General Purpose LEDs

The CP6003-SA provides four General Purpose LEDs (LED0..3) on the front panel. They are
designed to indicate the boot-up POST code after which they are available to the application.
If the LED0..3 are lit red during boot-up, a failure is indicated before the uEFI BIOS has started.
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 Gen-
eral Purpose or Port 80 signals, depending on the uEFI BIOS settings. The default setting after
boot-up is General Purpose.
