The CPU is locked up and I have no comms. I've seen this before and usually it's a PMI module or board. I've pulled them all out and CPU is still locked up. Tried several different CPU boards and swapped chips, still same thing. Checked 5V & 12V, both good. Changed backplane, still same issue. Also, cleaned and reseated all boards, still same issue.

You need to connect with Hyperterminal and do a confidence test to see what the problem is
