Power supplies

The server supports up to two power supplies for redundancy.

The server does not support setting the redundancy mode manually. The BMC of the server can automatically set it based on the installed power supply unit quantity.

  • When only 1 power supply unit is installed, the power policy is set to Non-redundant mode.

  • When 2 power supply units are installed, the redundancy mode is set to Redundant N+N. If one of the power supply units fails or has been removed, the BMC will report an event and set the redundancy mode to Non-redundant mode automatically.
