Cisco Cisco 2504 Wireless Controller 릴리즈 노트

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.

The FUS image is applicable only to the following controller platforms in this release:

Cisco 2504 Wireless Controller

Cisco Flex 7510 Wireless Controller

Cisco 8510 Wireless Controller
