ProLiant BL p-Class Power
Enclosure
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.
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 Distribution
In the ProLiant BL p-Class infrastructure, redundant -48 VDC power (from the power enclosures or facility DC
power) is distributed from the power enclosures to the server blade enclosures through the Compaq 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:
•
Compaq ProLiant BL p-Class scalable bus bar
•
Compaq 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.
