XGS1250-12 not linking at 10G or any speed / port

cozman

I have 2 systems (win11) and I am using ASUS XG-C100C NIC. Neither NIC will establish link with the switch. I have tried auto negotiate, forcing both sides the 10G. No success. If I set the card to auto and plug into a 1G port, same results. NIC supports 1,2.5,5,10G. I have tried several cables Cat6, 7' long. If I use the same cable and plug NIC into a netgear switch, it immediately links at 1G and passes traffic. I upgraded my switch firmware to v2.00(ABWE.1)C0, no change. I have verified I have the latest driver from ASUS for the NIC. Any suggestions?

Hi @cozman,

Could you help provide some clarification?

1. Please help to check if the switch front panel has an LED ECO mode button. If so, please help to press it for 5 seconds and then release. LED ECO mode will change the link LED to be disabled when the link status is up.
2. Please help to connect a loop on the switch. If neither the ports can't link up, this could be a device hardware issue. In addition, the XGS1250-12 enable loop prevention by default, therefore, you will find only one port's link LED keeps on in the loop test.
