OAP180 Hardware Installation Instructions 7 of 24© 2007 Meru Networks, Inc.Plan the LocationWhen you plan the OAP180 physical configuration, include the elements shown in this drawing:Figure 2: Sample Physical Layout Radio Position PlanningNever 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.zBe sure there are no other radio antennas within 2 m (6 ft) of the OAP180.zPlace the OAP180 away from power and telephone lines.zAvoid placing the OAP180 too close to any metallic, reflective surfaces, such as roof-installed air-conditioning equipment, tinted windows, wire fences, or water pipes.Radio InterferenceAvoiding 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 ConditionsTake into account any extreme weather conditions that are known to affect your loca-tion. Consider these factors: zTemperature — 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.
8 of 24 OAP180 Hardware Installation Instructions © 2007 Meru Networks, Inc.zWind 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.zLightning — 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 mannerzRain — 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.zSnow 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 CablingWhen a suitable antenna location has been determined, plan a cable route from the OAP180 outdoors to the power injector module indoors. Consider these points:zThe Ethernet cable length should never be longer than 100 m (328 ft).zDetermine a building entry point for the cable.zDetermine if conduits, bracing, or other structures are required for safety or protection of the cable.zFor lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building.GroundingIt 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 OperationSet up the OAP180 on the ground, either outdoors or indoors. Connect the unit as indi-cated 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.
