In the box outside the rack room (just outside the door, to the right as 
you exit, behind a rolled up carpet, in a box in the back of a giant rack)
there are two more POE's.

One is an old giant wall-wart adaptor whose cord is spliced into a grey 
cat5-cable.  The end nearest the splice is the network end, and the other 
end is the Cisco AP end.

The other is a Cisco POE injector, duct-taped to a power supply which 
accepts a type-O laptop power cord for AC.  It has two ports labeled 
Network and Device, Device being the Cisco AP.  This one is very similar 
to the one being used on the robot at the moment, iirc.
