Power Supplies
Your system supports one or two power supplies rated at an output of 930 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.
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.
NOTE:
On a 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 supply 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, open the
handle, and slide the power supply out of the chassis. See Figure 3-10.
