Hi Austin. Is *enx70886b87f283 *a 1 gigE or 10gigE connection? If it's 1gigE, my guess is that your problem may be that the new SD card is loading the XG FPGA image, which expects 10 gigE connections to the host on both ports SFP0 and SFP1. You'll need to update the SD card to load the HG image from /lib/firmware at bootup (1 gigE on SFP0 on the N310, connected to the Host PC using a cat 5 Ethernet cable and the SFP-to-RJ45 adapter).
