Chapter 4 2.4-GHz Radio Upgrade for Autonomous Access Points

Upgrade Overview

Upgrade Overview

This section provides instructions for upgrading the autonomous access point 2.4-GHz radio.

Caution Your autonomous access point must be running Cisco IOS 12.2(13)JA or later before you upgrade to the IEEE 802.11g-compatible radio, otherwise your access point may not be able to complete the boot sequence until the radio is removed. For additional information, refer to the “Finding the Software Version” section.

The following operations summarize the upgrade procedure:

1.Remove all cables and power connections from the access point.

2.Follow standard electrostatic discharge (ESD) procedures.

3.Place the access point on an ESD-protected work surface.

4.Remove the access point’s back cover.

5.Remove the existing 2.4-GHz radio card.

6.Install the new 2.4-GHz radio card.

7.Replace the access point’s back cover.

8.Install the new compliance label.

Caution ESD can damage the Cisco Aironet radio and the internal components of the access point. It is recommended that the 2.4-GHz radio upgrade procedures be performed by an ESD-trained service technician at an ESD-protected workstation.

Note After you install the new radio, all configurable radio settings will be at default values. Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Pointsfor complete instructions on configuring the new radio.

Unpacking the Radio
