I wanted to use this module on my UDM Pro to use port 10 to connect to my WAN2 via an LTE module.
I have assigned port 10 to WAN2 as failover, but it does not establish a connection. Even the link arrow under the port that lights up normally remains completely off (normally something moves, only when a module is plugged in). I have also tried auto negotitation and 1Gbps FDX.

If I plug the whole thing directly into RJ45 port 8 as the assigned WAN2, it works.

What could be the problem? Or what am I doing wrong?

Answer

That module is only compatible with a 1 gb connection. I had the same problem. I solved it by putting a small gigabit switch between the sfp module and the wan.
