Q: How can I determine if the driver for my PCIe card is Thunderbolt Compatible?
A: Thunderbolt Tunneling is required for Mac OS. In Apple System Profile, click on the specific PCIe card in question to see if it’s
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.
Q. My PCIe card is not getting detected when installed in 1st PCIE slot, what should I do?
A. You have to configure the DIP Switch (SW1) on the backplane, setting it to proper configuration to match the PCIE card specs.
This troubleshooting is only applicable to Rev A5.1 backplane. The main function of this DIP Switch is as follows
- To set the 1st PCIe slot to train to either GEN1 or GEN2
-
To allow a x8 or x16 PCIE card to run under x4 slot
