Thunderbolt™ 2 Interface Card & LEDs
There are 10 LEDs on the Thunderbolt™ 2 Interface card. These LEDs are very essential in checking the
power status of the board. It also serves as failure indicators and helps in troubleshooting hardware
problems.

Fully Operational: With monitor attached -LEDS

When the Thunderbolt™ 2 Interface card is fully operational and with an external Display device
attached, 7 solid Green LEDs (D1,D3,D4,D5,D6,D7 and D9) are illuminated. See picture on FIGURE T2-A.
If you do not have an external display attached, only 5 Green LEDs are illuminated. See FIGURE T2-B.
FIGURE T2-A
If the above LEDs are not coming ON, it is an indication that your board is not getting power or the board is

2. Thunderbolt™ 2 Interface card is seated all the way in the PCIe slot. Try reseating the card in the
