88 Installing System Components
Removing a Power Supply
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.
1 Disconnect the power cable from the power source.
2 Disconnect 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.
3 Press the release latch and pull the power supply 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 89.
