Hey there, do you also have a 10Gb ethernet capable switch? Or at least another 10Gb ethernet NIC for another computer?
The drivers for this network card are likely not installed by default. From some googling, it sounds like this NIC uses the AQC107 chip, which another user was asking about:
There are lots of posts about solid performance with this NIC in both Core and Scale, so people have definitely gotten it to work in the past. You would likely need to manually install the driver
