3.2.2 BMC Status LED and WDT LED
3.2.2.1 Status LED (Blue)
The Status LED is controlled by SEMA to signal system state
changes and power up failures. The system state changes can be
HW-Reset, SW-Reset, Power-Up, Power-Down, Reset-Button and
Power-Button activity. The Status LED will light for short time.
Power-Up failures can indicate a corrupted BIOS or failure of the
onboard power supply. A blink code displays in cases of failure.
When the system is in an S3 state, the Status LED flashes every
four seconds.
3.2.2.2 WDT LED (Red)
The WDT LED is driven by SEMA and will light when a watchdog
timeout occurs. It stays on until it is cleared by software or the
reset button.
