All Powerful List,
I have an interesting case for you.... We have several P92 workstations,
foxboro part P0923LT, that have been experiencing failures. After analysis,
an outside party identified that the failure was due to failed (bulging)
electrolytic capacitors on the Dell P390, and replaced them. We're in a
difficult place in our lifecycle replacement, and are coming up with a
bridging strategy between our current setup and a future setup, this is a
big problem in that strategy.
Has anyone else on the list experienced this failure? If so, was there
more detail on what failed, why it failed, and how to prevent similar
failures?
My concern is that replacing the capacitors may be a stopgap, and that
there may be other factors involved in the failures. For instance, if the
power supply isn't providing power to the motherboard at spec, it may
affect capacitor reliability. Humidity and temperature may also
contribute, as may storage of these systems when not in use. Also, these
capacitor failures may have other unintended effects elsewhere in the
system.
So, basically I'm asking for your experience and some ideas on what might
be going on. Thanks!
