AR/GE/FE/U 80/80X Installation Manual 2 Site Planning 2.1 General Before the start of any installation, a survey of the planned deployment site should be conducted first. The surveying personnel should be fully familiar with the details and requirements needed to successfully install the 80GHz radio system. 2.2 Equipment Checklist We suggest the site survey team may need the following equipment: · Binoculars (not always required) · WAAScapable GPS location device · Tape measure to determine distances for cable runs to ingress points · Digital camera (not always required) · Site survey report form to document and help assess site · Signaling mirror (provided but not always required) · 7090GHz Link Registration Datasheet. Contact BridgeWave Tech Support to learn where one can obtain the latest version of this form. You may Email support@bridgewave.com for this request or request it online via eService Center http://bridgewave.com/support. 2.3 Line of Sight (LOS) The 80GHz Wireless Gigabit Ethernet link requires LOS for proper operation. Binoculars and spotting mirrors may be used to assist in the confirmation of LOS. Path planning should include an investigation into future building plans that could block the LOS path, and other longterm incremental obstructions such as tree growth. Intermittent obstructions such as aircraft at a nearby airport should also be considered. 3 58000519 rev. D ...
4.3 10000 1.8 6.21 5.9 2.4 Link Distance Measurement of the link distance is important in estimating the link availability and calculating expected Receive Signal Level (RSL). This measurement can be performed using the Latitude and Longitude coordinate readings from a Global Positioning System (GPS) device, which is placed near the proposed locations of the antennas. Additionally GPS reading will be required in order to comply with the FCC registration process. The Minimum 80GHz Link distances are as follows: · AR/GE/FE80: 328 feet (100 meters) · AR/GE/FE80X: 1312 feet (400 meters) To estimate maximum distances and availabilities for a given product and region, BridgeWave’s Path Availability calculator can be used. To obtain the latest version of BridgeWave’s Path Availability calculator, contact BridgeWave’s Customer Service or search eService Center Knowledgebase. 2.5 Antenna Location The optimum location for the antennas must be determined. The ideal location should provide for ease of erecting and mounting the antenna, as well as providing unimpeded LOS to the remote location. The following factors should be taken into account: · Type of mounting—fixed or roofsafe pole mounting. · Location of fiber and DC power wiring ingress/egress of the building. · Length of cable runs. · Confirmed Earth Grounding connection points. · Obstructions, including allowances for tree growth. · Accessibility of the radio mounting location. · Accessibility of the site during and after working hours.
2.6 Cabling The installation site should be inspected to determine the run paths for the fiber cable and power cable from the radio equipment to the termination point. Locations for roof penetration should be identified. The routing and securing of all cables should conform to all applicable codes and requirements. Depending on the likelihood of damage due to foot traffic or equipment movement, cabling conduit may be required. The maximum cable run length as specified for the equipment being installed must not be exceeded, refer to Table 2.61 and 2.62 for cable types and limitations. The radio requires LC type connectors on duplex multimode fibers to properly connect between the radio and the users network equipment. Singlemode fiber connections are not supported for use with the standard product. The network equipment end of the fibers should be terminated with connectors that match the user’s network equipment fiber interface. Table 2.61: Maximum Fiber Length Fiber Cable Length Cable Type Up to 270 meters 62.5/125 μm Up to 500 meters 50/125 μm The 80GHz radio includes a 100240 VAC power adaptor, suitable for indoor operation only, that converts the AC voltage from a standard electrical outlet in the wall to DC voltage. For outdoor rated power supply options, contact BridgeWave customer service. The radio requires a minimum of 15.0 VDC at the connector on the radio unit (24.0 VDC maximum) to function properly. When planning the cable run from the indoor AC power adaptor to the radio unit, it is required to use the cable gauge (AWG) indicated below to ensure adequate voltage at the radio. The indoor and outdoor portions of the DC power cabling must conform to all respective indoor and outdoor national and local electrical and building codes; note that requirements may differ for the indoor and outdoor portions of the cabling and that a grounded surge protector is normally required at the point where the cable enters the building. The DC power cabling must consist of two 12 or 14 gauge stranded conductors based on the required cable run length. Table 2.62: Minimum DC Cable Size DC Cable Length Conductor Size Up to 125 meters 14 AWG (2.5mm²) Up to 200 meters 12 AWG (4mm²) Figure 2.61 shows a standard 14gauge wire that has been fitted with the power connectors (provided) for the radio’s internal power supply necessary to mate with the (not provided) DC power 5 ...
AR/GE/FE/U 80/80X Installation Manual cables. A standard crimping/splicing tool (not provided) is required to terminate the power connectors onto a 1412gauge cable required for use with the 80GHz. On the radio end no connectors are required; simply screw terminals to appropriate polarity. The DC power cable should be fed into the connector on the casing first and then the green connector attached to the radio after making a strain relief coil around the electronic housing. Figure 2.61: (Left) 14gauge DC power cable terminated to radio end. (Right) DC 14gauge cable from the power supply end. 2.7 Grounding & Lightning Proper grounding of the outdoor equipment reduces electromagnetic interference, provides lightning protection, and protects against electrical discharge. Using improper techniques in lightning prone geographic areas may pose a danger to local personnel. The source and connection points for the buildingtoearth ground in the vicinity of the antenna location should be determined. In addition to grounding the equipment, BridgeWave strongly recommends, and local building codes may require, the DC electrical cable to be protected from electrical surges by a surge suppressor. The surge suppressor must be installed at the point where the DC electrical cables exit/enter the building. 6 58000519 rev. D ...

AR/GE/FE/U 80/80X Installation Manual 3.7 Cable Installation 3.7.1 Fiber Cabling 1. Install a duplex multimode fiber from the radio to the network termination equipment (switch or router with 1000BaseX port). The cable should be looped around the inside of the enclosure to provide strainrelief. Do not connect the fibers to the radio’s fiber ports at this time. The connectors on the radio end of the fiber require two LC connectors; the connectors on the switch/router end should mate to the network equipment. 2. Connect fibers at the network equipment. It is important not to connect the fibers to the radio until after aligning the radio as the radio performs an automatic calibration once the fiber is inserted into the radio and this calibration will not operate properly if the radio is not properly aligned. If this inadvertently occurs while the radio is powered on, unplug the fibers and power cycle the radio. 3.7.2 Power Cabling 1. Select indoor location, with easy cable routing to the radio, for the AC power adaptor. Normally it is convenient, but not required, to place the adaptor near the network termination equipment. 2. Ensure the DC wire used is 14gauge type and no longer than 125 meters; or 12gauge and no longer then 200 meters. 3. Connect the provided DC Connectors onto the 14guage wire using a splicing/crimping tool. For the use of 12gauge wire it may be necessary to trim a few strands from the ends of thicker stranded cables to more easily fit the crimp connectors. 4. Install the DC power cable and attach to the AC adaptor using the supplied crimp connectors. Do not connect the power jack to the radio at this time. The fiber and power cables are inserted through the straight through fitting before the 3/4" flexible conduit is connected to the fitting. Ensure that the cables do not get pinched when the conduit is pushed onto the fitting. Both cables should be looped around the inside of the enclosure to minimize tension on the cables when ...

The NMS ’Status Page’ reading will still read 24V. Figure 3.7.21: 80GHz power and data cables with service loop for strain relief and proper fiber bend radius. 3.7.3 Ground Cabling The preferred method for grounding the radio unit is to ground the mast to a ground source, since this provides the largest grounding surface contact possible. If this is not possible, then use the following procedure: 1. Attach the lug of the ground cable (not provided) with the radio to one of the two #8 holes at the bottom of the radio using a #832 x ½” long bolt, #8 lock washer and #8 flat washers (not provided). 2. Connect other end of the ground cable to a nearby ground location. 3.7.4 10/100BaseT Surge Suppressor If the 10/100BaseT port is permanently connected to other network equipment (not normally required), it should be connected using Cat5e UTP cables rated for the outdoor and/or indoor environments where the cables will be run. It is essential that the cabling be connected to the radio unit through an Ethernetrated surge suppressor inside of the plastic back cover of the unit, and a surge suppressor should also be used at the point where the cable enters a building or is connected to other outdoor equipment that does not already contain surge suppression hardware. 17 58000519 rev.

