10: Troubleshooting
This chapter discusses how you can diagnose and fix errors quickly without having to
contact a dealer or Lantronix. The WiPort NR diagnostic LEDs indicate the unit’s
status. It helps to connect a terminal to the serial port while diagnosing an error to
view summary messages that may be displayed. When troubleshooting, always
ensure that the physical connections (power cable, network cable, and serial cable)
are secure.
Note:
Some unexplained errors might be caused by duplicate IP addresses on the
network. Make sure that your unit's IP address is unique.
When troubleshooting the following problems, make sure that the WiPort NR
embedded device server is powered up. Confirm that you are using a good network
connection.
