SFP+ connection ist not working

Hello,

I am a beginner and I need some help.

I have the follwoing devices:

CRS112-8P-4S
CRS326-24G-2S+

I bought a Mikrotik SFP Cable (XS+DA0001 - SFP/SFP+/SFP28 1/10/25G) and connected both devices.

The cable is not recognized. The LEDs are not green. In Winbox the Module Present is inactive?

Do I need to activate something?

Thanks for your help
