76 Installing System Components
Removing a Redundant 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.
NOTICE: If you are replacing a redundant power supply while your system is
running, make sure that both the power supply status and the AC line status LEDs
are green before removing the power supply. See Figure 1-3 to identify the power
supply LEDs. If one or both of the LEDs are not green, see "Troubleshooting
Redundant Power Supplies" on page 171.
1
If your system has a single hot-plug 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 power supply by pressing in toward the
center of the power supply, and rotate the power-supply handle up until
the power supply is released from the chassis. See Figure 3-7.
5
Pull the power supply straight out to clear the chassis.
