Lantronix ETS8PS, ETS16PS, ETS32PR, ETS16PR manual Power-up Troubleshooting

B: Troubleshooting

This appendix discusses how to diagnose and fix errors quickly yourself without having to contact a dealer or Lantronix. It will help to connect a terminal to the serial port while diagnosing an error to view any summary messages that are displayed.

When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure.

Note: Some unexplained errors may be caused by duplicate IP addresses on the network. Make sure that your ETS IP address is unique.
