Chapter 4: Troubleshooting
4.2 Additional Troubleshooting Suggestions
If the suggestions in Section 4-1 do not resolve your problem, refer to the troubleshooting suggestions in this section.
4.2.1 Configuration
If problems occur after altering the Industrial Ethernet Extender’s network configuration, restore the original connections and determine the problem by implementing the new changes one step at a time. Be sure cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations.
4.2.2 Industrial Ethernet Extender Integrity
If required, verify the integrity of the Industrial Ethernet Extender by resetting it.
4.2.3 Auto-Negotiation
The 10/100 Mbps ports negotiate the correct duplex mode and speed since the Industrial Ethernet Extender is configured for auto-negotiation (this is the Industrial Ethernet Extender’s default setting) and the device at the other end of the link supports auto-negotiation. If the device does not support auto-negotiation, the Industrial Ethernet Extender determines only the speed correctly and the duplex mode defaults to half-duplex.
