Connection 2 PC 6248 10gb SFP+

Hi,

 

We trying to connect 2 switches power connect 6248 using U691D module in bay2 in 2 switches.

We using gbic Ftlx8571d3bcl-fc in 2 switches

When we connect the fiber between two switches with Ethernet in stack-port status of ports is Down

We using last firmware: 3.3.18.1

What could be happening? I using incorrect gbic/transceiver?

I not using to stack, I want to connect different switches via 10gb port.

Below logging of switches, running config and port status:
