Plan the Location When you plan the OAP180 physical configuration, include the elements shown in this drawing: Figure 2: Sample Physical Layout Radio Position Planning Never construct a radio mast, pole, or tower near overhead power lines. In addition, local regulations may limit or prevent construction of a high radio mast or tower. If your OAP180 link requires a high radio mast or tower, consult a professional contractor for advice. Once the required antenna height has been determined, other factors affecting the precise position of the OAP180 must be considered. z Be sure there are no other radio antennas within 2 m (6 ft) of the OAP180. z Place the OAP180 away from power and telephone lines. z Avoid placing the OAP180 too close to any metallic, reflective surfaces, such as roofinstalled air-conditioning equipment, tinted windows, wire fences, or water pipes. Radio Interference Avoiding radio interference is an important part of wireless planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals using the 802.11a or 802.11bg channel frequencies. Always use a channel frequency that is furthest away from another signal. Weather Conditions Take into account any extreme weather conditions that are known to affect your location. Consider these factors: z Temperature — The OAP180 is tested for normal operation in temperatures from 40°C to 140°C. Operating in temperatures outside of this range may cause the unit to fail. OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. 7 of 24 z Wind Velocity — The OAP180 can operate in winds up to 44 m/s and survive higher wind speeds up to 66 m/s. You must consider the known maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force. z Lightning — The OAP180 includes its own built-in lightning surge protection. However, you should make sure that the unit, any supporting structure, and cables are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed. Antenna sockets should point upwards in a vertical manner z Rain — The OAP180 is weatherproofed against rain. Also, prolonged heavy rain has no significant effect on the radio signal. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection. If moisture enters a connector, it may cause a degradation in performance or even a complete failure of the link. z Snow and Ice — Falling snow, like rain, has no significant effect on the radio signal. However, a build up of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be cleared from the antennas to restore operation of the link. Ethernet Cabling When a suitable antenna location has been determined, plan a cable route from the OAP180 outdoors to the power injector module indoors. Consider these points: z The Ethernet cable length should never be longer than 100 m (328 ft). z Determine a building entry point for the cable. z Determine if conduits, bracing, or other structures are required for safety or protection of the cable. z For lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building. Grounding It is important that the OAP180, cables, and any supporting structures are properly grounded. The OAP180 unit includes a grounding screw for attaching a ground wire. Be sure that grounding is available and that it meets local and national electrical codes. Test Basic Link Operation Set up the OAP180 on the ground, either outdoors or indoors. Connect the unit as indicated in this document and perform the basic configuration tasks outlined below. When you are satisfied that the OAP180 is operating correctly, proceed to mounting the unit in the intended location. 8 of 24 OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. Mount the Unit The OAP180 can be mounted on the following two surfaces (brackets are included): z 1.5 to 2 inch diameter pole z Wall Mounting OAP180 with the Pole-Mounting Bracket Perform the following steps to mount the unit to a 1.5 to 2 inch diameter steel pole or tube using the mounting bracket: 1.

Figure 6: Connecting the Two Brackets 12 of 24 OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. Connect External Antennas and Ground Wire to OAP180 When deploying an OAP180, first mount external antennas and then connect them to the OAP180. Follow these steps: 1. Mount the external antenna on the same supporting structure as you did the OAP180, within 3 m (10 ft) of it, using the bracket supplied in the antenna package. 2. Connect the antenna to the OAP180’s N-type connector using the RF coaxial cable provided in the antenna package. Figure 7: Connect the Antenna Cables 3. Apply weatherproofing tape to the antenna connectors to help prevent water entering the connectors. OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. 13 of 24 Connect Cables to the Unit Use only the provided Ethernet cable in step 1. Do not shorten this cable as the path loss is needed. During periods of lightning activity, do not connect or disconnect cables or otherwise work with the OAP180. Perform the following steps to attach the Ethernet cable and ground wire: 1. Using the included cable, attach the Ethernet cable to the Ethernet port on the OAP180. See Figure 8. Figure 8: Connecting the Ethernet Cable and Ground Wire 2. For extra protection against rain or moisture, apply weatherproofing tape (not included) around the Ethernet connector. 3. Ground the unit with an appropriate grounding wire (not included) by attaching it to the grounding screw on the unit. See Figure 8. Be sure that grounding is available and that it meets local and national electrical codes. For additional lightning protection, use lightning rods, lightning arrestors, or surge suppressors. Caution! 14 of 24 OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. Connect the Power Injector Caution! Do not locate the power injector outdoors. The unit is for indoor use only. Note: The wireless Ethernet port does not support Power over Ethernet (PoE) based on the IEEE 802.3af standard. Do not try to power the unit by connecting it directly to a network switch that provides IEEE 802.3af PoE. Always connect the unit to the included power injector module. Perform the following steps to connect the power injector: 1. Connect the other end of the provided Ethernet cable (already connected to the OAP180) to the RJ-45 port labeled Output on the power injector. See Figure 9. Figure 9: Connecting the Power Injector 2. Connect a straight-through unshielded twisted-pair (UTP) cable (not included) from a local LAN switch to the RJ-45 port labeled Input on the power injector. See Figure 9. Use Category 5e or better UTP cable for 10/100BASE-TX connections. Note: The RJ-45 port on the power injector is an MDI port. If connecting directly to a computer for testing the link, use a crossover cable. 3. Insert the power cable plug directly into the standard AC receptacle on the power injector. See Figure 9. 4. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source. For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. Note: 5. Check the LED on top of the power injector to be sure that power is being supplied to the OAP180 through the Ethernet connection. OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc. 15 of 24 Align Antenna After the OAP180 unit is mounted, connected, and the radios are operating, the antennas must be accurately aligned to ensure optimum performance of the OAP180 links. In this point-to-multipoint configuration all OAP180 nodes must be aligned with the root OAP180 antenna. Check the OAP180 for Activity Check the OAP180 LEDs for activity. Four of the eight LEDs on the bottom of the OAP180 indicate activity; four LEDs are not used at this time. Check the four active LEDs to determine if the AP is working.