AR/GE/FE/U 80/80X Installation Manual 3.8 Ice Shield Canopy Installation The Ice Shield assembly is an optional item and can be ordered in kit form through a BridgeWave sales or distribution partner. 3.8.1 Introduction In northern climates, the buildup of ice or snow on antennas can be a problem for millimeter wave radio installations. These problems are twofold: the electrical effect of snow and ice built up on the antenna’s radome; and the mechanical impact of the additional weight of the snow or ice on the antenna and supporting structure. The formation of ice or snow on the antennas radome can cause attenuation of the signal to the point where the link may become severely degraded or unusable. Uneven ice buildup can cause scattering of the signal, which in turn results in standing waves. At 80GHz, ice buildup less than 1mm thick (onequarter wavelength at 80GHz) may result in degraded performance of the link. Such thin layers are not likely to exist for extended periods, as ice tends to melt. In cold climates when the radome is below freezing temperature, ice does not stick to it, thus there is no issue. However in mixed rainsnowice storms, ice can stick to the radome, causing the link to operate at less than its optimal design. Once the ice has hardened and freezes, the added weight of the ice on the antenna increases the wind load on the tower or mast, which may cause premature failure of the mounting structure. As ice breaks apart due to melting, or via its own weight, these large and heavy sheets falling down a tower or mast can cause damage to antennas or other objects mounted below. 19 58000519 rev.

AR/GE/FE/U 80/80X Installation Manual 3.9 Antenna Alignment 3.9.1 Before Turning On the System 1. Finish the installation as described in Chapter 3.5 and 3.6 2. Ensure fiber cables are still disconnected! 3.9.2 Connect DC power to the radio. 3. Verify that the Power LED is lit. If the Power LED is not lit, carefully use the voltmeter to verify the correct voltage and polarity at the radio connector. Turn off the Power Supply before making any corrections. 4. Repeat steps 1 through 3 on the farend of the link. 3.9.3 Prepare to rough align the radio. 5. Connect RSL test lead cable to radio and place voltmeter with readings in view. 6. Loosen the pole mount brackets enough to allow you to swing the unit horizontally. 7. Reference Chapter 3.5 for illustration of antenna mount bolts and their purpose. 3.9.4 Rough align the radio antennas 8. Set the radio terminal to the predefined azimuth if available. If not, you may utilize binoculars or signal mirror to locate the far end radio location. 9. If you can see the farend radio terminal estimate the alignment visually and tighten the pole mount brackets with fine adjustment bolt set to the middle of adjustment range. 10. Ensure the horizontal adjustment bolts are snug; only tighten bolts one quarter of a turn. 11. Slightly rotate each antenna up/down for best vertical alignment and left/right for best ...

AR/GE/FE/U 80/80X Installation Manual 13. Repeat these steps on far end radio. 3.9.5 Fine Adjustment 14. Ensure to loosen the “fine adjustment” bolt (the small eye bolt). 15. Pan antenna slowly from left to right and capture the highest RSL voltage peak. 16. See Figure 3.9.51 below to help guide you in obtaining the highest RSL voltage reading. 17. Tighten down the azimuth adjustment bolts. 18. Loosen the two bolts holding the antenna to the antenna mount. 19. The vertical fine adjustment bolt is not designed to be tightened; use the “hex nut” to fine (and course) adjust the elevation (vertical position) to highest RSL value. 20. While monitoring the voltmeter, begin to align the vertical position of the antenna to obtain the highest RSL voltage level. 21. Once completed, this fine adjustment must be repeated at the remote end of the system, if you have not obtained the “target” RSL voltage for the given path distance (see RSL Vs. distance chart in Appendix B). 22. If you have not obtained the “target” RSL voltage for the given path distance (or you want to further improve it), you will need to realign the antenna, go back to the original site you started with and restart steps 1421 and realign again. See Figure 3.9.51 below of a conceptual illustration of the antenna beam to keep in mind while you perform a re alignment. 23. Once again, the very narrow beam width of these antennas (0.4º and 0.9º) makes it necessary to completely tighten the bolts of the azimuth adjustment while adjusting the elevation and vice versa. Verify that the RSL voltage falls within the expected range based on the graph in Appendix B. 23 58000519 rev. D ...

