Re: wireless controller image corrupted

Hi Chee,

It would be best to open a TAC Case for this. For other WLC Models this is a fatal error;

CSCsd52483

Controller stuck at grub> prompt

Symptom:

A WLC2006, WLC2106 or NM-AIR-WLC6 may seen to display a "grub>" prompt on the console port. It will be unable to boot the

WLC software and will not be able to operate normally.

Workaround:

Replace the hardware.

Hope this helps! And best of luck.

Rob
