Hi Chee,

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


Controller stuck at grub> prompt


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.


Replace the hardware.

Hope this helps! And best of luck.
