	BL p-Class power enclosure provides external, shared hot-plug power. Each three-phase power
	enclosure houses up to six hot-plug power supplies each single-phase power enclosures hold up
	to four hot-plug power supplies to power the BL p-Class server blades and interconnects
	Please use the sizing utility to determine the power needed for each configuration
	http://h30099.www3.hp.com/configurator/powercalcs.asp.
	Power enclosures and power supplies are not needed if using facility DC (-48V DC ± 10%). If
	using facility DC, only Facility DC Power Connection kit part number (240563-B21) is needed.
BL p-Class Power	In the ProLiant BL p-Class infrastructure, redundant -48 VDC power (from the power enclosures or
Distribution	facility DC power) is distributed from the power enclosures to the server blade enclosures through
	the bus bar system. Hinges attach the ProLiant BL bus bars to the rails in a rack. The bus bars
	swing open from the center to enable easy rear access to the server blades and network cables.
	Power is distributed redundantly through independent A- and B-sided bus bars.
	Three different power distribution solutions are available depending on the maximum number of
	server blade enclosures planned for the rack:
	ProLiant BL p-Class scalable bus bar
	ProLiant BL p-Class mini bus bar
	NOTE: To support a full 42U rack of BL20p server blades (6 server blade enclosures), two mini
	bus bars are needed.
