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.
