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.

Problem/Message Error Remedy
The ETS is connected to
a power source, but there
is no LED activity.
The unit or its power supply
is damaged.
Contact your dealer or Lantronix
Technical Support for a
replacement.
The ETS is unable to
complete power-up
diagnostics.
This generally indicates a
hardware fault. One of the
LEDs will be solid red for
three seconds, followed by
one second of another
color.
Note the blinking LED and its color,
then contact your dealer or
Lantronix Technical Support. The
ETS will not be operational until the
fault is fixed.
The ETS completes its
power-up and boot
procedures, but there’s
no noticeable serial
activity.
There is a problem with the
serial connection or the set-
up of the serial device.
Check the terminal setup and the
physical connections, including the
cable pinouts (see C:Pinouts). Try
another serial device or cable, or
cycle power on the ETS.
