Troubleshooting and FAQs

If the OnBoard Ethernet Controller Can’t Connect to the Network

Make Sure the Cable is Installed Properly

The network cable must be securely attached at both RJ-45 connections (controller and hub). The maximum allowable distance from controller to hub is 100 meters. If the cable is attached and the distance is within acceptable limits but the problem persists, try a different cable.

If you’re directly connecting two computers (no hub), use a crossover cable. Most hubs require a straight-through cable, while most switches require a crossover cable (see your hub or switch documentation to verify).

See the Cabling Information readme file for more information on crossover cables.

Check the LED Lights on the Controller

The controller has two diagnostic LEDs above the cable connector. These lights help indicate if there’s a problem with the connector, cable, or switch/ hub. The table on the next page describes the LEDs.
