After you have followed this procedure, you can use the procedure in the Use the Aironet Conversion Tool to
Upgrade from VxWorks to Cisco IOS Software section of this document in order to convert the VxWorks
firmware to Cisco IOS Software.

The Conversion Tool is a special utility that administrators use to do these actions:

Create a Cisco IOS configuration from the configuration of an existing VxWorks 350 or 1200 Series
AP.

• 

Store a Cisco IOS configuration file on your PC for later use.

• 

Combine a Cisco IOS configuration file with a 350 Series helper image in order to upgrade VxWorks
350 Series APs to Cisco IOS operation.

• 

Combine a Cisco IOS configuration file with a 1200 Series helper image in order to upgrade
VxWorks 1200 Series APs to Cisco IOS operation.

• 

Note: This document does not cover the use of the Aironet Conversion Tool. Refer to the Release Notes for
Cisco Aironet Conversion Tool 2.1 for Cisco IOS Software and the Cisco Aironet Conversion Tool for Cisco
IOS Software, 2.1 Administrator Guide for Windows.

If you want only to upgrade a VxWorks 350 or 1200 Series AP to Cisco IOS Software and you do not want to
preserve the previous configuration, use the 350 or 1200 Series helper image file in order to upgrade the AP.
You can find this procedure in Upgrading an Access Point to Cisco IOS Operation Without the Conversion
Tool.

Note: Ensure that firewalls are not enabled on the TFTP server PC which is used for the upgrade. The firewall
could block the broadcast TFTP request and therefore cause the upgrade to fail.

Note: Although this document focuses on the Aironet 1200, you can use the Conversion Tool to upgrade both
the 1200 and 350 Series APs. Therefore, there are references to the Aironet 350 in this document. You can
find information about how to upgrade the 350 Series in the Release Notes for Cisco Aironet Conversion Tool
2.1 for Cisco IOS Software and the Cisco Aironet Conversion Tool for Cisco IOS Software, 2.1 Administrator
Guide for Windows.

If you do not have sufficient system DRAM resources, the upgrade process fails. Unless you make a console
connection during the upgrade process, such a failure may not be readily visible. The only clear failure
symptom is an unfamiliar blink pattern in the LEDs on the top of the unit.

If you have a console connection during such a failure, you can see warnings that are similar to these:

Retrieving file "10.0.0.11:UpgradeImage10.0.0.108Jun20.img" via TFTP.

*** Suppressing console event log display due to low memory.

*** Restarting System in 5 seconds...

*** Recovered from low−memory condition. Restoring normal console event log display.
