Cisco 2811 not booting

Hi,

A client has 2x2811 acting as Voice Gateway and backup Voice Gateway and both, after some undisclosed circumstances, are not booting.

After some troubleshooting a faulty memory DIMM was detected on the primary Voice Gateway. Still, DIMM replaced, it continued failing to boot. Tried the other router and the symptom was the same:

Cabvg010

Expected a checksum of 0xC117781E

I tried changing the boot sequence, uploading a new version via tftpdnld,15.1(4)M8 (verifying that the checksum on the file was the same as on Cisco CCO), formatting the flash. All failed.

As of now, I have no more solutions to turn on to.

Has anyone faced a similar problem able to provide some help?

TIA,

Pedro Miguel Marques

I strongly recommend you get the chassis replaced.  If you don't have a valid maintenance contract, don't despair, you still got some home.  Contact your nearest Cisco AM/SE and show them the document above.  Initially, they might feign ignorance but they are to honor all complaints.

If the DIMM was replaced, and

If the DIMM was replaced, and the device still failed to boot, it wouldn't be the field notice mentioned... unless the memory installed was bad.

Also, the field notice has nothing to do with whether or not your parts are covered by a contract or not. Some field notices are of that nature (a recall) but this one is not.
