Hello,
I've upgraded our WLC to 8.5.140.0 this weekend and all is good.
Cisco then said to do the FUS. So today I've uploaded 'AIR-CT5500-K9-1-9-0-0-FUS.aes' so we can reboot at the weekend.
However when I go to the WLC I see:
(Cisco Controller) >show boot Primary Boot Image............................... Error (default) Backup Boot Image................................ Error (active)
This doesn't look good does it?
Thanks

Hi,
That does indeed not look good. I would suggest opening a TAC case before rebooting the controller.
But I must say I have never done a show boot before a reboot for a FUS upgrade so this may be normal. But I would open a case eater case. Better safe then sorry in this case sens a faulty FUS upgrade will often result in a bricked WLC.
regards,
Jonas
