Power supply units

Your system supports 350 W AC redundant power supply units (PSUs).

NOTE: If two PSUs are used, they must be of the same type and have the same maximum output power.

When two identical PSUs are installed, the PSU configuration is redundant (1 + 1). In redundant mode, power is supplied to the system equally from both PSUs to maximize efficiency.

When only one PSU is installed, the PSU configuration is non-redundant (1 + 0). Power is supplied to the system only by the single PSU.

In a non-redundant configuration, install a PSU blank in the empty PSU slot.
