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

This release of the Field Upgrade Software is applicable to Cisco WLCs that are installed with the controller software release 6.0 and later.

You must install the FUS image only once.

Console access to the WLC during the upgrade process is not required. However it is recommended that you have console access so that you can monitor the progress of the process.

The FUS upgrade process reboots the Cisco WLC several times, and reboot the default runtime image. The whole process takes approximately 30 minutes.

After you install the FUS image for a Cisco Flex 7500 Controller platform, the RAID firmware is also upgraded. During the installation process, the console messages displayed do indicate upgrade of the RAID firmware. However, it is not possible to verify the RAID firmware upgrade either by entering a command or viewing the bootlog.
