Cisco Cisco 2504 Wireless Controller 릴리즈 노트

 lists the components that are upgraded after you install FUS.

Ensure that there are no power outages during the upgrade. Power outages during the upgrade might lead 
to the controller not being usable.

This release of FUS is applicable only to Cisco Wireless LAN 2500 Series Controllers.

You must install FUS only once.

Although console access to the controller during the upgrade process is not required, we recommend 
that you have the console access so that you can monitor the progress of the process.

The FUS upgrade process reboots the controller several times and reboots the default runtime image. 
The whole process takes approximately 30 minutes.
