POST Code Diagnostic LEDs
Eight amber POST code diagnostic LEDs are located on the back left edge of the server board
in the rear I/O area of the server board by the QSFP connector.
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 board. To assist in troubleshooting a system hang during the
POST process, you can use the Diagnostic LEDs to identify the last POST process executed.
For a complete description of how these LEDs are read and a list of all supported POST codes,
refer to Appendix D. (Table 89 refers to InfiniBand* LEDs for Link and activity status.)
