Removing a Power Supply

CAUTION: The system requires one power supply to operate the system normally. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on.

1Disconnect the power cable from the power source.

2Disconnect the power cable from the power supply and remove the Velcro straps that bundle and secure the system cables.

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.

3Pull the power supply straight out to release it from the power distribution board and clear the chassis.

If you are permanently removing the power supply, you must install a power supply blank to ensure proper system cooling. See "Installing the Power Supply Blank" on page 157.
