After working inside your system
Power supply units
Your system supports two 1100 W AC power supply modules.
When two identical PSUs are installed, the PSU configuration is redundant (1 + 1) for each server sled. In
redundant mode, power is supplied to the system equally from both PSUs to maximize efficiency.
NOTE: If two PSUs are used, they must be of the same type and must have the same maximum
output power.
NOTE: For AC PSUs, use only PSUs with the Extended Power Performance (EPP) label on the back.
Mixing PSUs from earlier generations of Dell servers can result in a PSU mismatch condition or
failure to turn on.

CAUTION: The system requires one PSU for normal operation. On power-redundant systems,
remove and replace only one PSU at a time in a system that is powered on.
