The LED indicators on the right-top (for the upper LAN connector) and right-bottom (for the
lower LAN connector) corners glow a solid green color when the cable is properly connected
to a 100 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are
being transmitted or received.
The LED indicators on the left-top and left-bottom corners glow a solid yellow color when the
cable is properly connected to a 1000 Mbps Ethernet network. The LED will flash on and off
