LED color LED name Description (when LED is ON)
D21 Red PORST The CPLD is asserting PORESET_B to the processor and
is in the process of restarting the system
D22 Red RST REQ The processor is asserting RESET_REQ_B. This is
typically due to the reasons described for the ASLEEP
LED.
D23 Red THERM
Thermal monitors have detected a thermal fault and have
shut down the system
Unless reprogrammed by user
software, the thermal trip point is 85
°C.
NOTE
D41 Red ROTERR The processor has been installed in the socket rotated 90,
180, or 270 degrees from the pin 1 orientation. The
system and device power supplies have been shut down
to protect the device.
D24 Green M7 General status. See Multi-status LEDs for details.
D25 Green M6
D26 Green M5
D27 Green M4
D42 Green M3
D43 Green M2
D45 Green M1
D44 Green M0
D28 Green 3VSB The ATX power supply is supplying 3.3 V “standby power”
to the system. The system cannot power up unless this
supply is provided.
D29 Green 3V3 3V3 ATX power supply is operating correctly
D30 Green VDD VDD (processor core) power supply is operating correctly
D31 Green GVDD GVDD (DDR4) power supply is operating correctly
D32 Green SDAV SD_AVDD power supply is operating correctly
D33 Green USBV USB_SVDD power supply is operating correctly
D34 Green OVDD OVDD power supply is operating correctly
D35 Green 0V85 0V85 power supply is operating correctly
D36 Green VTT1 VTT1 power supply is operating correctly
D37 Green SDV SD_VDD power supply is operating correctly
