Cisco Systems 102053 Manual De Usuario

This section provides instructions for upgrading the access point 5-GHz radio module (RM20A, 
RM21A, or RM22A). The following operations summarize the upgrade procedure: 

Remove all cables and power connections from the access point.

Place your access point on a flat surface.

For an access point without the 5-GHz radio feature, remove the 5-GHz radio access cover.

For an access point with the 5-GHz radio feature, remove the existing 5-GHz radio module.

Install the new 5-GHz radio module.

Your access point must be running Cisco IOS Release 12.3(2)JA or later before you upgrade to the 
RM21A or RM22A radio module; otherwise your access point may not be able to complete the boot 
sequence until the radio is removed. For additional information, refer to the 

 section.

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

Each 5-GHz radio module is shipped with the following items:

Quick start guide

A product registration card

A T-10 tamper-resistant Torx L-wrench

A 5-GHz radio compliance label

If anything is missing or damaged, contact your Cisco representative for support.

On access points without an installed 5-GHz radio module, you must remove the access cover that covers 
the 5-GHz radio slot. To remove the 5-GHz radio access cover, follow these steps:

Remove all cables and power connections from the access point.

Place the access point on a flat surface so that the unit is upright with the front end facing you.
