks Inc. 02030311-07 1.4. Subscriber Site Units The ASWipLL subscriber units are located at the subscriber's premises. The ASWipLL subscriber site consists of a radio transceiver that receives and transmits signals from and to the Base Station. The radio transceiver provides the subscriber with high-speed data access, Internet access, and VoIP at up to 4 Mbps. The ASWipLL radios interface with the subscriber's Ethernet network either through a hub or switch, or directly, depending on ASWipLL radio model. Note: For VoIP support, Airspan can provide a third-party residential gateway (RGW). The RGW typically provides two POTS ports for telephony, a 10BaseTLAN port for subscriber PC/network, and a 10BaseT port for connecting to theSDA or IDR (depending on subscriber site configuration). The ASWipLL system provides two different subscriber site configurations: ! Outdoor radio (i.e. SPR) with indoor Ethernet switch/hub (i.e. SDA) ! Indoor radio only (i.e. IDR device) 1.4.1. Outdoor Radio (SPR) with Indoor Switch/Hub (SDA) The outdoor radio with indoor Ethernet switch/hub configuration consists of the ASWipLL Subscriber Premises Radio (SPR) and the ASWipLL Subscriber Data Adapter (SDA), respectively. 1.4.1.1. Subscriber Premises Radio (SPR) The SPR is an outdoor radio transceiver that provides a wireless link between the subscriber’s network and the Base Station. The SPR connects to the subscriber’s network through the SDA Ethernet hub/ switch. The SDA provides the SPR with DC power, lightening protection, and Ethernet (10Base-T and/or 100Base-T) interface with the subscriber’s PCs/network (up to four PCs depending on SDA model).
Hardware Installation Guide Overview 02030311-07 Airspan Networks Inc. 1-9 The SPR is mounted outside on an external wall or on a pole. The SPR connects to the SDA by a standard CAT-5 cable. The SPR is available in the following basic models:  SPR with Standard Gain Antenna: includes a built-in antenna with 15-dBi antenna gain, covering an area of 23 degrees.  SPR with High-Gain Antenna: includes a built-in antenna with 18-dBi antenna gain, covering 15 degrees.  SPR with External Antenna: includes an N-type connector port for attaching a third-party external antenna. 1.4.1.2. Subscriber Data Adapter (SDA) The SDA is a switch or hub (depending on model), providing the SPR with -48 VDC power supply, lightening protection, and 10/100BaseT interface to the subscriber’s PCs/network. The SDA is installed indoors and can be mounted on a wall or simply placed on a desktop. The SDA connects to the SPR by a standard CAT-5 cable. The SDA is available in the following models:  SDA-1: hub providing one 10BaseT interface with the subscriber’s computer (or LAN network if connected to another hub or a switch).  SDA-1/DC: adapter that provides Ethernet (one 10BaseT) and regulated –48 VDC power to the SPR. This model can be powered from a voltage of 10 – 52 VDC (e.g. from a solar panel that typically provides 12 VDC). This model is typically implemented in mobile wireless applications, e.g. in a car or truck. (This model can also be implemented at a Base Station with a BSR.)  SDA-4H: hub providing four 10BaseT interfaces with the subscriber’s computers and/or networks. One of the 10BaseT ports provides crossover cabling for interfacing with another hub or LAN switch. Alternatively, it may be connected to another PC via a crossed Ethernet cable.
Overview Hardware Installation Guide 1-10 Airspan Networks Inc. 02030311-07 ! SDA-4S: integrated LAN switch, providing four 10/100BaseT interfaces with the subscriber’s PCs/network. The ports of the SDA-4S models support Auto Negotiation, allowing automatic configuration for the highest possible speed link: 10BaseT or 100BaseT, and Full Duplex or Half Duplex mode. In other words, the speed of the connected device (e.g. a PC) determines the speed at which packets are transmitted through the SDA-4S port. For example, if the device to which the port is connected is running at 100 Mbps, the port connection will transmit packets at 100 Mbps. If the device to which the port is connected is running at 10 Mbps, the port connection will transmit packets at 10 Mbps. The SDA-4S ports also support automatic MDI/MDI-X crossover detection, allowing connection of straight-through or crossover CAT-5 cables to any port. The SDA-4S is available in the following models: ! SDA-4S (standard): standard integrated LAN switch, providing four 10/100BaseT interfaces with the subscriber’s computers. This model is ideal for SOHO implementation. ! SDA-4S/VL: provides VLANs between ports and the SPR, ensuring privacy between LAN users of the different ports. For example, all users connected to Port 1 do not “see” users connected to Port 2. This model is ideal for multi-tenant (VLAN security) implementation. ! SDA-4S/VLtag: ideal for multi-tenant applications where traffic engineering and privacy is required. SDA-4S/VLtag assigns a specific VLAN ID to traffic, based on the SDA-4S/Vltag port at which the traffic arrives. The VLAN IDs are fixed (since SDA-4S/VLtag is not user configurable). SPR converts the four VLAN IDs tagged by SDA-4S/VLtag to four VLAN IDs configured through ASWipLL’s network management system (WipManage). The tag conversion is performed by SPR before sending the traffic to the air (i.e. to the BSR) and vice versa when coming from the air.
