Solution
This issue can be caused if you are using a non-Thunderbolt port with the Thunderbolt connection. To fix this, you need to connect your PXIe-8301 to a native Thunderbolt port. Most Thunderbolt ports are identified by a thunderbolt symbol next to the port, as shown in the image below. The most accurate way to tell if a port on your machine is a Thunderbolt connection is to reference its user manual or specification sheet.
