This issue of AC v DC and reliabilty of facilities is interetsting. We 
co-locate equipment at several telcos, and they co-locate equipment 
with us out west. We prefer DC wherever possible. This is because the Telcos 
don't depend upon anyone but themselves to provide reliable and clean power.
Another way of looking at it is that if the telco goes down, then the 
application layers above are useless.We just received the first of several 
7507s to that end....all DC. 

Our real problem is getting them to fit properly in 23" racks :)

While this may not apply to 7513s, we've found that super-sturdy $25
23" or 19" rack shelves (and Greybar sells the Chatsworth sturdy
shelves for $75 or so) take a 7507 or 7000 (or 7505/7010) *very* well,
and there's not need to bother with the rack-harnesses.
