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 came with the product.
CAUTION: The system requires one power supply for normal operation. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on.
NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power supply 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 power supply unit you intend to remove and remove the cables from the strap.
Press the release latch and slide the power supply unit out of the chassis.
Installing an AC power supply unit:
Verify that both the power supply units are the same type and have the same maximum output power.
NOTE: The maximum output power (shown in watts) is listed on the PSU label.
If applicable, remove the power supply unit blank.
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.
Connect the power cable to the power supply unit and plug the cable into a power outlet.
CAUTION: When connecting the power cable, secure the cable with the strap.
