I have just had full fibre broadband installed and have cable running from the CSP box to the new hub but this has not been connected and just been left loose.Can't be right even though the broadband is working.There are three available ports at the back of the hub.Which one should I plug the cable into ?

Don't want to just take a chance in case I create a problem

There should only be one cable between an ONT and a Hub: it's ethernet and goes to the WAN port.

The CSP is the passive enclosure on the outside of the property.
