WLC Boot Problem


Check out this FAQ:

Q.    The Cisco 4400 Series Wireless LAN Controller (WLC) will not boot. This   error message is received on the controller: ** Unable to use   ide 0:4 for fatload ** Error (no IRQ) dev 0 blk 0: status 0x51 Error reg: 10 **   Can't read from device 0...

A. The reason for this error might be a hardware issue. Open a TAC case to       further troubleshoot this problem. In order to open a TAC case, you need to       have a valid contract with Cisco. Refer to Technical Support in order to       contact the Cisco TAC.

You will need to contact your Cisco rep to progress.

WLC Boot Problem

Hi there..

We have encountered the same error on our WLC today and have raised a fault with TAC.

Did this turn out to be a hardware fault or was it fixable in the end ?..
