When you connect the 1x40G cable to the N3000. what is the output of fpgainfo phy? UP or DOWN?

    Port0 10G : Up : Up : Down

    Port1 10G : Down : Up : Down

    Port2 10G : Down : Up : Down

    Port4 10G : Down : Down : Down

    Port5 10G : Up : Up : Up

      Hi @fzhan51​ , When you say 1x40G, it is only 1 port at 40G, right?

      Or, Do you mean 4x10G instead? Because the the card can only support 10G per port.

      1 port at 40G --> it makes sense it will FAIL because the card supports 10G per port

      4 port at 10G each --> it makes sense it will PASS because the card supports 10G per port

      Im not sure there is such cable as 1 port at 10G --> then this will further confirm my explanation.

      Btw, 1x40G is NOT EQUAL to 4x10G !!
