I had time to troubleshoot further, and somehow managed to get it to at
least make it to '6', but couldn't get it to progress past '9' the next
time (when I had a console cable connected). I'm starting to think there
may indeed be a power supply issue, but I won't know for sure for a few
more weeks at least. Is the power supply in the BA123 failure prone in
this manner, especially after being out of service for 6 years?
Also, what is the story on the FCO on the power harnesses for the
backplane? The two harnesses in my BA123 are made of a gray ribbon cable
pressed into orange connectors.
