10.7 Post Code Diagnostic LEDs

Eight amber POST code diagnostic LEDs are placed in two rows and located on the back edge
of the server boards in the rear I/O area of the server boards by system ID LED and status LED.
During the system boot process, the BIOS executes a number of platform configuration
processes, each of which is assigned a specific hex POST code number. As each configuration
routine is started, the BIOS displays the given POST code to the POST code diagnostic LEDs
on the back edge of the server boards. To assist in troubleshooting a system hang during the
POST process, you can use the diagnostic LEDs to identify the last POST process executed.
See Appendix C for a complete description of how these LEDs are read and a list of all
supported POST codes.
