I have been using an 8 port Cisco 2960 switch for around 6 months, with no issues. When I received it I connected it up in a similar way to my previous BT switch as shown below. However I saw a picture posted somewhere on this forum that had an Ethernet cable connected into the far right port which I have question marked.
As a result I tried connecting my internet connection to that port, without knowing if this was the correct thing to do, as shown below. All still works with no issues but I wonder which is the correct connection method as I cannot find any guidance on the web. Can anyone help with this?
