(SOC), with a pole/roof (wall) mounted radio system and antennae. This high performance chip can support up to 28 + 28 MHz channels (full duplex) forms part of the AS.MAX portfolio of WiMAX network infrastructure equipment. It is compatible with the Airspan EasyST and ProST subscriber terminals and other manufacturer's CPEs that are fully WiMAX compliant. The MicroMAX BSR is an outdoor radio that is mounted outside on a pole or wall. The BSR provides a wireless link with subscribers and interfaces with the provider's backbone. The MicroMAX BSR is available in two models. These models differ by antenna design (providing integral flat-panel antennas, or an N-type port for attaching third-party external antennas). MicroMAX BSR is available in numerous frequency bands, operating in FDD and TDD modes in numerous channels, see:

MicroMAX Frequency Ranges. The BSR connects to the indoor Ethernet switch by a CAT-5e cable, which carries the Ethernet signal, and DC power. For a MicroMAX Base Station consisting of multiple BSRs, there are two (2) options. The BSRs can be connected to individual Subscriber Data Adapters (SDA-4S) or to Base Station Distribution Units (BSDU). For a Base Station consisting of a single BSR, the BSR typically connects to a single Subscriber Data Adapter (SDA-4S or SDA-4SDC). MicroMAX BSR provides a low cost, high-performance point-to multipoint packet-based Broadband Wireless Access (BWA) solution. MicroMAX BSR Provides wireless connectivity designed to deliver high-speed data, voice over IP (VoIP) and multimedia services to residential, SOHO (Small Office/Home Office), and SME (Small to Medium Enterprises). The MicroMAX is an encased outdoor radio providing access to the MicroMAX's communication ports on its bottom panel. The MicroMAX's back panel provides holes for mounting. MicroMAX BSR interfaces with the service provider's backbone through either:

The SDA-4S Type II or the SDA-4SDC (referred henceforth as SDA-4S) integrated LAN switches. o SDA-4S Type II: integrated LAN switch, providing power and four 10/100BaseT ports for interfacing with the subscribers network o SDA-4SDC Type II: integrated LAN switch, providing power and four 10/100BaseT interfaces and especially designed for implementation where available power supply is DC (10 to 52 VDC), e.g. from a solar panel. This model provides regulated 48 VDC power to the BSR. Base Station Distribution Unit (BSDU) - provides an interface between multiple BSRs and the service provider's backbone. MicroMAX can be managed by an SNMP-based network management system (Netspan) using standard and proprietary MIBs. In addition, external third-party management systems such as HP OpenView can also manage the MicroMAX using these MIBs. Basic management can be performed using any standard Web browser. Note; for management refer to MicroMAX Web Management documentation. 8 System Overview MicroMAX Frequency Ranges The table below lists the frequency range of MicroMAX models currently available.

A summary of the main site planning considerations is provided below:

Minimum obstructions (e.g. buildings) in the radio path between base station and the subscriber terminals Mount radio as high as possible to avoid obstructions in the wireless path Check possibility of future obstructions such as plans to erect buildings and trees that may grow tall enough to obstruct the wireless path Align radio for maximizing received signal strength (RSS) Consider nearby sources of interference that could degrade performance of radio Mount radio as far from sources of interference as possible Ensure base station and subscriber terminals (i.e ProST/EasyST) are within maximum coverage range of reception Maximum standard CAT-5e cable length connecting the MicroMAX to the indoor SDA-4S or BSDU is 100 meters Ensure that you have sufficient wiring conduit and cable ties to channel and protect the CAT 5e cable connecting the outdoor MicroMAX to the indoor SDA-4S Radio Antenna Alignment ProST Once the subscriber unit (i.e. ProST) is installed and aimed in the general direction of the BSR, it is recommended to measure the received signal strength (RSS) to determine the signal strength received from the BSR, and to precisely align the ProST for maximum signal strength. You need to orientate (up/down, left/right) the ProST until the maximum RSSI levels are achieved, and then secure the ProST. EasyST Once the subscriber unit (i.e. EasyST) is installed and aimed in the general direction of the BSR, simply move the EasyST to the position that gives optimal reception. 13 PHYSICAL DESCRIPTION This section provides a description of the components of the MicroMAX installation:

