LED information
The system board in this server includes LEDs that can assist you in troubleshooting your
system. See the following table for a description of these LEDs and the information they
provide:
Diagnostic LEDs
The BIOS sends a 1-byte hex code to port 80 prior to each POST task. These codes are
displayed on four tri-colored LEDs, located on the system board and available at the back
of the server chassis. These codes can provide troubleshooting information in the event
of a system hang during POST.
