Ok... I think this was the server that was damaged. Couldn't get confirmation (no one was around) but it was pulled away from most of the other racks...
This is the machine that they smacked into that started arcing. Evidently the technical name for it is an "AC unit." Heh.
At least, that's what I assume it is...
Exciting stuff, Huh?
Sorry the photos are all sideways...taken with an iphone and I am far too lazy to adjust.