The third-party external AC/DC Power Converter is an optional unit that connects to the BSDU in the event there is no -48VDC availability at the Base Station site. The AC/DC Power Converter chassis fitted with one PS Unit for BSDU (PC-BSDU-1) supports up to 8 BSRs. An additional PS unit is available (optional) for redundancy. The figure below illustrates the AC/DC Power Converter's physical dimensions. AC/DC Power Converter Physical Dimensions The AC/DC power converter physical dimensions are described in the following table. Parameter Value Comment Height 43.2 mm (1.7 inches) Width 482.6 mm (19 inches) The physical dimensions exclude the bracket flanges for mounting. Depth 228.6 mm (9 inches) Redundant PS Unit The RPSU-BSDU-1 is a redundant PS Unit for the BSDU AC/DC power converter. The power factor corrected (PFC) front ends provide a 48 VDC output for distributed power applications. The small 1U by 2U size allows for configurations of either height in hot-swap redundant systems while its internal fan and cooling design permits wide use with reliable operation. The figure below illustrates the redundant PS Unit. 27 MOUNTING THE BASE STATION RADIO (BSR) Mounting the MicroMAX The MicroMAX BSR can be pole-mounted or wall-mounted (optional). Pole mounting allows the BSR to be easily adjusted in the horizontal (azimuth) and vertical (elevation) planes for antenna alignment. For either mounting method, the MicroMAX provides mounting holes (displayed in the figure below), molded into its back panel for attaching the mounting brackets. Note: The BSR fully complies with IP Code - IPX6 for product enclosure protection. Warning: The BSR device is an outdoor radio unit, and therefore, must only be mounted outside. Warning: Mount the MicroMAX in an orientation such that its ports (located on the bottom panel) faces downwards. This prevents rain water from settling on the ports, and thereby, avoiding damage to the unit such as corrosion and electrical short-circuiting. Note: The standard BSR kit, provides pole-mounting brackets. If you want to wall-mount the MicroMAX, contact your Airspan distributor for pricing and ordering of wall-mounting brackets. Pole-Mounting the BSR Pole mounting allows the MicroMAX to be easily adjusted in the horizontal (azimuth) and vertical

(elevation) planes for antenna alignment. The BSR is mounted using the mounting holes located on the BSR's back panel and the supplied pole-mounting brackets. The pole-mounting bracket is designed to support the BSR on a round pole of 45 mm in diameter. The figure below summarizes of the MicroMAX's pole-mounting procedure. 28 Mounting the Base Station Radio (BSR) To pole mount the MicroMAX BSR:

1. Attach the mounting bracket to the MicroMAX:

a. Align the mounting bracket with the MicroMAX's mounting holes so that the mounting bracket's side with the built-in nut is aligned with the BSR's mounting holes furthest from the MicroMAX's bottom panel, as shown in the figure below. b. Slide an M10-flat washer and M10-spring lock washer onto an M10-hex head screw

(ensure spring lock washer is closest to the bolt's head). From the external side, insert the M10-hex head screw through the mounting bracket and MicroMAX's mounting holes. Fasten the M10-hex head screw (one is provided with a built-in nut while the other requires you to insert an M10-hex nut into the MicroMAX's mounting hole). 29 605-0000-742_MicroMAX_Hardware_Installation_Rev_G 2. Attach the clamping bracket to the mounting bracket:

a. Slide an M6-spring lock washer onto an M6-hex head screw. Align the mounting bracket's and clamping bracket's pivot holes, such that the clamping bracket is aligned to the inside of the mounting bracket. From the external side of the mounting bracket, insert the M6-hex head screw into the pivot holes and then fasten, but not tightly. (The clamping bracket provides a built-in nut.) b. Choose an elevation hole on the mounting bracket and then align it with the corresponding hole on the clamping bracket. Slide an M6-spring lock washer onto an M6-hex head screw, and then from the external side of the mounting bracket, insert the M6-hex head screw through the elevation hole on the mounting bracket and into the clamping bracket's corresponding hole. Fasten but not tightly the M6-hex head screw (the clamping bracket provides built-in nut). The elevation hole can later be changed according to desired antenna orientation in the elevation plane. 30 Mounting the Base Station Radio (BSR) 3. Attach the U-bolt to the pole:

a. Place one U-bolt around the pole, and then insert the U-bolt screw side through the two corresponding holes (horizontally parallel) on the clamping bracket. Slide an M8-

flat washer and M8-spring lock washer onto each U-bolt screw side (ensure that the flat washer is adjacent to the clamping bracket). Fasten each U-bolt side with the two M8-

hex nuts. b. Attach the second U-bolt as described above. 4. Perform final MicroMAX orientation:

