The number of supported APs for non-5508 WLCs can be inferred from the model number of the corresponding controller.

For example, the AIR-WLC4402-12-K9 supports twelve APs, the AIR-WLC2106-K9 supports six APs, and the NME-AIR-WLC8-K9 supports eight APs.

WiSM controllers have two onboard controllers which each support 150 APs, for a total of 300.

You can add additional AP capacity through capacity adder licenses available at 25, 50, 100 and 250 AP capacities.

You can add the capacity adder licenses to any base license in any combination to arrive at the maximum capacity of 500 APs.

The base and adder licenses are supported through both rehosting and Return Material Authorizations (RMAs).

For instructions on how to obtain an upgrade license for the number of supported APs, refer to the Obtaining an Upgrade or Capacity Adder License section of the Cisco Wireless LAN Controller Configuration Guide, Release 7.0.

Once this has been done, refer to the Installing a License section of the Cisco Wireless LAN Controller Configuration Guide, Release 7.0 for the remaining steps.

Within 60 days you need to register the existing license for the new 5508.

It is a free and can be obtained from here: Ensure your TFTP server instance is running and pointed to a directory of your choice.

This directory should be where your firmware and FUS files are saved.

Ensure you have an inbound firewall created to allow incoming connections to your machine on UDP port 69 if you will be using the TFTP option.

Backup Your Configuration Using the CLI, enter these commands to save a copy of your config to your computer.

Once the firmware has finished updating, click on the Click Here link to reboot the WLC.

Click OK on the Configuration will be saved and the controller will be rebooted prompt.

Once the wireless LAN controller reboots, you should now be on the firmware version you provided.

Remember, the FUS upgrade could take 30-60 minutes of downtime.

It is also recommended that you connect to your WLC using the console port (micro-USB or RJ-45) and record the output in case you need to do some troubleshooting later.

You can use a tool like PuTTY to connect via Serial and change the Logging settings under Session to log All Session Output and specify a filename and location.
