I have a 3750-48-ps that I've had unplugged for a couple of months, went to plug it in yesterday and nothing happened... No lights or anything.
Wondering if part of the AC part of the power supply went out I went and tried the DC connector, and nothing...
Ended up putting it on my desk and plugged it in, cycled it about 1/2 hour later and it comes right up and has been fine ever since. Even left it unplugged for the evening and when I came in it's fine.
I'm glad it isn't dead, but curious if anyone else has seen this behavior.
I've opened the cover and don't see any batteries on the board, maybe there is a battery in the rectifier that had run out?
