Help

I have a new build home and there are ethernet ports all over the house. The broadband is in the downstairs livingroom which is wired in from the box shown in the first photo

But the ethernet ports throughout the house do not work.... in the closet upstairs there is a bunch of wires handing down but with no connections on the end of them shown in the second photo

Can anyone detail what I need to do to get the ethernet ports up and running?