AR/GE/FE/U 80/80X Installation Manual 3.9.6 Locking Down Radio Antenna 24. After the target RSL level has been achieved, ensure all bolts are tightened evenly, securely and ensure the RSL voltage remains unchanged after tightening is completed. 25. The very narrow beam width of this antenna (0.4º and 0.9º) makes it necessary to completely tighten the bolts of the azimuth adjustment while adjusting the elevation and vice versa. 26. Always evenly tighten bolts in small fractions at a time to ensure minimum change to your completed alignment. 3.9.7 Connecting the Fiber Connect the fiber cable to one of the radios at a time. The fibers should already be connected to active network equipment. The fiber integrity indication on the network equipment could show up or down independent of the RF link status. 3.9.8 Auto Calibration 27. Once the fiber is connected to the radio, the radio will begin an internal link calibration. 28. During this time the Link Up LED will blink for up to 120 seconds. 29. Wait until the Link Up LED is lit solid 30. Verify the Link Quality voltage is 3.03.3V (i.e., error free). Repeat steps (3032) for the far end radio. For more details on Auto Calibration see section 39 below 3.9.9 Remove the Test Cable 31. Remove the test cable from the radio, replace the rear plastic cover and hand tighten the back cover nut to the point where the back cover stops (i.e. when it hits the metal ring on the back metal plate). The installation is now complete. The most important alignment ‘tool’ for these models is care and patience! It is recommended that these models be aligned with personnel present at both ends of the link, and the installers should allow 90 minutes to optimally align these units. 80 and 80X antennas exhibit narrow beam widths of 0.9º and 0.4º. Link distances are great and alignment becomes more critical.
AR/GE/FE/U 80/80X Installation Manual 3.10 Auto Calibration The Auto Calibration feature scans the receive signal across the entire (broad) band and flattens the levels, much like the equalizer on your home or car stereo. The radio system is said to be in “Alignment Mode” when it is first powered up with no fiber connected. The Auto Calibration mode is triggered ON as soon as the fiber cable is connected. The fiber interface of the radio terminal needs to detect an optical signal of the appropriate wavelength. This requires the fiber optic cables be connected to a 1000BaseX port on an Ethernet device (switch, router, media converter, etc.) or this can be accomplished with a fiber optic loopback cable by connecting the fiber output of the radio into the fiber input of the radio. If used, the loopback cable should only be connected long enough for autocalibration to start and should be removed immediately. The radio terminal indicates the Auto Calibration by flashing the Link LED on/off this cycle lasts for up to 120 seconds. Autocalibration is a required step per installation once antenna alignment is completed. 3.10.1 AdaptRate™ Fiber Calibration Procedure (AR80 and AR80X only) In order for an Adaptive Rate link to operate correctly, it is especially critical to ensure the following process is followed exactly. If you feel this process may not have been followed or you wish to re attempt the process, be sure to first power down both radios, remove any fiber connection before turning the system on. This will get you back to original factory radio calibration settings and place the radio link in “alignment mode”. START: 1. First, with a local PC, view each radio's Setup page and make sure the operating mode is set to AR and that the Installation Auto Calibration is 'enabled' at both ends. The default value is ‘enabled’. VERIFICATION: Double check this setting on both radios. 2. On initial Power up, do not connect any fiber cables VERIFICATION: It is best to physically disconnect any fiber cables from the radio unit ports, rather than just relying on the far ends of the cables being disconnected. 3. Upon completing the antenna alignment procedure, make sure both ends have a minimum of 2VDC in Quality voltage, if not, further alignment may be required. Small fluctuations are okay. 26 58000519 rev. D ...

AR/GE/FE/U 80/80X Installation Manual If you do not obtain a Quality voltage of 2VDC, do not proceed to calibrate the system. Ensure you are aligned and achieve your target RSL level. This can be confirmed for your path distance by looking up the RSL voltage to distance curve in Appendix B. 4. At this point you need to connect the fiber cable (or a fiber loopback if no network gear is terminated to the far end of the fiber). If using a fiber loopback, remove immediately when the Link LED starts blinking. Calibrate one side at a time and while monitoring the Quality voltage with DVM. Verify you are getting a 'quadruple hump'. i.e. voltage will rise, drop, rise, drop, and rise again, as illustrated below. It should end with a 3.0VDC to 3.3VDC reading on your DVM. Also verify the radio ‘Link LED’ is also ‘flashing’ on/off during this process. See Figure 3.10.11 for an illustration of the Quality Voltage as it fluctuates during the calibration process. Quality Voltage during Calibration Process (90120 sec.) 10 sec. 2.0 3.3VDC Fiber connected, Radio Link Radio Link LED LED starts flashing stops flashing Figure 3.10.11: Quality Voltage reading during Auto Calibration process If you cannot obtain a good quality voltage and you have obtained the target RSL, contact Technical Support at (408) 5676906 or email support@bridgewave.com for further assistance. You must wait for the Auto Calibration process to complete on one radio terminal before auto calibrating the remote radio and ensure both radios pass the calibration process. Failure to wait for the calibration to complete may result in a failure to create an RF connection between radio terminals. 27 58000519 rev. D ...

