Installing A Power Supply

CAUTION: Ensure that both power supplies are of the same type and have the same maximum output power.

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

1.Slide the new power supply into the chassis until the power supply is fully seated and the release latch snaps into place.

NOTE: If you unlatched the cable management arm in step 2 of the previous procedure, relatch it. For information about the cable management arm, see the system’s rack documentation.

2.Connect the power cable to the power supply 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 power supply in a system with two power supplies, allow several seconds for the system to recognize the power supply and determine its status. The power-supply status indicator turns green to signify that the power supply is functioning properly.
