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.
LED Description
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.
LINK 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.
