FIGURE C
If there is no Display Monitor attached to Thunderbolt™ 2 Interface card it would only show FIVE illuminated GREEN
LEDs, which is normal. If you have a Display Monitor attached, LEDs D1 and D5 should come on. Otherwise, the
Thunderbolt™ 2 Interface card is not properly working or the monitor Displayport cable is faulty.
