NIC not rcognized

I build a NAS box based on Supermicro X11SSM-F. This board has rwo onboard NICs. These NICs are recongnised perfectly. later I inserted a new 10GBase-T NIC (Intel X550-T1) but this NIC isn’t available.
I can’t find the NIC wehter in the GUI nor with ifconfig on the command line.

Any ideas how to solve thos issue?

Hello Uwe,

Not immediately, but it could be a driver issue. Could you check the following things:

  • Output of lspci to see whether the card is listed;
  • Output of lsmod | grep ixgbe to see whether the driver has been loaded (probably not);
  • Logs: journalctl -xb and look for any messages about the ethernet devices.
