7.5 Post Code Diagnostic LEDs
During the system boot process, 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, BIOS will
display the given POST code to the POST code diagnostic LEDs found on the back edge of the server
board. To assist in troubleshooting a system hang during the POST process, the diagnostic LEDs can be
used to identify the last POST process to be executed. See Appendix C for a complete description of
how these LEDs are read, and for a list of all supported POST codes.
