The status LEDs integrated in the RJ45 connector indicate link activity and baudrate. The green LED indicates
baudrate and blinks steadily when the drive is running at the network speed (10/100Mbps). The yellow LED
indicates link activity and flashes when the drive is communicating (transmitting/receiving) with the network.
