On the Ethernet connector inside the DTR there are two diagnostic LEDs.
- The green LED indicates that the physical connection is working. Both ends of the Ethernet cable are plugged in, the device in each end is powered and the cable is of correct type.
- The orange LED indicates traffic in the cable, DTR receives data.
You can test the IP address with a ping command after you have set up the physical Ethernet connection and the DTR is powered. To use ping:
- Go to the command interface (for example, Command Prompt in Windows).
- Type ping and the IP address you want to check.
- Press ENTER.
If the Ethernet connection is good, the DTR is powered on, and the address is correct, the DTR answers to ping and returns any data packets sent to it. If DTR returns and error message, see Troubleshooting connection.
