CAUTION: Many repairs may only be done by a certified service technician. You should only

1. Verify that both the PSUs are the same type and have the same maximum output power.
NOTE: The maximum output power (shown in Watt) is listed on the PSU label.
2. If applicable, remove the PSU blank.
3. 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, relatch it. For information about the cable
management arm, see the system’s rack documentation.
4. 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: While installing, hot-swapping, or hot-adding a new PSU, 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.
