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.

the “standby” position, marked by a partial circle
with a line through the top.

ure 7-8).

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.
