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.
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
Pull 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.
