In the HP BladeSystem p-Class infrastructure, redundant -48 VDC power (from the power enclosures or
facility DC power) is carried from the power enclosures to the server blade enclosures through bus bars
(for multiple enclosures) or power bus boxes (for a single enclosure). Hinges attach the HP BladeSystem
bus bars to the rack rails and provide easy rear access to the blade enclosures and interconnects. Power
is distributed through independent A- and B-sided bus bars.
Three power distribution solutions are available depending on the size of the intended deployment (see
table).