a. Adjust the vertical position of the MicroMAX by choosing a final elevation hole as described in Step 2. Lock the MicroMAX at the desired position by inserting the locking bolt in the desired position and fastening it tightly. Fasten tightly the bolt in the pivot hole. The figure below illustrates the angles (in degrees) of each elevation hole. As 31 605-0000-742_MicroMAX_Hardware_Installation_Rev_G shown, the MicroMAX pole-mounting bracket allows elevation between -18.5 and 26.3. b. Adjust the horizontal position of the MicroMAX by rotating it about the pole, and then tightening the nuts of the U-bolts. Note: A thread-locking compound must be used to prevent the bolts from working loose. MicroMAX positioning is obtained in two planes by adjustment of the mounting bracket assembly as shown below. It is important to provide strain relief and drip loop for Cat-5 cables. Create a drip loop and strain relief using cable tie, to tie cable to pole, as displayed in the figure below:

32 Mounting the Base Station Radio (BSR) Wall-Mounting the BSR (Optional) Note: The standard BSR kit provides pole-mounting brackets. If you want to wall-mount the MicroMAX BSR contact your Airspan distributor for pricing and ordering of wall-mounting brackets. Note: A minimum of 3-meter separation is required between mounted MicroMAX's and existing customer radio equipment when transmitting on different sectors (see figure below). However, only a 1-meter separation is required between MicroMAX's when on the same sector and transmitting to the same base station radio without requiring shielding. The figure below illustrates the minimum separation between mounted MicroMAX's when transmitting on different sectors:

MicroMAX wall mounting consists of two main stages:

Attaching the mounting bracket to the MicroMAX's mounting holes Attaching the mounting bracket (already attached to the MicroMAX) to the wall (or pole) To wall mount the MicroMAX:

1. Position the unassembled mounting bracket on the mounting surface (e.g. wall), and then use a pencil to mark the position of the four mounting holes. Ensure that the distance between the hole centers are 120 mm (height) and 60 mm (width), as displayed in the figure below showing the MicroMAX's fixing dimensions. 33 605-0000-742_MicroMAX_Hardware_Installation_Rev_G 2. Drill holes for each hole that you marked in the step above. 3. Insert wall anchors (not supplied) into each of the drilled holes. 4. Align the mounting bracket's four holes with the wall anchors, and then insert a screw (not supplied) through the mounting bracket holes into each wall anchor, and then tighten. Note: Airspan does not provide screws for attaching the mounting bracket to the wall. The screw size depends on the structure of the building to which the bracket is to be attached. When selecting screw sizes, consideration must be given to the weight of the MicroMAX and load that may be induced in windy conditions. 34 Mounting the Base Station Radio (BSR) 5. Attach the MicroMAX to the mounting bracket by performing the following:

a. Slide an M10-spring lock washer and then an M10-plain washer onto each M10-hex head screw (ensure lock washer is nearest to head of screw bolt). b. Align the mounting bracket's holes with the MicroMAX's mounting holes as displayed below. (The mounting bracket side that provides a groove for inserting a nut must be aligned with the MicroMAX's mounting hole that is nearest to the MicroMAX's bottom panel.) c. From the external sides, insert the M10-hex head screws through the mounting bracket's holes and MicroMAX's mounting holes. Loosely fasten with the M10-hex nuts. 35 605-0000-742_MicroMAX_Hardware_Installation_Rev_G 6. Adjust the horizontal positioning of the MicroMAX (see "Web-Based Management" for MicroMAX antenna alignment using RSS measurements), and then tighten the two M10-hex head screws with the M10 hex nuts. Note: A third-party thread-locking compound must be applied to the M10-hex head screws to prevent the bolts from working loose. Note: For wall mounting, rotation is restricted in the horizontal plane only. Installing the SDA-4S The SDA-4S Type II (or SDA-4SDC Type II) is mounted vertically on a wall. Wall Mounting Wall mounting is made possible by the existence of two mounting hooks molded into the SDA-

4S's bottom panel, as displayed in the figure below. 36 Mounting the Base Station Radio (BSR) To wall mount the SDA-4S:

