Ok turns out this
was the same cabinet that had the UPS that was shocking people, but when it was removed, we didn't get any reports of shocks.
I went to the maintenance area and told them I think we had an open ground and was told to e-mail the supervisor. They called me a few minutes ago and said the was no continuity between the cabinet (which has several bare metal power supplies mounted to it) and the ground pin on the outlet strip that the computer was plugged into.
So apparently when they were asked last night to check the cabinet out to make sure it was safe for me to stick my hands into, they saw the computer, and didn't check it.
They seem to have a fear of computers. We have another area with a device that has a pneumatic release mechanism. The mechanism is just to make sure a particular board is locked into place during firmware programming. They hold the button and insert the board, and when they release the button, air pressure causes the claws to retract pulling the board all the way in to the programming header. When programming is done, they press the button, the claws release, and a spring loaded pin pushes the board back out.
I'm about 90% sure that button has no electrical connection, it's just a mechanical valve. Yet every time they have a problem with the boards not releasing, they call for IT to look at it and then we have to have maintenance look at it because we hear a loud hissing from behind the unit. And a few hours will pass and we'll get another call saying it still isn't working. When we ask them if maintenance looked at they'll say "They told me it was a computer problem"
