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.
