Dell PowerEdge R320 Systems Owner's Manual

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.

Disconnect the power cable from the power source.
Disconnect the power cable from the power supply and remove the straps that bundle and secure the system cables.
- NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power-supply removal. For information about the cable management arm, see the system’s rack documentation.
Press the release latch and pull the power supply straight out to release it from the power distribution board and clear the chassis.
