Power supply units
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, or 750 W AC PSUs
•
Two 1100 W DC PSUs
•
Two 1100 W or 750 W Mixed Mode HVDC PSUs
NOTE:
For more information about power supply units, see the
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 result in mismatch condition or failure to turn on the system.
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 to maximize
efficiency.
NOTE:
If two PSUs are used, they must be of the same maximum output power.
NOTE:
In a single PSU configuration, install the PSU in bay 1 (bottom PSU slot).
