Intel® Light-Guided Diagnostics Intel® Server Board S5500WB TPS 8.5 POST Code Diagnostic LEDs Eight amber POST code diagnostic LEDs are located on the back edge of the server board in the rear I/O area of the server board by the VGA 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 A. Figure 26.

POST Code Diagnostic LEDs
Eight amber POST code diagnostic LEDs are located on the back edge of the server board in
the rear I/O area of the server board by the VGA 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 A.
