Server System H2000WP Family TPS Appendix B: POST Code LED Decoder
Appendix B: POST Code LED Decoder
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 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.
