Issue enabling 10 Gig SFP+ with 40G Module Adapter in X590

[HarrySo]

I have a problem with getting a 10G SFP+ Adapter online. The SFP+ is plugged in a 40Gig Adapter. When i check the port in CLI Mode everything seems ok, but i can t get a link to the other switch.

This occurs only in the X590 port 25-28, it works fine with the X690 or X870

Thank you very much Stephen, I did not expect that there would be a hardware limitation
