Figure 8-1 Download File to Controller Page

Step 7

From the File Type drop-down box, choose Code.

Step 8 In the IP Address field, enter the IP address of the TFTP server.

Step 9 The default values of 10 retries and 6 seconds for the Maximum Retries and Timeout fields should work

fine 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 field and the amount of time (in seconds) that the TFTP server attempts to download the software

in the Timeout field.

Step 10 In the File Path field, enter the directory path of the software.

Step 11 In the File Name field, enter the name of the controller software file (filename.aes).

Step 12 Click Download to download the software to the controller. A message appears indicating the status of

the download.

Step 13 Repeat Step 6 to Step 12 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 14 After the download is complete, click Reboot.

Step 15 If prompted to save your changes, click Save and Reboot.

Step 16 Click OK to confirm your decision to reboot the controller.

Step 17 After the controller reboots, re-enable the WLANs.

Step 18 Re-enable your 802.11a and 802.11b/g networks.

Step 19 If desired, reload your latest configuration file to the controller.

Step 20 To verify that the 4.2 controller software is installed on your controller, click Monitor on the controller

GUI and look at the Software Version field under Controller Summary.

Step 21 To verify that the Cisco Unified Wireless Network Controller Boot Software 4.2 ER.aes file is installed

on your controller, enter the show sysinfo command on the controller CLI 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.
