78 Installing System Components
NOTICE: To ensure proper system cooling, the power supply blank must be
installed on the unoccupied power supply bay in a non-redundant configuration.
See "Installing the Power Supply Blank" on page80.
Removing a Power Supply NOTICE: 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.
NOTE: On your rack system, 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 Installation Guide.
