Figure 19 illustrates the c7000 enclosure power options.

Figure 19. c7000 enclosure power options

Moving the power supplies into the enclosure reduces the transmission distance for DC power

distribution and employs an industry-standard 12V infrastructure for the enclosure. By using a 12V

infrastructure, HP eliminated several power-related components and improved power efficiency on the

server blades and in the infrastructure. The control circuitry was stripped and put on the management

board and fans.

NOTE

The c7000 power module in the bottom rear of the enclosure

determines whether the enclosure operates on single-phase AC,

three-phase AC, or DC power. This choice is available when the

enclosure is ordered.

The enclosure can contain up to six 2250W self-cooled or 2400W self-cooled high efficiency power

supplies, for a maximum of 14400W output capacity per enclosure. The 2400W power supplies

provide higher efficiency to save energy—92% peak and over 88% efficient with as little as a 10%
