FUS version on WLC 2504

caob — Mon, 05 Jul 2021 14:40:09 GMT

I need to upgrade a WLC 2504 to ver 8.3.122.0 but I see the following message "In order to use 8.3 or higher code, you must upgrade the 2504 Wireless Lan Controllers to FUS version 1.9 or higher, this must be done before installing the new AireOS version."

When I put the "show sysinfo" command, I recieve the following information:

(Cisco Controller) >show sysinfo

Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Product Version.................................. 8.0.140.0
Bootloader Version............................... 1.0.18
Field Recovery Image Version..................... 1.0.0
Firmware Version................................. PIC 16.0

Based on that, what is the FUS version on my WLC?

Regards

Thank you Scott, so I understand that at this moment my wlc is running FUS 1.8 and since I don't see any restrictions on upgrading FUS 1.8 to 2.0.0 there should be no problem if I jump straight to 2.0.0, right? This is in order to avoid the CSCuu46671 related to FUS 1.9.

You can upgrade directly to 2.0.0.0 without issues.
