directed by the online or telephone service and support team. Damage due to servicing that is

Steps

power.

NOTE: The maximum output power (shown in watts) is listed on the PSU label.

2. If applicable, 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.
