Mesa 7i76e wiring

Yes, move the jumper down and then power cycle

If the red light does not go out there may be something broken with the card or you still have power supply issues

I have tried with jumper w9 down but nothing is changed, exattly the same scenario, the leds on the Eth port are NOT lighting.
I have tried using another Linux distribution also (Ubuntu LTS and Stretch), with no luck.
I see always CR1 and CR2 lights so probably the last thing that I must to test is to use another 5V supply. I'm going to buy anotherone and retry, I will let you know.

Thank you all guys.
I nave bought a new 5v supply with much Ah then the previous one and finally the ethernet and connettivity goes up successfully.
To have linuxcnc working i have had to switch on strech preemt RT kernel also and all till now seems be working as expected.
