Thunderbolt™ 2 Interface Card & LEDs
There are 10 LEDs on the Thunderbolt™ 2 Interface card. These LEDs are essential in checking the power status of
the board. It also serves as functional and 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 don’t have an external display attached, only 5 Green LEDs are illuminated. See FIGURE T2-B.
