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. |
