PLUS,  with PoE, any devices plugged in and configured for PoE, like 
access points and SIP phones will be powered by the UPS back in the 
computer room.  I did this in my new office.  We get occasional power 
outages lasting just a few seconds to a couple of minutes, and my access 
point and phone never skip a beat.

It's WAY cool.
