Debug LEDs

The CP6003-RA/RC provides four onboard Debug LEDs (DLED0..3) located on the rear side
of the board. They indicate the boot-up POST code after which they are available to the appli-
cation.
If the DLED0..3 are lit red during boot-up, a failure is indicated before the uEFI BIOS has start-
ed. In this case, check the power supply. If the power supply appears to be functional and the
LEDs are still red, please contact Kontron for further assistance.
The POST code is indicated during the boot-up phase. After boot-up, the LEDs indicate Debug
or Port 80 signals, depending on the uEFI BIOS settings. The default setting after boot-up is
Debug.
