About Power Supplies

A central power distribution board delivers DC power for all internal system

components. The system’s power supplies plug into connectors on this board, and

all of the supplies installed share equally in satisfying the power demands of the

system.

Power supplies are modular units, designed for fast, easy installation or removal,

even while the system is fully operational. Supplies are installed in bays at the rear

of the system, as shown in the following figure.

The system can accommodate a maximum of three power supplies. Each supply

provides up to 560 watts of DC power. Most system configurations can operate with

only one power supply installed. In this case, a second supply can be used to

provide N+1 redundancy, allowing the system to continue operating should one

of the power supplies fail.

Two supplies will provide enough power for a heavily configured system. In this

case, a third supply can be added for N+1 redundancy. With three power supplies

installed in the system, even a heavily configured machine can continue full

operation during removal or replacement of one of the supplies.

In a system with three power supplies, the third power supply is always redundant;

it cannot be used to increase output capacity.
