This document illustrates the methods used to upgrade an Access Point (AP) that runs VxWorks firmware

browser or from a file server.

There are no specific requirements for this document.

The information in this document is based on VxWorks firmware version 12.01T1 upgraded to the VxWorks
firmware version 12.05. This upgrade procedure uses a 1200 AP that runs VxWorks firmware image 12.01T1.

An AP firmware image file is required to upgrade firmware through the AP console.

Note: Refer to Wireless LAN Downloads for the latest versions.

The file to download is a single file (AP12xxvxxxx.exe, a self−extracting archive).

The file must be extracted again, which results in an uncompressed image (AP12xxvxxxx.img) file.

Note: The .img file is what is installed on the AP, not the .exe file.
