XSM4348FS stack -link shows as offline

Hi,

I have a stack of two XSM4348FS-100NES, I configured ports 45,46, and 47 as stack ports. 

The link is not showing when I am connecting port 45 of both switches using  SFP AGM732F-R and 2 meter SM patch cord. port 47 I am connecting using cat 6 cables, which is coming up .Do I need to use a DAC cable or any other issue?
