Hi Martin,
Gary means to simply look into the port from the outside. There are 8 "wires" - actually Beryllium-Copper "springs" that are held under tension and which slip into the little notches in the RJ45 plug on the end of your patch lead when you plug it in. If some of these wires have been pushed out of position and are touching each other there is a possibility that the POST is detecting the fault.

BTW, while anything is possible, I'd be very surprised if you find a memopry fault based on the lack of report of strange things/unreliability once the machine is up and running.

You're only paranoid if you're wrong!
