This section describes the power-supply LEDs on the rear
of the server and the suggested actions to correct the detected problems.
The following minimum configuration is required for the server
to start:
- One microprocessor
- One 1 GB DIMM
- Power supply
- Power cord
- ServeRAID SAS/SATA adapter
- Five cooling fans
The following illustration shows the LEDs and connectors on the
rear of the fixed power-supply model.

The following illustration shows the LEDs and connectors on the
rear of the redundant power-supply model.

model
The following table describes the problems that are indicated by
various combinations of the power-supply LEDs and suggested actions
to correct the detected problems.
Table 1. Power-supply LEDs. The power-supply
LEDs table with two rows of column headings for the AC power-supply
LEDs combination of AC, DC, and Error, and one row of column headings
for the description, action, and notes.

Faulty system board or faulty power supply |
- Turn off the server and disconnect the power cord from the server;
then, reconnect the power cord.
- If the system board error (fault) LED is not lit, replace the
power supply.
- (Trained technician only) If the system board error LED is lit,
replace the system board.
