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 (CR22
to CR29) 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 CR22-CR25 comprise one group,
and LEDs from CR26-CR829 comprise the other group. The two groups represent the two digits
of the hex code. The CR22-CR25 group stands for the first digit and the CR26-CR29 group stands
for the second.
