Step-by-Step Instructions

Complete these steps:

1. Complete these steps in order to log into the controller through your browser:

   1. HTTPS to the management IP address of your controller (for example, https://10.77.244.204).

      You are prompted for user credentials.

   2. Enter the username and password of the controller and click OK.

      The default username and password on the WLC are both admin.

      The Monitor window appears. The Controller Summary information shows you the current software version that runs on the WLC.

      

2. Complete these steps in order to define the download parameters for the software upgrade:

   1. Click Commands in the menu at the top of the window.

      The Download File to Controller window appears.

   2. Enter the download parameters.

      The parameters to define include:

      • TFTP server IP Address

      • File Path

      • Maximum retries

      • Timeout

      • File Name

      The parameters used in this example are:

      • TFTP server IP Address—10.7.244.204

      • Maximum retries—10

      • Timeout—6

      • File Path—./

      • File Name—AIR-WLC4400-K9-5-2-178-0.aes

   3. Click Download in order to start the upgrade process.

      Here is an example:

      

      Note: When you perform the upgrade from the GUI, for File Path, you can insert a dot (.) as long as the image is in the root directory of your TFTP server. This way, you do not have to enter the path were the image is saved.

3. Reboot the system after the file transfer is complete in order for the new software to take effect.

   Click Click Here in order to reboot, as this example shows:

   

4. In the the System Reboot window, click Reboot at the top right side of the window.

   

5. Click Save and Reboot in the Reboot System > Save window.

   

   After the reboot, you can log back into the controller and verify that the new version runs.

   Note: The new version is 4.1.170.0.

   

6. Upgrade the boot image (version 4.1 and later version upgrades only). The procedure is identical to steps 1 through 5 of this procedure, except you load the AIR-WLCxxxx-K9-5-2-157-0-ER.aes image.
