Power Supplies

Your system supports the following power supply modules:
• 350 W (non-redundant power supply)
• 400 W (redundant power supply)
If two power supplies are installed, the second power supply provides
hot-swappable, power redundancy. In redundant mode, the system distributes
the power load across both power supplies to maximize efficiency. When a
power supply is removed with the system powered on, the full power load is
picked up by the remaining power supply.

Removing a Redundant Power Supply

CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.
CAUTION:
The system requires one power supply for normal operation. On
power-redundant systems, remove and replace only one power supply at a time in
a system that is powered on.
