Cisco Cisco Wireless Services Module 2 (WiSM2)

If you are using a TFTP server, the default values of 10 retries for the Maximum Retries text field, and 
6 seconds for the Timeout text field should work correctly without any adjustment. However, you can 
change these values if desired. To do so, enter the maximum number of times that the TFTP server 
attempts to download the software in the Maximum Retries text box and the amount of time (in 
seconds) that the TFTP server attempts to download the software in the Timeout text box.

In the File Path  text box, enter the directory path of the software.

In the File Name  text box, enter the name of the controller software file (for example, 
AIR-CT5500-K9-1-9-0-0-FUS.aes).

If you are using an FTP server, follow these steps:

In the Server Login Username text box, enter the username to log into the FTP server.

In the Server Login Password text box, enter the password to log into the FTP server.

In the Server Port Number text box, enter the port number on the FTP server through which the 
download occurs. The default value is 21.

Click Download to download the software to the controller. A message appears indicating the status of 
the download.

After the download is complete, click Reboot.

If prompted to save your changes, click Save and Reboot.

Click OK to confirm.

After the controller reboots, repeat step 6 to step 17 to install the remaining file.

Reenable the WLANs.

For Cisco WiSM2, reenable the controller port channel on the Catalyst switch.

If you have disabled the 802.11 networks in Step 4, reenable them.

To verify the controller software version, choose Monitor  on the controller GUI and see Software 
Version  in the Controller Summary area.
