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.
