Problems
The optional redundant power supplies in Dell Power-
Edge 4200 systems are controlled by the power supply
paralleling board. If a power supply paralleling board is
installed, the two indicators on the back of the power sup-
ply (see Figure 7-6) signal the status of the power supply.
If the red power-supply fault indicator lights up, the
power supply should be replaced.
