This has reminded me of something that's bothered me the few times I've 
run into it. We have a stack of 3750Gs with a redundant power supply 
unit. When a power supply fails (or it's power feed fails), it correctly 
flips to the RPS. Now at this stage, even when power is restored, there 
doesn't seem to be a way to flip *back* to the mains power without 
pulling the plug on the RPS *and* the device that has flipped. The only 
UI on the RPS is a button that turns it off altogether...the manual 
doesn't say you can do this, but it doesn't say you can't either.

Am I dreaming?