AR/GE/FE/U 80/80X Installation Manual At this point, open the Status page from the unit’s NMS interface and ensure the Radio TX and RX is operating at 1000 Mbps for both radios. Click the refresh button a few times to ensure it is a good reading. If all indicators are good, then go to the next steps. If not, then go back to step 1 or contact BridgeWave Technical Support for assistance. 5. Go to Statistics page and reset the stats for each radio end. 6. Perform a ping test. Open two command line windows and ping the local and remote management agent. Factory default IPs are; 192.168.0.1 for lowband and 192.168.0.2 for highband and perform a ping to both ends and wait a few minutes, ensure you are getting responses from the local and remote management agents. 7. Review statistics page results and ensure packets are being transmitted, received, and there are no excessive error conditions. 8. If all is performing well, you must now 'disable' the InstallationAuto Calibration option on the Setup page of each radio. 3.10.2 Installation AutoCalibration Feature (AdaptRate™ models only): This feature should be disabled only after the radio system has been completely installed and calibrated as described above. In the NMS ‘Setup’ screen, select Installation AutoCalibration to ‘Disable’ and press the ‘Submit new Values button at the bottom of the screen Figure 3.10.21: Installation AutoCalibration Setting (AUTO CALIBRATION FINISHED) 28 58000519 rev.

AR/GE/FE/U 80/80X Installation Manual Failure to ‘Disable’ the Installation AutoCalibration option can trigger an inadvertent recalibration of the system, under certain power failure conditions. 3.10.3 Forced ReCalibration Option 1: Use the AutoCal function in the NMS ‘Maintenance screen. This function will store the calibration values in nonvolatile memory. Option 2: Enable “installation auto calibration” in the NMS and ‘Apply Settings'. Disconnect the DC power and fiber optic cables from the radio. Power up the radio while the fiber is still disconnected. The Auto Calibration will start as soon as the fiber optic cable is reconnected to the radio terminal. When a radio is power cycled with the fiber connected to network equipment, the radio will use the calibration values stored in nonvolatile memory from the last successful autocalibration process even if the enable AutoCal setting being set to ‘Enable’. The radio link will come up immediately. When a radio has “Installation Auto Calibration” disabled, the radio will use the calibration values stored in nonvolatile memory from the last successful autocalibration process, regardless of the fiber interface connected to network equipment or not. Should moving the link to a new location or realignment of the link become necessary, the link must be recalibrated per the auto calibration procedure described in Section 3.10. 29 58000519 rev.

AR/GE/FE/U 80/80X Installation Manual 3.11 QUAL & RSL Test Cable The alignment procedure is optimized through the use of the provided test cable. This test cable is designed for use with a digital voltmeter (not provided) to read the Link Quality and Receive Signal Level (RSL) voltage generated by the radio’s receiver. See Figure 3.111. Figure 3.111: Supplied test cable for measuring Link Quality and Receive Signal Level voltages 1. To read the RSL value of the radio, insert GND (ground) and RSL banana plugs into the voltmeter. Note the RSL voltage. The voltage may be fluctuating; in this case, note the maximum value seen. 2. To read the Link Quality value of the radio, insert GND (ground) and QUAL banana plugs into the voltmeter. Note the Link Quality voltage. After the radios have performed an auto calibration the quality voltage should read 3.03.3VDC if the link is aligned on the main antenna beam and there are no obstructions (i.e., trees, buildings, etc…) in the path, the link distance is within the operating parameters of the radio (see Section 2.4 above), and it is not raining heavily. 30 58000519 rev.