1. On the wall, mark the position of the two mounting hooks. The dimensions of the wall-

mounting hooks are displayed in the template below. 2. Drill holes for each hole that you marked in the step above. 3. Insert wall anchors (supplied) into each of the drilled holes. 4. Insert the 9-inch screws (supplied) into the wall anchors. Ensure at least 2 mm of the screw is exposed to allow insertion into the SDA-4S mounting holes. 5. Hold the SDA-4S with both hands, and align the entrance to the two mounting hooks with the screws. Slide the screws into the mounting hooks, by lowering the SDA-4S onto the screws. Note: For safety, both mounting hooks must be utilized when mounting the unit. Note: The SDA-4S is supplied with a 1-metre AC power lead assembly. Therefore, ensure the unit is mounted within reachable distance to the customer's mains power outlet. Note: The maximum cable run between SDA-4S and MicroMAX is 100 meters. Therefore, ensure the unit is mounted within reachable distance. 37 605-0000-742_MicroMAX_Hardware_Installation_Rev_G MOUNTING THE BSDU Mounting the BSDU The BSDU can be mounted in either of the two (2) following ways:

Horizontally on a desktop Horizontally in a rack (ETSI or 19) Desktop mounting The BSDU can simply be placed horizontally on a table. You can attach to the BSDU's bottom panel, four rubber feet (pads) (supplied) on each corner to provide cushioning and insulation from static electricity. Warning: To prevent a fire hazard caused by overheating, do not place the BSDU on a surface where airflow is restricted. Rack mounting The BSDU is designed for mounting in a standard 19-inch (48.3 cm) ETSI equipment rack or telco rack with 1-rack unit (1-U) of vertical rack space. Mounting bracket flanges are provided for mounting the BSDU into the cabinet, in its kit. Therefore, all that is required for mounting the BSDU is to attach the BSDU front-rail mounting brackets to the rack's mounting rails using the supplied four M5-mounting screws and plastic cup washers. To rack-mount the BSDU:

1. Determine the rack rail holes (left and right side) that will be used for attaching the chassis. 2. Insert four nuts into the rack's rail holes you designated in Step 1. These nuts are housed in Tinnerman clips, which allow you to fasten them into the rail holes. To insert the Tinnerman clips, hold the clips, squeeze them, and then insert them into the rail hole. 3. Carefully insert the BSDU into the rack, aligning the BSDU's mounting bracket holes with the rack rail holes. 4. Insert the M5-mounting screws, with plastic washers, into the BSDU mounting bracket holes, on each side, as shown in figure below. In this way, the chassis is supported until you tighten the chassis screws. 5. Tighten the M5-mounting screws to fasten the chassis to the cabinet. 38 Mounting the Base Station Radio (BSR) Note: When mounting multiple BSDUs in a cabinet, vertical spacing (above and below) is required for feeding cables to the rear. Note: The maximum cable run between BSDU and MicroMAX is 100 meters. Therefore, ensure the unit is mounted within reachable distance. 39 605-0000-742_MicroMAX_Hardware_Installation_Rev_G MOUNTING THE GPS Mounting the GPS Depending on individual customer requirements and environmental influences, there are several available options for mounting the GPS:

Pole Mounting: Using the 1" 14 threads, the GPS can be mounted onto a standard antenna mast or mounting adapter. (not supplied) Mounting Plate: Using three 10-32 UNF screws, the GPS can be mounted on a flat surface with three holes on a 1.75-inch diameter circle. (not supplied) Direct Mounting: The unit may be mounted directly to a suitable structure that has been provided with holes suited to the GPS mounting details. Pole Mounting Note: When mounting the GPS on a metal pole that is in physical contact with the ground, the GPS will not synchronize. To enable synchronization, you need to isolate the GPS from the pole using isolation material. 40 Mounting the Base Station Radio (BSR) MOUNTING AC/DC POWER CONVERTER Mounting the AC/DC Power Converter The AC/DC Power Converter is to be mounted horizontally in a rack (ETSI or 19) Rack mounting The AC/DC Power Converter is designed for mounting in a standard 19-inch (48.3 cm) ETSI equipment rack or telco rack with 1-rack unit (1-U) of vertical rack space. Mounting bracket flanges are provided for mounting the AC/DC Power Converter into the cabinet, in its kit. Therefore, all that is required for mounting the AC/DC Power Converter is to attach the AC/DC Power Converter front-rail mounting brackets to the rack's mounting rails using the four M5-

mounting screws and plastic cup washers. To rack-mount the AC/DC Power Converter:

