The power supply unit (PSU) is an internal hardware component which
supplies power to the components in the system.
Your system supports one of the following:
Two 2400 W, 2000 W, 1600 W, 1100 W, 750 W, or 495 W AC PSUs
Two 1600 W, 1100 W, 750 W, 750 W Mixed Mode, or 495 W AC PSUs
Two 1100 W DC PSUs
Two 1100 W or 750 W Mixed Mode HVDC PSUs
NOTE:For more information, see the Technical specifications section.
CAUTION:If two PSUs are installed, both the PSUs must have the same type of label. For example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not supported, even if the PSUs have the same power rating. Mixing PSUs will result in mismatch condition or failure to turn the system on.
NOTE:Titanium PSU is nominally rated for 200 V AC to 240 V AC input only.
NOTE:When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilization is low in order to maximize efficiency.
NOTE:If two PSUs are used, they must be of the same maximum output power.
This section contains information about the hot spare features, wiring instructions for a DC power supply unit, removal and installation of the power supply blank, and AC power supply unit.
