System troubleshooting

TroubleAction

The system does not boot and appears dead. The system does not emit any beeps. The fans do not turn.

Verify that the power cord is properly plugged in the power outlet.

Check if other equipment plugged in the same power outlet works.

Note: If the fans are turning, but the system emits no beeps, verify that:

The monitor is turned on.

The power cord to the board (processor and main) is plugged in correctly.

The system does not start, but emits beeps.

Identify the type of beeps that your system emitted: system board beeps or RAID beeps.

The system board beeps are usually short; their pattern is identified in the 703t Server Maintenance and Diagnostics guide (NN44200-702). The system board beeps are usually not associated with information displayed on the screen. If the system does not display information on the screen but emits board beeps, then a main board condition is present.

The RAID beeps are high-pitched and long. The RAID beeps emitted by the system during startup are associated with messages indicating that a system is in a critical state.

Check the status LED at the front for a blinking or steady amber light, which indicates that:

A critical temperature or voltage fault has occurred.

The CPU was not installed or is not functioning.

Check the beep codes provided in the 703t Server Maintenance and Diagnostics guide to identify the failure, and then replace the defective component or remedy the fault.
