connector is connected to RJ45 magnetic connector (top), with LED indicators. RJ45 Ethernet
connector is physically located on top of the board. Similarly USB HOST0 & USB HOST2
interfaces from MXM connector are connected to bottom and middle port respectively. GBE
connector will work for both 10/100 & 10/100/1000 Mbps Ethernet operation.
