Ross,

Has the device came back online after the crash?

If no then there is a hardware issue and you have done the right job of creating the RMA for the same.

Thanks

No I went through the recovery procedure and tried to perform the emergency-install from rommon but as soon as it boots the recovery image it crashes again.

Got it. I would suggest no more troubleshooting go ahead with RMA and get a new box.
