Brand new XGS1250-12. Seems it may be dropping 10G port randomly

The switch is on a shelf so plenty of circulating air and ambient is ~70 fahrenheit.

So far I've had it for about 3 days and had 3 drops. It's connected to my router (running opnsense with a Chelsio T540-BT) which had been working fine by itself as a software switch for months. I see the NIC card that connects from OpnSense←→switch 10G port go offline when this happens, the led on the card itself goes red. The addition of the XGS is the only change to this set up. Thanks.

This would be Ethernet port not SFP+ ?

Have you got the newest firmware?

Maybe your setup before was fine due to transmission voltage working well with the cable you have but XGS1250-12 has a lower transmission voltage that your cable is no good now?

Look to get a CAT6 or CAT6a that are Shielded like

Yes this is the regular RJ45 10GBE Port that is being used.

The switch came with the latest firmware as far as I can tell.

I am expecting to receive an Intel X520-DA2 card soon and a DAC cable as well so I am going to test that set up as well. My cables are these:

p.s. AI said to set the port on the NIC to 10G full duplex instead of 'auto' because if the switch has any drops the NIC won't try to renegotiate. So far it has been good.