1. Determine the rack rail holes (left and right side) that will be used for attaching the chassis. 2. Insert four nuts into the rack's rail holes you designated in Step 1. These nuts are housed in Tinnerman clips, which allow you to fasten them into the rail holes. To insert the Tinnerman clips, hold the clips, squeeze them, and then insert them into the rail hole. 3. Carefully insert the AC/DC Power Converter into the rack, aligning the AC/DC Power Converter's mounting bracket holes with the rack rail holes. 4. Insert the M5-mounting screws, with plastic washers, into the AC/DC Power Converter mounting bracket holes, on each side, as shown in figure below. In this way, the chassis is supported until you tighten the chassis screws. 5. Tighten the M5-mounting screws to fasten the chassis to the cabinet. Connecting Redundant PS Unit When required an additional PS unit is available (optional) for redundancy. This hot-swappable unit is designed for ease of installation. To install an additional PS unit 1. Check that the recessed on/off switch is in the off position 2. Determine the location to mount the redundant PS unit in the AC/DC Power Converter's chassis housing (usually to the left on the presently installed unit). 3. Carefully slide the unit on the rail tray until flush with front of AC/DC Power Converter's chassis housing. 4. Secure the unit by turning the Latch Lock screw, using a flat screw driver 5. Set the DIP switches (located on the back of the PS unit) to the on position for all 5 switches. 41 605-0000-742_MicroMAX_Hardware_Installation_Rev_G 42 CABLING THE BSR Network cabling at the Base Station depends on the devices implemented to provide the BSR with connectivity to the provider's backhaul and power source. These devices can be one of the following:

SDA: providing AC power and consisting of a single BSR BSDU: providing DC power and consisting of multiple BSRs Connecting the BSR to the SDA-4S he SDA-4S provides -48 VDC power to the BSR as well as the Fast Ethernet interface between the BSR and the provider's backhaul network. The outdoor Base Station Radio and Modem are powered over a CAT-5e Cable by the SDA-4S Type II IDU (or the SDA-4SDC) in the minimum configuration. For larger configurations N* SDA-4Ss and N* BSRs are required or connection to BSDU(s). The BSR interfaces with the subscriber's Ethernet network through the SDA-4S. To connect the BSR to the SDA-4S, you need to connect the BSR's 15-pin D-type port to the SDA-4S's 15-pin D-type port using a CAT-5e cable. The cable setup for MicroMAX-to-SDA-4S connectivity is as follows:

Cable: Straight-through CAT-5e Ethernet cable Connectors:

o MicroMAX: DB15-to-RJ45 outdoor adapter o SDA-4S: DB15-to-RJ45 indoor adapter (for connecting to DATA&PWR&SYNC D-type connector) o CAT 5e cable with 8-pin RJ-45 male connectors on either end Connector pinouts:

43 605-0000-742_MicroMAX_Hardware_Installation_Rev_G Note: The wire color-coding described in the table is Airspan's standard for wire color-

coding. However, if you implement your company's wire color-coding scheme, ensure that the wires are paired and twisted according to pin functions listed in the table above (e.g. Rx+

with Rx-). Note: The maximum CAT 5e cable length for ODU/IDU connectivity is 100 meters. To connect the BSR to the SDA-4S:

1. Connect the 15-pin D-type male connector, at one end of the CAT-5e cable, to the BSR's 15-pin D-type port labeled DATA&PWR&SYNC. 2. Connect the 15-pin D-type male connector, at the other end of the CAT-5e cable, to the SDA-4S's 15-pin D-type port. SDA-4S Type II Using the SDA-4S Type II The SDA-4S Type II (or the SDA-4SDC) provides one to four RJ-45 (100BaseT) ports for interfacing with the subscriber's LAN network. The ports of the SDA-4S model 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. PC) determines the speed at which packets are transmitted through the specific 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. Conversely, if the device to which the port is connected is running at 10 Mbps, the port connection will transmit packets at 10 Mbps In addition, the SDA-4S ports support MDI/MDI-X automatic crossover, allowing connection to straight-through or crossover CAT-5e cables. Therefore, these ports can be connected to either a hub (i.e. using crossover cables) or a PC (i.e. using straight-through cables). The cable setup for SDA-4S LAN connectivity is as follows:

Cable: Straight-through (e.g. when connecting to PC) or crossover (i.e. when connecting to a hub) CAT-5e Ethernet cable Connectors: 8-pin RJ-45 at both ends Connector pinouts:

Notes:

A CAT-5e cable connects to the 15-pin D-type port, therefore, only eight pins are used (i.e. pins 9 through 15 are not used). The wire color-coding described in the table (and shown in the figure below) is AS.MAX's standard for wire color-coding. However, if you implement your company's wire color-coding scheme, ensure wires are paired and twisted according to pin functions (e.g. Rx+ with Rx-). When the BSR is connected to an SDA, pins 7 and 8 are not used (i.e. no synchronization). To connect the BSR to the BSDU:

1. Connect the 15-pin D-type male connector, at one end of the CAT-5e cable, to the BSR's 15-pin D-type port labeled DATA&PWR&SYNC. 2. Connect the 15-pin D-type male connector, at the other end of the CAT-5e cable, to one of the eight BSDU's 15-pin D-type ports labeled BSR, located at the rear of the BSDU.

