About Power Supplies

About Power Supplies

A power distribution board delivers DC power for all internal system components. The system’s power supplies plug in to connectors on this board, and when both supplies are installed, they 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 front of the system, as shown in the following figure.

Power supply 1	Power supply 2
DC status (green)	(option)
DC status (green)
Fault (yellow)
AC present status (green)

The system can accommodate one or two power supplies. Each power supply provides up to 380 watts of DC power. All system configurations can operate with only one power supply installed.

You can use a second supply to provide redundancy, allowing the system to continue operating should one of the power supplies fail. If your server includes a second power supply, connect the second AC power cord to the left inlet (labeled 2 on the back panel). You may connect the second power supply to the same AC circuit as the first supply. However, for increased system redundancy you should connect each power supply to a separate circuit.
