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.
