At one point yesterday, after I installed the
replacement bulkhead, I
could get the system to go though its diagnostics and end at '3' on the
numerical readout, which was the expected behavior. Later that evening,
I tried powering it up again, at which point it hung at '9', and
wouldn't progress any further. I went ahead and made up a console cable
with the pinout found at
[http://www.mcmanis.com/chuck/computers/vaxen/panels.htm] but the system
still hangs at '9'. Anyone know what might be happening? Of course, I
double checked the power supply voltages, which were ok, as well as
reseated boards/connectors, but still no go.
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.
