Power supply options

Power supply redundancy

By default, the server is configured for 2 + 2 power redundancy. To review or update this setting in UEFI System Utilities, see Setting the server power supply requirements.

Population rules

The server supports installation of two or four power supplies. The power supplies are supported horizontally for redundancy. Observe the following when installing power supplies:

Two power supply configuration

  • Install 1600 W power supplies into power supply bays 1 and 2. Bays 3 and 4 are not supported in this configuration.

  • For 1 + 1 power redundancy, connect the power supplies in bays 1 and 2 to separate AC circuits.

    For information on cabling the power supplies for redundancy, see Installing a hot-plug power supply.

Four power supply configuration

  • Install power supplies into power supply bays 1—4.

  • For redundancy, connect AC power from one power circuit to power supplies 1 and 2, and then connect power supplies 3 and 4 to a separate AC power circuit.
