[I_Still_Know!]

I know the feeling you are talking about. It is similar to the 'shit, did i just lock my keys in the car\house?' shiver.

I have never done anything that bad.

Although a couple of years ago I was working as a Desktop Support person. My first IT job straight out of TAFE.

Anyway, I went into the server room around midday to do something and could hear a constant beeping. I searched around the room and noticed that it was coming from one of the UPS's (I assume you all know what that is).

Anyway, I thought about it for a second and came to the conclusion that UPS's just kick in if a power failure ever occurs and decided to turn it off and then back on again to stop the damn beeping noise that was coming from it.

So I turned it off and then back on and looked for the cable that I originally went in there for, when my boss bursts through the door and asks what just happened.

I told him what I did and he quickly explained by doing what I did that I had just shut down all print and file servers for the whole site. And explained that all the power for the servers run THROUGH the power supply. You turn it off and you turn them off.

There was no major damage caused, but just very embarrassing.
