5/26/05 Updating OS Software from Cisco WCS
OL-7426-03
In the Download Software to Switch page, click the Browse button and navigate to the OS
code update file named AS_2000_<release_number>.aes for Cisco 2000 Series Wireless LAN
Controllers, or AS_4100_<release_number>.aes for Cisco 4100 Series Wireless LAN
Controllers, or AS_4400_<release_number>.aes for Cisco 4400 Series Wireless LAN
Controllers. (For example, AS_4100_3_0_60_0.aes.) The path and filename of the OS code
appear in the File Name box.
Click the Download button.
Cisco WCS downloads the OS code file to the Cisco WCS Server /aes-tftp directory, then down-
loads the OS code to the Cisco Wireless LAN Controller, and then the Cisco Wireless LAN
Controller writes the code to flash RAM. As Cisco WCS performs these functions, it displays its
progress in the Status box.
Refer to the Transferring Files To and From a Cisco Wireless LAN Controller section for other file upload
and download instructions.
CAUTION: MAKE SURE you have the correct OS code file:
• Cisco 2000 Series Wireless LAN Controller OS code files are named
AS_2000_<release_number>.aes.
• Cisco 4100 Series Wireless LAN Controller OS code files are named
AS_4100_<release_number>.aes.
• Cisco 4400 Series Wireless LAN Controller OS code files are named
AS_4100_<release_number>.aes.