Hardware Installation Guide Overview 02030311-07 Airspan Networks Inc. 1-11 ! SDA-4S/1H3L: provides a high priority port (left-most port) for VoIP traffic. ! SDA-4S/VL/1H3L: combines the functionality of the SDA-4S/VL and SDA-4S/1H3L models (i.e. VLAN for each port and a high priority port for VoIP). Figure 1-3 displays a typical subscriber site setup implementing an SPR and SDA. Figure 1-3: Subscriber site with SPR and SDA units (optional RGW)
Overview Hardware Installation Guide 1-12 Airspan Networks Inc. 02030311-07 1.4.2. Indoor Radio Unit (IDR) Only The indoor radio unit configuration consists of the ASWipLL Indoor Data Radio (IDR). The IDR combines the functionality of the SPR and SDA, functioning as a transceiver and a hub. The IDR provides one 10BaseT Ethernet interface to the subscriber's network. The IDR receives its power from a separate power supply unit (AC-DC power adapter). The IDR is available in two models: ! IDR with a built-in internal antenna ! IDR with a TNC connector for attaching a third-party external antenna The IDR with a built-in antenna is typically mounted on an interior wall or on a desktop with line-of-site with the Base Station. The antenna of the IDR model with an external antenna is typically mounted outdoors to provide line-of-site with the Base Station. The IDR can be used for data and voice transmissions. In the case of voice, the IDR uses a third-party RGW to interface with the subscriber’s IP phone. Figure 1-4 displays a typical setup for data and voice at a subscriber site implementing the IDR. Figure 1-4: Subscriber site with IDR and third-party external antenna (optional RGW)

Safety Guidelines Hardware Installation Guide 2-2 Airspan Networks Inc. 02030311-07 2.1. ASWipLL Radios and Third-Party External Antennas Warning: Do not connect and disconnect antennas while the power is on. Thiscan cause irreversible device damage. Warning: The digital portion of the transceiver has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment on and off, the user is encouraged to try correct the interference by performing one or more of the following measures: - Reorientate or relocate the receiving antenna - Increase separation between the equipment and receiver - Connect the equipment to an outlet on a circuit different from that to which the receiver is connected - Consult the dealer or an experienced radio/TV technician for help Warnings: 1) The device cannot be sold retail, to the general public or by mail order. It must be sold to dealers. 2) Installation must be controlled. 3) Installation must be performed by licensed professionals. 4) Installation requires special training. Warning: The ASWipLL radio devices and antennas should be installed ONLY by experienced installation professionals who are familiar with localbuilding and safety codes and, wherever applicable, are licensed by theappropriate government regulatory authorities. Failure to do so may voidAirspan’s ASWipLL product warranty and may expose the end user or theservice provider to legal and financial liabilities. Airspan and its resellers ordistributors are not liable for injury, damage or violation of regulationsassociated with the installation of outdoor units or antennas.
Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-3 Warning: For unlicensed bands, it is the responsibility of the person installing the ASWipLL system to ensure that when using the outdoor antenna kits in theUnited States (or where FCC rules apply), that only those antennas certified with the product are used. The use of any antenna other than those certifiedwith the product is expressly forbidden in accordance with FCC rules CFR47 part 15.204. The installer should configure the output power level of antennasaccording to country regulations and per antenna type. Warning: For unlicensed bands, in accordance with FCC regulations, ensure that the external antennas provide an EIRP of less than or equal to 36 dBm to prevent interference with other radios operating in the unlicensed band. The EIRP is defined by the following formula: Max. Power Output + Antenna Gain - Cable Loss ≤≤≤≤ 36 dBm (EIRP) Airspan does not supply cables for connecting external antennas. It is the responsibility of the installer to provide the cable and ensure the cable characteristics (e.g. length and cable loss) enables adherence to FCC's regulations concerning maximum EIRP. The table below lists examples of cable loss per cable (not supplied by Airspan) for maximum antenna gains, based on the formula above. Note that the EIRP is either equal to or less than 36 dBm. Warning: The ASWipLL transceivers emit microwave radiation. Therefore, a minimum distance must be maintained from the front of the ASWipLL radios: - Unlicensed bands (e.g. 5.8 GHz): 200 mm - Licensed bands: - 700 MHz (i.e. ASWipLL 700) = 800 mm - 2.5 GHz (i.e. ASWipLL 2.5) = 500 mm
Safety Guidelines Hardware Installation Guide 2-4 Airspan Networks Inc. 02030311-07 Warning: To avoid RF interference between BSRs operating in the 700 MHz where four BSRs are installed at a Base Station, a 1-meter separation must be provided between the BSRs' antennas operating in the lower frequencies (i.e. 711.5 and 714.5 for 1 Msps mode; 712 and 714 for 1.33 Msps mode) and the BSRs' antennas operating in the upper frequencies (i.e. 741.5 and 744.5 for 1 Msps mode; 742 and 744 for 1.33 Msps mode). Warning: When using external antennas, the external antennas must not beco-located or operating in conjunction with any other antenna or transmitter. Warning: ASWipLL radios using an external antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. Warning: Inherent risks exist in operating equipment in license-exempt bands (i.e. 900 MHz). Airspan recommends that you do not purchase or deploy any equipment that operates in license-exempt bands without first analyzing the interference environment at each of your proposed deployment locations. Please contact your Authorized Airspan System Integrator or Distributor if you have any questions or require assistance regarding interference analysis. Airspan Networks will not be held responsible for product performance issues related to interference. Warning: In environments that produce disturbances such as paging systems, Airspan recommends using a narrow-band cavity filter and implementing the appropriate frequency bands (within the filter's capabilities), i.e. building an NVRAM frequency table using only these frequencies. Warning: Mount outdoor radios so that their front panel ports face down to prevent water from settling on the ports. This avoids damage to the units such as corrosion and electrical short-circuiting. Warning: Do not mount outdoor radios and external antennas in weathersuch as rain or lightening that may increase risk of electrocution.
Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-5 2.2. Electrical Safety Guidelines Warning: Connect the power only after all network and antenna cableconnections are performed. Powering the device before connecting, forexample, the external antenna, can lead to irreversible device damage. Warning: To prevent short-circuiting and electrical shocks, cables with exposed ends (i.e. not yet crimped) should be covered with protectivepolythene bags during external cable installation processes. 2.2.1. Handling Electrostatic Devices Warning: To prevent ESD damage to ASWipLL devices, always wear an ESD wrist strap when handling these devices or coming into contact with internalcomponents. Electrostatic devices are those devices that may be damaged by the inadvertent discharge of static electricity from a charged body. The risk of damage, due to electrostatic discharge (ESD) to a device, may cause the device to fail suddenly, or it may induce a partial defect within the device, which will cause subsequent premature failure. Static electricity can result from operators walking on floors, moving around on chairs, from the movement of operator's clothing or even casual brushing against racks, benches or walls. Airspan recommends the following guidelines to be adopted to minimize the risk of component failure due to electrostatic discharge to the device: ! ASWipLL devices are provided typically in see-through anti-static bags. Wherever possible, checking and inspection of a unit should occur without removing it from the bag. ! All operators shall wear the approved conductive overall. ! Where operators come into direct contact with any piece of electronic hardware, operators must wear an ESD-preventive wrist strap. All straps and cords should be tested using a Wrist Strap Tester prior to use. The wrist strap cords shall have a 2 Meg Ohm resistor fitted at either end. Wrist straps should be worn in direct contact with bare skin and not over clothing.
Safety Guidelines Hardware Installation Guide 2-6 Airspan Networks Inc. 02030311-07 2.2.2. Grounding Only certain ASWipLL devices require additional grounding. ASWipLL devices that do not require additional grounding have grounding at the main supply outlet. The following table lists the ASWipLL devices’ grounding requirements. Table 2-1: ASWipLL grounding requirements Site ASWipLL device Grounding BSR Through the mains (via BSDU) i.e. no additional grounding required BSDU Additional grounding required (grounding lug at rear end of chassis) Base Station BSPS Additional grounding required (grounding lug at rear end of chassis) SPR Through the mains (via SDA), i.e. no additional grounding required CPE IDR Through the mains, i.e. no additional grounding required 2.2.3. Lightening Protection Warning: Never install the equipment during stormy weather and lightening. ASWipLL devices comply with the Surge Immunity standard: EN 61000-4-5. ASWipLL devices are protected from lightening surges as the outdoor devices (BSRs and SPRs) are encased in a plastic chassis. Therefore, if lightening strikes the device, an electrical circuit cannot be completed, and hence, no electrical surge can occur. In addition, ASWipLL outdoor and indoor (SDA) devices provide high-speed data line protection against direct and induced transient over-voltages surges on the cables. This capability is provided by the fact that all ASWipLL devices are designed with TVS (transient voltage suppressor) components that maintain potential differences.
Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-7 However, for geographical areas that have above normal lightening activity, Airspan can supply a surge protector composed of a 15-pin D-type adapter with a grounding wire. 2.3. Cabling Warning: The maximum cable length between the radio transmitters (i.e. BSR and SPR) and terminating equipment is 100 meters. Warning: Cables with exposed ends (i.e. not yet crimped) should be coveredwith protective polythene bags during external cable installation processes. Warning: Prior to the commencement of any installation, commissioning workat ‘live’ sites it is the responsibility of the Airspan engineer to advise thecustomers representative before any activity commences. If in doubt assume equipment is ‘live’. Warning: Disturbance of cables on an In-Service exchange can cause loss of service. Extreme care must be taken when installing cables at any customer orsubscriber premises. 2.3.1. Considerations The following issues should be considered during cabling at the ASWipLL Base Station and customer premises: ! Cable routes are to be defined in the site-specific documentation. Note: A minimum separation of 200 mm should exist between power and datacables. However, it is permissible to allow these cables to cross each other at right angles. ! Observe recommended minimum bend radii when installing copper cables. Wherever a cable changes direction, ensure that it does so in a smooth curve with a radius of at least 50 mm to prevent damage.
Safety Guidelines Hardware Installation Guide 2-8 Airspan Networks Inc. 02030311-07 ! Plastic ties and wraps are to be used to secure cables at regular intervals to trays, guides, and mounting pole/bracket. Ensure all trimmed ends are disposed of safely and at regular intervals. ! Data cables of less than 20 pairs shall be mixed in bundles not exceeding 50 mm in diameter. ! Ensure cables are not trapped in cabinet doors, by slide-in equipment or support metalwork. ! Excessive stress on cable terminations caused by taught cables should be avoided. Connector strain relief, if not built into the connector used, shall be provided by means of a strategically located cable tie. A maintenance loop or a generous amount of cable slack shall be provided just before the cable reaches the ASWipLL device to allow for equipment removal without disturbance to adjacent cables. ! When installing network cables, ensure they are not damaged by friction or sharp edges. ! Data cables providing connection to the customers network shall be run in protective conduits. Cable conduits should be secured to the wall in accordance with manufacturers instructions. ! External data cables are to be protected in metal conduits, which are to be secured to the building structure in accordance with manufacturers recommendations. ! Wiring conduits must be placed in areas to prevent a trip hazard (e.g. don’t install on roof walkways) ! Cables should be carefully fed through conduits and not pulled by means of any attached connector. ! Sufficient space should be provided in cable conduits, trunking or trays (where possible) to allow for future cabling growth. ! Data cables threaded into holes drilled in walls are to be covered by a waterproof sheath to prevent water penetration.
Hardware Installation Guide Safety Guidelines 02030311-07 Airspan Networks Inc. 2-9 ! Silicone sealant should be used to plug any holes on both internal and external wall surfaces once cables are in place. ! Cables not housed in conduits must be placed in a manner to avoid a trip hazard. (Avoid trailing wires across passageways.) 2.3.2. Labeling The following labels are required to be fitted to ASWipLL equipment: ! Voltage Warning ! High Earth Leakage Current ! Signal Cable Designation 2.3.2.1. Voltage Warning Warning: Voltages over 30 Volts AC and 50 Volts DC are categorized ashazardous. Hazard warning labels should be fitted where required. Certaincountries require equipment warning and instruction labels to appear in thelocal language. When installing ASWipLL equipment ensure that localrequirements regarding labels are given consideration. ! Where mains power is fed from separate phases, appropriate warning labels must be fitted to warn of the increased danger. ! The AC equipment used in the BSPS cabinet must carry a relevant voltage warning label specific to the country in which it is being installed. The label will be fitted to the cabinet doors displaying an electrical hazard symbol, the local operating voltage and the letters ‘AC’. ! A power feed identification label (e.g. PWR ‘A’) shall be applied in the following locations: ! On the rear of the main power rack adjacent to the terminal block !
