If the above LEDs are not coming ON, it is an indication that your board is not getting power or the board is faulty or
defective. Please check the Standby-power cable is firmly connected to Thunderbolt™ 2 Interface card power connector (J7).
Make sure the Thunderbolt™ 2 Interface card is seated all the way in the PCIe slot. Try reseating the card in the PCIE slot.
If you reconnected an external Display device, LEDs D1 and D5 should come on immediately. Otherwise, the Thunderbolt™ 2
Interface card is not properly working or the monitor Display port cable is faulty.
