This Appendix discusses how to diagnose and fix errors quickly
yourself without having to contact a dealer or Lantronix.
When troubleshooting, always ensure that the physical connections
(power cable and network cable) are secure. If you have trouble
with wireless networking, it may help to connect the MPS to a wired
Ethernet network to verify that it is working properly and to check
the wireless settings.
Note: Some unexplained errors may be caused by duplicate IP
addresses on the network. Make sure that your MPS IP address is
unique.
Power-up Troubleshooting
There are several possible error situations if the LEDs do not flash.
