ENET LED Descriptions

The ENET serial hardware uses bicolor LEDs to indicate device and port status. The following table describes these LEDs; the following figure shows their location.

LEDDescription
PWR/RDY Flashes rapidly at start-up while performing self tests and when acquiring network parameters. A steady yellow state indicates the box is ready for operation. Slow flashing pattern indicates an error occurred.
LINKĀ 10/100 Indicates the serial ENET interface detected a twisted pair (10Base-T or 100Base-TX) link. The color indicates the connection speed. If yellow, the speed is 10 Mbits/s. If green, the speed is 100 Mbits/s.
TX Indicates the serial ENET interface is transmitting to the Ethernet network.
RX Indicates the serial ENET interface is receiving Ethernet network traffic.
PORT x Indicates which serial ports are open.