BSDU-to-PC local network management cabling 50 Cabling the BSR CONNECTING THE SDA-4S TO THE POWER SUPPLY Connecting the SDA-4S Type II The SDA-4S adapter is plugged into a standard electrical wall outlet (110/240 VAC) using an AC power cord. The appropriate AC power cord is supplied according to the country of use. The cable setup between the SDA-4S and power outlet includes the following:

Connector: AC IEC 60320 type (female) Plug: The appropriate plug type is supplied according to the country of use Cable: 3x1.z0 mm, 10A / 250 VAC (maximum length is 180 cm) To connect the SDA-4S to the AC power supply:

1. Connect the power plug female, at the end of the AC power chord, into the AC power socket located on the left panel of the SDA-4S. 2. Plug the power plug male, at the other end of the AC power chord, into the AC power outlet

(110-240 VAC). 3. Verify that the power is received by the SDA-4S by checking that the POWER LED light is on. 51 605-0000-742_MicroMAX_Hardware_Installation_Rev_G Verify that your SDA-4S is on and receiving power by checking that the LED labeled 4. POWER is lit (see SDA-4S LED description). Connecting the SDA-4SDC Type II The SDA-4SDC adapter is connected to the DC power supply using a cable appropriate to the specific field conditions. The setup between the SDA-4SDC and power connection includes the following:

Connector: Anderson Connector Housings for connecting the cable to the SDA-4SDC DC power socket. o 1327 - Red Housing x 1 o 1327G6 - Black Housing x 1 Note: Due to the variety of on-site conditions the cable is not supplied and should be acquired per specific connection needs. 52 Connecting SDA-4S to Ethernet Network The MicroMAX typically interfaces with the subscriber's network/computer using the SDA-4S or SDA-4SDC Type II which provides four (10/100BaseT) LAN ports for interfacing with the subscriber's LAN network. Cabling the BSR 53 605-0000-742_MicroMAX_Hardware_Installation_Rev_G CONNECTING POWER CABLE FOR SDA-4SDC Power Cable Connection In the SDA-4SDC installation Kit there are two polarized and genderless unassembled Anderson Powerpole power connectors: red for positive connection and black for the negative connection. Power connectors (Anderson Powerpole) The power connectors consist of housing (hood and a contact pins). The contact pin is displayed below:

Housing the Connectors The power connectors are supplied unassembled. Therefore, you need to crimp the power wires to the connector's contact pins, and then house them in the Powerpole hood. Crimping the power wires to the connectors:

1. Insert the wire into the contact pin's barrel, and then, with a standard crimping tool crimp the barrel tightly onto the wire (recommended 16 AWG cable wire). 2. Insert the contact into the hood with the contact's tongue pointing downwards and snap into place. Ensure that the housing spring mates with the underside of the contact's tongue. Connecting to the SDA-4SDC Once you have crimped the power cord to the Powerpole connectors, connect the power connectors to the SDA-4SDC power receptacles. To connect the power cord to the SDA-4SDC Note: The plastic housings are held together with dovetail joints. Always slide these joints together! They will be damaged if you try to snap them together or apart. They ONLY slide together in one direction. This should be obvious by looking at them carefully. 1. Assemble the red and black plastic housings together. Mate both connectors, by sliding them along the dovetail joints. When looking at the connector side (not the wire side), the red connector should be on the 54 left and the black on the right. The housing dovetails should be mated fully. 2. Connect the power connectors to the SDA-4SDC power receptacles so that the connectors'

color matches the receptacle's color, red to red (positive), and black to black (negative). 3. Connect the other end of the power cord to the third-party DC power source. Ensure that the positive and negative sides are correct. Cabling the BSR 55 605-0000-742_MicroMAX_Hardware_Installation_Rev_G CONNECTING LIGHTNING AND SURGE PROTECTOR The optional third-party lightning and surge protector (PolyPhaser) is implemented in the following deployment scenarios:

