Note: no matter the Gigabit LAN card contains Link signal or not, the ACTLED on
the left always indicates the data transmission status. When data is being transmitted,
the green LED on the left is “flashing”; when it is connected to network with no data
transmission, the green LED is “off”; when there are broadcasting packages, it is
normal if the ACTLED is “flashing”.
