13. Network troubleshooting
Most Ethernet adaptor cards have two LEDs associated with each port. The first indicates that the link is connected
and the second indicates network traffic. Please note that some Macintosh computers do not have external LEDs to
indicate status. Instead the link status is shown in the System Preferences/Network menu.
On your host workstation computer, confirm that the link LED is permanently illuminated. If it is not permanently
illuminated, it suggests you have a cabling error. In this instance please check the following:
• The RJ45 network connector on the console and on your workstation are fully inserted
• If you are using a pin to pin cable to make a direct connection between your console and workstation, try replacing
your cable with an RJ45 crossover cable
• Try replacing the network cable
• If you are not using a direct connection between your console and workstation using the default fixed IP address
on the console, please try this simple configuration to rule out issues with external routers and network switches
• If the link LED is illuminated, the next step is to confirm that the activity LED is illuminating periodically to show
network traffic. If it does not illuminate periodically check the following:
• If your workstation is not connected directly to your console using a crossover RJ45 cable and fixed IP addressing,
follow the installation instructions for a simple network configuration to rule out issues with any external routers
or network switches.
