Removing AC PSU

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 PSU for normal operation. On power-redundant systems,
remove and replace only one PSU 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 PSU
removal. For information about the cable management arm, see the system's rack documentation.
Steps
1. Disconnect the power cable from the power source and from the PSU you intend to remove and
remove the cables from the strap.
2. Press the release latch and slide the PSU out of the chassis.
