For some reason, or maybe I was unlucky, too, DS10s (or their
PSUs) appear to be prone to electrical issues, especially
after power failures.

I remember one of my DS10s had worked fine but from some time
onward, after one or more power failures, it began to exhibit
unpredictable behavior.  It would power up, run, etc., but I
would get bizarre errors under VMS, with no explanation for
it in the logs.  The kind of errors you may also expect from
memory faults, but I swapped the memory (and also the disk)
between my DS10s and the problems were really specific to
one DS10.

My conclusion was at the time that perhaps the PSU wasn't in
order and, just like now, they're relatively hard to come by,
not to mention quite costly.

Reparing a PSU can be quite dangerous and one has to be
careful, but that hopefully goes without saying.