ODU-to-IDU cable length of 40 meters or more (mandatory to use surge protector) Deployment of MicroMAX in geographical areas that frequently experience severe lightning storms The lightning and surge protector protects the ODU-to-IDU CAT 5e cable's six used wires (two -48 VDC wires and four Ethernet Tx and Rx wires) from any electrical surges due to lighting strikes. The protector is installed outdoors on the CAT 5e cable that connects between the MicroMAX and the SDA-4S Type II. In other words, two CAT 5e cables are required for the following connections:

MicroMAX-to-protector connection Protector-to-IDU connection Warning: Do not install the lightning and surge protector during adverse weather conditions when the threat of lightning strike is possible. Note: The protector unit must be grounded to a low-impedance (low R and low L) ground system to operate properly. Note: For pricing and ordering of the PolyPhaser lightning and surge protector, contact your Airspan representative. To install the lightning protector:

1. Connect the protector in the direction according to the labels. The end labeled SURGE accepts the cable from the MicroMAX; the end labeled PROTECTED accepts the cable from the SDA-4S, or BSDU. 2. Feed the CAT 5e cable through the grommet (for each side). If the RJ-45 connector is already crimped to the other end, ensure that you have fed the cable through the gland nut beforehand. The gland nut secures the cable to the grommet. 3. Strip about 0.25" (6.35 mm) of the cable sheath and expose about 0.03" (0.8 mm) of the strands/wires. 4. Secure the wires to the protector's terminal block using the two spot ties. Each side of the data and DC assembly has + or markings to ensure lines entering (surge side) match lines exiting (protected side). Note: PolyPhaser should be installed close to the units but only externally. PolyPhaser Wiring Diagrams When working with SDA 56 When working with BSDU Cabling the BSR 57 605-0000-742_MicroMAX_Hardware_Installation_Rev_G 5. Mount and ground the protector outdoors with the provided 2 x 8-32 screws according to the fixing template illustrated below (showing distances between centers of the two mounting holes). The unit may be mounted/grounded on a nearby plate or bulkhead panel that is bonded to an earth-ground system. 6. Attach the protector's lid by using the four M4 x 20-mm screws. Ensure that the neoprene gasket on the lid is not loose or out of the groove. 7. Secure the CAT 5e cable to the grommet by fastening the gland nut. 58 Lightning and Surge Protection Connection Scenarios The figures below illustrate various lightning and surge protector connectivity scenarios.

The implementation of these antennas depends on the BSR model (with respect to radio antennas) and the need for synchronization of the system (with respect to GPS antennas). Connecting Third Party External Antennas The MicroMAX BSR model without a built-in antenna provides an N-type port for connecting a third-

party external antenna. The addition of an external antenna allows greater RF sector coverage than the standard MicroMAX BSR built-in antenna model. Warning: Before connecting the external antenna, ensure that the MicroMAX is not connected to the power source. Warning: Before powering on the MicroMAX, ensure that some type of equipment such as an antenna or an RF attenuator is connected to the N-type receptacle. This eliminates the risk of irreversibly damaging the MicroMAX device. Warning: It is the responsibility of the person installing the MicroMAX to ensure that only those antennas certified with the product are used. The use of any antenna other than those certified with the product is expressly forbidden. Warning: The external antenna must not be co-located or operating in conjunction with any other antenna or transmitter. Warning: The MicroMAX and external antenna should be installed ONLY by experienced installation professionals who are familiar with the local building and safety codes and are licensed by the appropriate government authorities. Note: The MicroMAX model that provides an N-type connector for attaching a third-party external antenna does not contain an internal, built-in antenna. The following lists the cable setup for attaching the external antenna:

Cable: RF coaxial Connector: N-type male To connect a third-party external antenna to the MicroMAX:

Connect the N-type male connector of the third-party antenna to the N-type receptacle located on the MicroMAX's panel (labeled ANTENNA), as displayed below. 62 Cabling the BSR Connecting GPS Antenna to BSDU Warning: To avoid electrical or fire hazard, ensure that the connection to the GPS is made prior to connecting the BSDU to the power supply. Warning: A primary lightning protection device must be provided by the operator/customer as part of an extra-building installation to ensure transient voltage levels of less than 600 V maximum. Warning: Changes or modifications to this equipment not expressly approved by Airspan Networks Inc. could result in violation of Part 15 of the FCC rules. Warning: This is a Class B product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures to correct the interference. Connecting the GPS The GPS antenna connects to the BSDU's 15-pin D-type port, labeled GPS, located on the BSDU's rear panel, as shown below. The connection to the GPS is made through a 12-pin RS-

