LED Description
Link Each port has two LEDs on its connector. The green LED on the left side of
the connector indicates the link status. When this LED is lit, the port
hardware is detecting that a cable is plugged into the port and the port has
established communication with the device at the other end.
Activity The amber LED on the right side of each port connector flashes each time
the port’s transceiver sends or receives packets.
