B - Troubleshooting
This Appendix discusses how to diagnose and Þx 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 will be displayed.
NOTE:
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 MSS IP address 
is unique.

The MSS 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 MSS is unable to 
complete power-up 
diagnostics.
 This generally indicates a 
hardware fault. Either the 
OK or Serial LED 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 
MSS will not be operational until 
the fault is Þxed.
