Cisco Cisco 4402 Wireless LAN Controller

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 
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.

You must install software release 4.0.179.8 on the controller before connecting 1100 and 1300 series 
access points to the controller.

The 1500 series access points may take up to 10 minutes to fully associate to the controller on initial 
startup.

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