Dell HR675 owner manual Removing a Redundant Power Supply

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.

1Disconnect the power cable from the electrical outlet.

2Disconnect the power cable from the power supply and remove the power cable from the cable retention bracket.

3Press the locking tab in toward the center of the power supply, then lift power supply handle to release the power supply from the chassis.

4Using the power supply handle, pull the power supply straight out of the chassis.
