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 centre 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.
