6. Light Guided Diagnostics
The Intel® Visual Compute Accelerator Board includes several LEDs to indicate the health of the card.
6.1 Power LEDs
Two LEDs located on the back edge of the card, and visible externally from the back of the system, are used
to indicate the status of power to the board. One AMBER LED to indicate the status of 3.3V auxiliary power
and one GREEN LED to indicate the status of 3.3V main power. Each LED should be illuminated when power
is present.

6.2 Processor CATERR LEDs
Three LEDs on the back side of the board (viewable when the system is open) are used to indicate when a
CATERR for a specific CPU has occurred. When a CATERR on a specific CPU is detected, the given LED will
illuminate RED. In a normal state, these LEDs are not illuminated.
