Power Supplies
Your system supports one or two power supplies rated at an output of 750 W. If only one power supply is installed, it must be installed in the left power
supply bay (1). If two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.
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

Removing a Power Supply

NOTICE: The system requires one power supply for the system to operate normally. The system is in the redundant mode when two power supplies
are installed and both power supplies are connected to an AC power source. Remove and replace only one power supply at a time in a system that is
powered on. Operating the system with only one power supply installed and without a power supply blank installed for extended periods of time can
cause the system to overheat.
NOTICE: If only one power supply is installed, it must be installed in the left power supply bay (1).
NOTICE: If you connect the system to a power source in the range of 120 to 220 VAC, and if two power supplies are installed, the second power supply
serves as a redundant, hot-plug power source.
NOTE: On your rack system, you may have to unlatch and lift the cable management arm if it interferes with power supply removal. For information
about the cable management arm, see the system's Rack Installation Guide.
1. If your system has a single power supply, turn off the system and all attached peripherals. For a redundant system, you can leave the system running
and proceed to the next step.
2. Disconnect the power cable from the power source.
3. Disconnect the power cable from the power supply and remove the cable from the cable retention bracket.
4. Release the locking tab on the left side of the power supply by pressing in toward the right, and rotate the power-supply handle up until the power
supply is released from the chassis. See Figure 3-8.
5. Pull the power supply straight out to clear the chassis.
