11: Troubleshooting and Contact Information

This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. It helps to connect a terminal to the serial port while diagnosing an error to view summary messages that may display. 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 UDS1100 is powered up. Confirm that you are using a good network connection.

LEDs

The UDS has the following LEDs, which help you diagnose problems.

Power LED (green)

Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb)

Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex)

Diagnostic (red)

Status (green)

Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status LED blinks between its pauses. The following table explains the LED functions:
