When ordering servers from HP, you can specify whether you want AC-power adapters (110 - 230Vac) or 48Vdc-apapters.
Only catch is that you have to be carefull that in telco-stuff the plus is grounded, while other equipment (like RF-transmission) use negative-grounding.
Unless you are fond of sparks and welding, you're in for a nasty surprice..
A coworker once fell down from a... what do you call it, a portable stairs, when he was connecting power at a exchange, with a screwdriver on his hands. This fell across the two naked dc lines... after some sparks an entire island resulted without cellular coverage for some hours :-} I wonder, those servers you mention, can be adapted to both type of grounding? And how is the price compared to ac power unit, if you remember? Not a figure, just curious to know if they are more expensive or not. - -- Cheers, Carlos E.
