Cisco 5508 WLC Software Upgrade and Initial Configuration


1. First step would be to assign IP address and setup password for GUI where more advanced configuration would be done. Power on Controller and use Console cable to connect to controller. It will guide through the basic tasks of assigning IP Address, Subnet Mask and Gateway and admin username/password. It will force you to select other options as domain, DHCP server etc which you can set at this point but can change later so enter whatever you like for these. Once IP address is assigned to the controller. You can connect your laptop, assign it an IP address from the same range and access the GUI using web browser on the IP address assigned to WLC.

2. After entering the admin username and password you will be greeted with the following page which will display the current version of software running.

3. Now, the first thing we will do is to upgrade the running software on the controller from 6.0 to 7.2. The upgrade involves upgrading the software and also Field Recovery Image which is used when you want to use the

boot menu such as restoring to backup version or other boot options. Download the latest controller software from Cisco website, setup a TFTP server on your machine and set the home directory to where you have downloaded the files. We will use the controller GUI to download the latest software on controller. Select Command>Download File option as shown in the screenshot below
