Cant get the 10 Gig ports on the Cisco 4506 Sup 7E Card

I am trying to connect a couple 4506 Switches with Sup 7E Cards by their 10 Gig ports with SFP+ modules

So far by connecting them and just doing switchport mode trunk and a no shut on the two interfaces but the interfaces do not come up.

Am I missing some command in order to enable 10Gigabit on them?

​

Cheers,

Chris
