1 Connect to the device via console/SSH (If using Mobility express, connect to the device IP via SSH or console cable, not the Mobility Express controller IP address)
2 Login with correct credential
3 You will see “name of the device> ” in command window
4 Type “show version” to view current image information
5 From following image we can see currently the AP us running on “Primary Boot Image” which is “22.214.171.124” the “Backup Boot Image” is “126.96.36.199”
6 Now we need to login to “Cisco Controller”. For Mobility Express running as master or “Autonomous Mode” you can SSH to the IP address which you used to login to Mobility Express controller (See following image).
7 Enter following command, replce <AP_Name> with correct access point name
(Cisco Controller) >config ap image swap <AP_Name>
8 If there is no error message returned, reboot the AP.
After the AP rebooted, use the same “show version” command to check the booted image, now it should be swapped. (Or use Wireless LAN Controller Web UI to check current version number)
