Admins,
Thanks for all responses, there have been quite a few. The overall
consensus is to use show power at the 3 character prompt.
>>>show power
I did this and found nothing logged in as an error.
The system went down last night again. I am running Performance Manager to
alert me if I get a power, fan, and/or high temp alert. I was really
praying that it would catch something...but I had little hope. This morning
I checked the power supply visually and to my surprise found the production
system was running only one power supply So I got a spare from supply and
installed another. I did notice that the upper connector on the first power
supply had a loose ground (black) connector ( It was seated high, where you
could see metal above the plastic) I pushed it back in. I'm not sure if
this wasn't from my installation of the second power supply. When I powered
it up all seemed well; while wheeling it back in to place though, I got a
bad power supply 1 error. I issued a show power and it said all was well
with an entry for the previous failure. So I unplugged the old power supply
to see what would happen. I got bad power supply 0 error, then I unplugged
the new one. It reported bad power supply 1. So either the power cable
wiggled out and in or their may be a problem upstream/downstream from the
power supplies.
Does any one know where I can get a detailed diagram (schematic of a 4100).
Here is a list of the following items that were mentioned that could also be
failing.

1. overtemp
check SRM logs: >>> show power
>>> more el
***Note I will also use more el if the system goes down again
2. faulty power switch
believe it or not, it happens.

You might have a problem with an interlock switch. They can be overriden
if necessary, your local compqq tech shou8ld be able to talk you through
it.

Some things to consider, real or imagined over-temperature
conditions, real or imagined power supply problems, or a
bad cabinet panel switch (I assume the systems powers itself
off when certain panels are removed to get into the guts
of the system).
FROM: John J. Francini [francini_at_zk3.dec.com]
Does this system have only a single power supply? I've seen that
before when a power supply was beginning to go bad, or if there's an
overtemp condition, or if one of the three microswitches is going bad
that cut power when the PCI/power/main card bay covers are removed.
It would just randomly power the system off. Have you checked the
console power events log?

We had this happen here.. it was the machine protecting itself from overheat
since one of the CPU fans quit.. do a show power from SRM to see if it
reports anything...
