in the case of the Solarwinds TFTP server, the path is “/”.

Step 11 Repeat Step 8 to Step 11 to install the remaining file (either the 4.2 controller software or the Cisco

Unified Wireless Network Controller Boot Software 4.2 ER.aes file).

Step 12 Enter reset system to save the code update to non-volatile NVRAM and reboot the controller. The

controller completes the bootup process.

Step 13 Enter config wlan enable wlan_id to re-enable the WLANs.

Step 14 Re-enable your 802.11a and 802.11b/g networks.

Step 15 If desired, reload your latest configuration file to the controller.

Step 16 To verify that the 4.2 controller software is installed on your controller, enter show sysinfo and look at

the Product Version field.

Step 17 To verify that the Cisco Unified Wireless Network Controller Boot Software 4.2 ER.aes file is installed

on your controller, enter show sysinfo and look at the Bootloader Version field. “N/A” appears if the

ER.aes file is installed successfully. “Error” appears if the ER.aes file is not installed.

Note You can use this command to verify the boot software version on all controllers except the 2106

because the bootloader is not upgradable on the 2106 controller.
