3.4 Power supplies
A minimum of two and a maximum of six power supplies can be installed in the
Enterprise Chassis (Figure 3-5). All power supply modules are combined into a
single power domain in the chassis, which distributes power to each of the
compute nodes and I/O modules through the Enterprise Chassis midplane.

The power supplies are 80 PLUS Platinum certified and are rated at 2500 W
output rated at 200 VAC, with oversubscription to 3538 W output at 200 VAC. A
C20 socket is provided for connection to a power cable, such as a C19-C20.
The 80 PLUS Platinum standard is a performance specification for power
supplies used in servers and computers. To meet this standard, the power
supply must have an energy efficiency rating of 90% or greater at 20% of rated
load, 94% or greater at 50% of rated load, and 91% or greater at 100% of rated
load, with a power factor of 0.9 or greater. Further information about the 80 PLUS
Platinum standard is at the following website:

The Enterprise Chassis allows configurations of power policies to give N+N or
N+1 redundancy.
