Installing a Lightning Arrestor
Using a Mounting Bracket for External Directional Antennas
You can use the AIR-ACCAMK-2= bracket for mounting a directional antenna directly on the access
point. See Figure 2-25.

Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct
contact with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning
Arrestor limits the amplitude and duration of disturbing interference voltages and improves the over
voltage resistance of in-line equipment, systems, and components. A lightning arrestor installed
according to these mounting instructions balances the voltage potential, thus preventing inductive
interference to parallel signal lines within the protected system.
Installation Considerations
Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed
through on the wall of the protected space.
1 Slots to be used for managing the antenna cables with
cable ties.
3 Note the direction of the arrow. Ensure that the bracket
and AP are mounted with the arrow pointing upwards.
