	NOTE: 3 phase power enclosure options highly recommended for HP ProLiant BL30p server blade
	deployments.
	Power enclosures and power supplies are not needed if using facility DC (-48V DC ± 10%). If using

	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.

HP BladeSystem p-Class Power Distribution (only required with 3U power enclosures)

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).

	Power Enclosures Supported	Server Blade Enclosures	Max. Rack Space Occupied
		Supported
Scalable Bus Bar	1 or 2	up to 5	36U
Mini Bus Bar	1 or 2*	up to 3	24U
Power Bus Box	1	1	9U
	NOTE*: Dual power input kit for mini bus bar option (364565-B21) required to support two power
	enclosures.
	NOTE: To support a full 42U rack of BL p-Class server blades, use two stacked pairs of mini bus bars.
