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 are shipped with your product.
CAUTION: The system needs one power supply unit (PSU) for normal operation. On power-redundant systems, remove and replace only one PSU at a time in a system that is powered on.
If applicable, unlatch and lift the optional cable management arm if it interferes with the power supply unit (PSU) removal. For information about the cable management arm, see the system’s rack documentation.
Removing an AC power supply unit:
Disconnect the power cable from the power source and from the PSU you intend to remove, and then remove the cables from the strap.
Press the release latch and slide the PSU out of the chassis by using the PSU handle.
Installing an AC power supply unit:
Slide the PSU into the chassis until the PSU is fully seated and the release latch snaps into place.
If applicable, relatch the cable management arm.
For information about the cable management arm, see the rack documentation of your system.
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, wait for 15 seconds for the system to recognize the PSU and determine its status. The PSU redundancy may not occur until discovery is complete. Wait until the new PSU is discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify that the PSU is functioning properly.
