CHAPTER 6: Troubleshooting

Diagnostic LEDs

This system board provides a set of eight diagnostic (Port 80) LEDs. If you are troubleshooting your system, these LEDs can help you determine where errors are taking place.

If you are experiencing problems with your server, open the case and check these LEDs (CR8 to CR15) on the system board, then check the tables on the following pages to determine the problem.

The location of Port 80 LEDs is shown in the following illustration:

The eight diagnostic LEDs are divided into two groups. LEDs from CR15-CR12 comprise one group, and LEDs from CR11-CR8 comprise the other group. The two groups represent the two digits of the hex code. The CR15-CR12 group stands for the first digit and the CR11-CR8 group stands for the second.
