Troubleshooting Checklist
The following checklist may help you diagnose your problem:
•
Verify that you are using the correct types of cables on the correct connectors
and that all cables are connected securely using the hardware documentation.
•
Most customer problems reported to Comtrol Technical Support are
eventually traced to cabling or network problems.
•
Isolate the unit from the network by connecting the device directly to a NIC in
a host system.
•
Verify that the Ethernet hub and any other network devices between the
system and the Comtrol device are powered up and operating.
