Cisco Cisco 2000 Series Wireless LAN Controller

When installing an antenna, remember:

Do not use a metal ladder.

Do not work on a wet or windy day.

Do dress properly—shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt 
or jacket.

If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, 
cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch 
of any of these parts to a power line completes an electrical path through the antenna and the 
installer: you!

If any part of an antenna system should come in contact with a power line, do not touch it or try 
to remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur with the power lines, call for qualified emergency help immediately.

Refer to the appropriate Quick Start Guide or Hardware Installation Guide for instructions on installing 
your controllers and access points.

To meet regulatory restrictions, all external antenna configurations must be professionally installed.

Personnel installing the controllers and access points must understand wireless techniques and 
grounding methods. Access points with internal antennas can be installed by an experienced IT 
professional.

The controller must be installed by a network administrator or qualified IT professional, and the proper 
country code must be selected. Following installation, access to the controller should be password 
protected by the installer to maintain compliance with regulatory requirements and ensure proper unit 
functionality.

This section describes important information about the controllers and access points.

The Cisco 4400 Series Controllers are on the NIST FIPS 140-2 Pre-Validation List.

To support access points configured for use in Japan, you must upgrade the controller software to release 
3.2.116.21. Earlier releases do not support access points configured for use in Japan (regulatory domain 
-P).
