If installed, remove the PSU blank.
Steps
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, re-latch it. For information about the cable
management arm, see the system’s rack documentation.
Next steps
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 discover the PSU and determine its status. The power supply redundancy may not occur until
discovery is complete. Wait until the new PSU is discovered and enabled before you remove the old
PSU. The PSU status indicator turns green to indicate that the PSU is functioning properly.
