I have a dev board with a RJ45 connector which has magnetics integrated. I need put it into a case and mount another RJ45 on the panel, sadly I have only another connector which also integrate the magnetics. If I can use a cable simply connect the RX-, RX+, TX-, TX+, of my board connector to the RD-, RD+, TD-, TD+ pins of the connector on the front panel, but left the CT pins open?
I've tried that, and it works, at least. But more explanations are welcome here. And is it a good or bad design?