422 serial interface port that provides both communication and power interfaces. BSDU rear panel showing GPS port 63 605-0000-742_MicroMAX_Hardware_Installation_Rev_G Warning: To avoid electrical or fire hazard, ensure that the connection to the GPS is made prior to connecting the BSDU to the power supply. The GPS-to-BSDU cable setup is as follows:

Cable: 12-pin conductor cable for RS-422 serial interface (multipair overall shielded -- 22 AWG) of 5, 15, or 30 meters in length depending on customer requirements Connectors:

o GPS side: RS-422 weathertight 12-pin plug (Deutsch MMP26C-2212S1) o BSDU side: 15-pin D-type male o Connector pinouts: The GPS connector receptacle contains 12 male contacts, as displayed below:

1. Connect the 12-pin female connector, at one end of the cable, to the 12-pin receptacle located on the underside of the GPS. 2. Connect the 15-pin D-type male connector, at the other end of the cable, to the 15-pin D-

type port labeled GPS located on the rear panel of the BSDU. 65 605-0000-742_MicroMAX_Hardware_Installation_Rev_G GPS-to-BSDU cable connection Notes:

When installing the cable, secure the cable to the mounting pole or bracket with a cable tie to hold the weight of the cable (i.e. cable strain relief). A loop should be left in the dressed cable for maintenance purposes and to prevent the cable weight being taken directly on the connector itself. Ensure that the connector is waterproof. GPS Alignment Many GPS reception problems can be reduced, to some degree, by careful antenna site selection. Place the GPS so that unobstructed line-of-sight reception is possible from horizon to horizon and at all bearings and elevation angles from the antenna. This is the ideal situation, which may not be possible under actual operating conditions. Try to place the GPS as far as possible from reflective objects, especially reflective objects that are above its radiation pattern horizon. Close-in reflections cause strong multipath signals. Care should also be taken to avoid coiling the GPS cable around the mounting base and pinching the cable in windows or doors. 66 TRADEMARKS AND COPYRIGHTS 1. Airspan Networks Inc 2007 2.

Telephone (44) 1 895 467450. 1.8 Lightning Protection WARNING: The following notes are general recommendations for the system. The wireless equipment should be installed by a qualified professional installer and must follow local and national codes for electrical grounding and safety. Failure to meet safety requirements and/or use of non-standard practices and procedures could result in personal injury and damage to equipment. A direct lightning strike may cause serious damage even if these guidelines are followed. All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced current from a near strike. Lightning protection and grounding practices in local and national electrical codes serve to minimize equipment damage, service outages, and serious injury. Reasons for lightning damage are summarized as:

- Poorly grounded tower/antenna sites that can conduct high lightning strike energy into equipment.

- Lack of properly installed lightning protection equipment that can cause equipment failures from lightning induced currents. A lighting protection system provides a means by which the energy may enter earth without passing through and damaging parts of a structure. A lightning protection system does not prevent lightning from striking; it provides a means for controlling it and preventing damage by providing a low resistance path for the discharge of energy to travel safely to ground. Improperly grounded connections are also a source of noise that can cause sensitive equipment to malfunction. A good tower grounding system disperses most of the surge energy from a tower strike away from the building and equipment. The remaining energy on the RF cable shield and center conductor can be directed safely to ground by using a lightning arrestor in series with the RF cable. To limit the equipment damage due to a lightning strike, the following practices are recommended for the wireless system:

- Provide direct grounding from the antenna mounting bracket, the radio and antenna and the lightning arrestors to the same ground point at the base of the tower or a ground bus on the building. Use the grounding screws on the antenna bracket and the radio and antenna for terminating the ground wires. 74 Warnings and Cautions

- Install one RF lightning protector between the radio and antenna in series with the RF cable.

- A lightning arrestor in series with the RF cable at the point of entry to the building.

- Install a lightning arrestor in series with the IF cable at the transceiver on the tower/mast.

- The AC wall outlet ground for the terminal must be connected to the same grounding system as the radio and antenna lightning protectors. 75 GLOSSARY A AAS: Adaptive antenna system (see Introduction for further details) AP: Access point API: Application programmers interface ATCA: Advanced telecommunications computing architecture BE: Best effort scheduling service for requesting uplink bandwidth B BER: Bit error rate BS: Base station BWA: Broadband wireless access CIR: Committed information rate used to specify the guaranteed data rate to the customer.
