roubleshooting 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).
