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 on,
ensure that both the power supply status and the AC line status LEDs are green
before removing the power supply (see Figure 1-3). If one or both of the LEDs are
not green, see "Troubleshooting Redundant Power Supplies" on page 143.
1 Disconnect the power cable from the electrical outlet.
2 Disconnect the power cable from the power supply and remove the power
cable from the cable retention bracket.
3 Press the locking tab in toward the center of the power supply, then lift
power supply handle to release the power supply from the chassis.
4 Using the power supply handle, pull the power supply straight out of the
chassis.
