DANGER
To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector.
You can only connect an Ethernet cable to this connector.
The Ethernet connector has two indicators that show the status of the network connection. When the top-left
indicator is solid green, it indicates that the computer connects to a LAN and a session with the network is
available. When the top-right indicator blinks yellow, it indicates that data is being transmitted.
Note: If you attach the computer to a supported docking station, use the Ethernet connector on the docking
station to connect to a LAN, not the one on the computer.
