The manufacturer states rather strongly that unplugging the UPS is a BAD
way to test it since that also removes the ground circuit. So far, my best
idea is to go out to the electrical box and flip the relevant circuit
breaker off.
The point though, is even that only tests the UPS. I would need to leave
it off long enough for the UPS to request (via that USB cable) that the
computer do an orderly shutdown which could take 30 minutes or more. And
worse, I would not know if a non-event meant a failure on the part of the
UPS signaling system or the Linux side not making use of the signal event
since I still have no idea what to check for.
I bring all this up because my last UPS failed to protect the computer so
now I am paranoid about it.
