Weather Conditions When planning wireless bridge or mesh links, you must take into account any extreme weather conditions that are known to affect your location. Consider these factors:  Temperature: The wireless bridge or mesh link is tested for normal operation in temperatures from -30ºC to 55ºC. Operating in temperatures outside of this range may cause the unit to fail.  Wind Velocity: The wireless bridge or mesh link can operate in winds up to 165 miles per hour. 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.  Lightning: To protect against lightning induced surges, the W-AP175 requires lightning protection on the radio interface ports. CAUTION: A Dell Lightning Arrestor, AP-LAR-1, must be installed on each antenna port for protection against lightning induced surges. Failure to use an AP-LAR-1 can void the warranty of an Dell outdoor AP model and renders the AP susceptible to failure from lightning induced surges  Rain: The wireless bridge or mesh link is weatherproofed against rain. 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.  Snow and Ice: Falling snow, like rain, has no significant effect on the radio signal. However, a buildup 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, you must plan a cable route from the wireless bridge or mesh link outdoors to a suitable power and/or network source. Consider these points:  The ethernet cable length should never be longer than 90 m (295 ft).  Determine a building entry point for the cable (if applicable).  Determine if conduits, bracing, or other structures are required for safety or protection of the cable.  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 wireless bridge or mesh link, cables, and any supporting structures are properly grounded. Each W-AP175 access point includes a grounding screw for attaching a ground wire. CAUTION: Be sure that grounding is available and that it meets local and national electrical codes. Ground the access point first using the external ground stud on the unit before making any other connection. Installing Antennas 1. Before connecting the antennas, identify which of your antennas are 2.4 GHz and which are 5 GHz. On the W-AP175, the 2.4 GHz antennas must be installed the R1 radio interfaces and the 5.0 GHz must be installed on the R0 radio interfaces. 2. After identifying which antennas will go where, install them by placing the antenna connector over the corresponding connector and the AP and turning the connector clockwise until hand tight. Repeat this process for each antenna. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide 11
