Dell PowerEdge 2950 User Manual

Installing System Components 63
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.
