Q. If ExpressBox 3T does not power up how do I determine whether I have a bad
power supply, a bad interface card or defective cable?
A: A working system should illuminate - Five Green LEDs D519, D7000, D701, D24
AND D21 on the interface card, which are located on the top left corner.
• When you have a Bad Power Supply, you won't see any Green LEDs lit at all on
the Interface card.
• When you have a bad cable, you don't see LEDs D701, D24 AND D21 coming
on. Swap or replaced the Thunderbolt Cable.
• If you already swapped the Thunderbolt cable and still LEDs D701, D24 AND
D21 are not coming on this indicates you have a bad interface card.
Q: How can I determine if the driver for my PCIe card is Thunderbolt Compatible?
A: Thunderbolt Tunneling is required for MacOS. In Apple System Profile, click on the
specific PCIe card in question to see if its Thunderbolt Tunnel Compatible. If it shows
“Yes” then Thunderbolt tunneling has been enabled. If it shows “No”, then the driver
does not work through Thunderbolt and the PCIe card will not be visible in ExpressBox
3T.
