Installing a redundant 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.
Ensure that you read the Safety instructions.
Steps
1. Verify that both PSUs are the same type and have the same maximum output power.
NOTE: The maximum output power (shown in Watts) is listed on the PSU label.
2. Slide the new PSU into the chassis until the PSU is fully seated and the release latch snaps into place.
NOTE: If you unlatched the cable management arm in step 3 of the previous procedure, relatch
it. For information about the cable management arm, see Installing the cable management arm
(CMA).
3. Connect the power cable to the PSU and plug the cable into a power outlet.
CAUTION: When connecting the power cable, secure the cable with the strap.
NOTE: When installing, hot-swapping, or hot-adding a new PSU in a system with two PSUs,
allow several seconds for the system to recognize the PSU and determine its status. The PSU
status indicator turns green to signify that the PSU is functioning properly.
