Mounting The Access Point - Cisco AIR-LAP1310G Mounting Instructions

Mounting the Access Point

Lightning Arrestor
In outdoor antenna installations, your antenna and access point can be damaged by surges that develop
on the antenna and cable from close lightning strikes. You can use a lightning arrestor (such as
AIR-ACC-3354) to help protect your access point system from static electricity and lightning-induced
surges; however, an arrestor will not prevent damage from a direct lightning hit.
A lightning arrestor is a 50-ohm transmission line with a gas discharge tube positioned between the
center conductor and ground. This gas discharge tube changes from an open circuit to a short circuit
almost instantly (100 nanoseconds) in the presence of voltage and energy surges, providing a path to
ground for the energy surge.
A lightning arrestor should be installed between your outdoor antenna and the access point. You should
connect a 6 AWG copper wire from the arrestor to a good earth ground.

Personnel installing the access point must understand wireless installation techniques and grounding
methods.
Note To meet regulatory restrictions, the external antenna access point unit and the external antenna must be
professionally installed. The network administration or other IT professional responsible for installing and
configuring the unit is a suitable professional installer. Following installation, access to the unit should be
password protected by the network administrator to maintain regulatory compliance.
These procedures focus on general mounting and cable-routing topics. For information about assembling
the mounting hardware, see the
