Troubleshooting Power Supply Problems

The optional redundant power supplies in Dell Power- Edge 6100 systems are controlled by the power-supply paralleling board. The two light-emitting diodes (LEDs) on the back of the power supply (see Figure 7-7) signal the status of the power supply. If the red power-supply fault indicator lights up, the power supply should be replaced.

Replacing a Power Supply

Follow these steps to replace a power supply.

CAUTION: If a power supply in this computer sys- tem fails, do not remove it from the system. The failed power supply must remain in the system until it can be replaced with a working power sup- ply. Failure to do so will cause the hard-disk drives to overheat.

1.Disconnect the AC power cable from the power outlet; then disconnect the other end of the cable from the power supply.

Open the plastic strain-relief clip and remove the AC power cable.

2.Turn the locking switch on the power supply to the “standby” position, marked by a partial circle with a line through the top.

3.Turn the locking knob counterclockwise to release the power supply.

4.Slide the power supply out of the chassis (see Fig- ure 7-8).
