On the each Ethernet port there are two LEDs that indicate the status of the port's Ethernet connection.
Green Link LED (LNK):
The green LED indicates there is a valid Ethernet connection. This
LED will show that the physical Ethernet layer (the cable) is connected. This LED
will also blink to show both transmit and receive activity across the connection.
Orange LED (SPD) :
The orange LED indicates the speed of the Ethernet connection. It will be
illuminated for a 100bT connection, and will be off for a 10bT connection.
