I'm looking at getting an ASUS 15.6" Slimline Notebook F502CA-XX081H. It's the model without the optical drive as I want something a bit lighter to take to tech with me and not lug around a heavier laptop, but I can't identify one of the ports correctly.
In all the descriptions I've found it's just called a "network port", is this a RJ-45 port? I haven't seen one quite like this before.
Please see the photo and the red arrow :)

Thanks.
