Dell Precision Rack 7910 Owner's Manual

Removing an AC power supply unit

Prerequisites

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.

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.

Steps

Disconnect the power cable from the power source and from the power supply unit you intend to remove and remove the cables from the strap.
Press the release latch and slide the power supply unit out of the chassis.
