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.
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 dont have an external display attached, only 5 Green LEDs are illuminated. See FIGURE T2-B.

If the above LEDs are not coming ON, it is an indication that your board is not getting power or the board is faulty
