Facility DC power connection

Facility DC power requires a Facility DC Power Connection Option Kit to distribute the current through

the mini or scalable bus bars to the server blade enclosures. The HP BladeSystem p-Class system

requires –48 VDC with no more than ±10% voltage variance. If using facility DC power, power

supplies and power enclosures are not needed for operation, because the DC Power Connection

Option Kit provides power through a direct connection to the bus bars.

The HP BladeSystem p-Class solution is designed for AC input power from either single-phase or

three-phase power sources. Three-phase power supports maximum density configurations and is

highly recommended.

Geography and number of AC phases dictate the appropriate model of 3U power enclosure for the

data center. Each model of 3U power enclosure uses a different connector, as detailed in the

following chart. Additionally, each 3U power enclosure requires two separate 30 A power feeds.
