ProLiant BL p-Class
Power Enclosure
3U (5.25-inch), 19-inch wide, 29-inch deep (0.48-meter wide, 0.74-meter deep), dual input single phase and three
phase models available.
BL p-Class power enclosure provides scalable rack-centralized, hot-plug power without the need for PDUs.
Each 3 phase power enclosure houses six hot-plug power supplies
Each single-phase power enclosure holds four hot-plug power supplies
Please use the sizing utility to determine the power needed for each configuration
NOTE: 3 phase power enclosure options highly recommended for BL30p deployments.
Power enclosures and power supplies are not needed if using facility DC (-48V DC ± 10%). If using facility DC,
Facility DC Power Connection kit (240563-B21) is needed.
BL p-Class Power
Distribution
-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 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).
