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.
