<p class="MsoNormal">I once worked for a provider who had a company next door that ran a small datacenter of about a dozen or so racks. They had been sold and all of their infrastructure had been virtualized and moved to the new owner�s network. The last
task of the local admin was to just get rid of everything. They didn�t care how just get it gone. So he came over and asked us to come take a look and we could have anything we wanted. I picked up a few servers for lab a bunch of racks and stuff.
<br>
<br>
While we were working I asked the guy �So there is absolutely nothing that�s in production in here anymore?� He said �Yep� so I asked �Then if the power went off in here it wouldn�t be a big deal� and he said �Not at all�. Then I asked �Can I hit the
red button?� He said �Sure, I always wondered what happened�. I hit the button and with a loud booming sound the room went dead silent and then the UPS started beeping. It was at that moment everyone realized that you just don�t pull the button
out to restart the room. It took us 20 minutes to figure out how to turn it all back on.
<br>
<br>
And with that when I got back to our office I made sure someone knew how to restart everything if we ever had to hit our red button.<o:p></o:p></p>

<p class="MsoNormal">Miy story in the late 1970s I was working in a large computer facility
<br>
with both mainframes and mil-spec 400hz computers.<br>
Management decided that the EPO should be tested. So we powered down <br>
the disk and tapes. The electrician pressed<br>
the EPO button and NOTHING. Everything kept running.<br>
<br>
Turns out a wire had come loose and the fuse in the EPO circuit had blown.<br>
