Steps
1. Verify that the power supply unit being installed is of the same type and has the same maximum
output power as the existing power supply unit.
NOTE: The maximum output power (shown in watts) is listed on the PSU label.
2. If installed, remove the power supply unit blank.
3. Slide the new power supply unit into the chassis until the power supply unit 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.
4. Connect the power cable to the power supply unit and plug the cable into a power outlet.
