Basic power control for HP BladeSystem p-Class and c-Class servers
This article provides an overview of the power circuits for HP BladeSystem and explains the reasons for different design choices
made for p-Class and c-Class.
HP BladeSystem p-Class power structure
This solution was not integrated into a single mechanical enclosure as is found in c-Class. In its maximum configuration, the p-
Class power architecture provided for two power enclosures, two external bus bars, and five server enclosures. This
configuration is shown in Figure 4-1. Power is distributed to the attached server enclosures at -48 VDC through DC power
cables and bus bars.
