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.
Note:Most customer problems reported to Comtrol Technical Support
are eventually traced to cabling or network problems.
•
Verify that the network IP address, subnet mask, and gateway is correct and
appropriate for the network. Make sure that the IP address programmed into
the DeviceMaster UP matches the unique reserved IP configured address
assigned by the system administrator.
-
If IP addressing is being used, the system should be able to ping the
DeviceMaster UP.
-
If using DHCP, the host system needs to provide the subnet mask and
gateway.
•
Verify that the Ethernet hub and any other network devices between the
system and the DeviceMaster UP are powered up and operating.
•
Reboot the system, then reset the power on the DeviceMaster UP and watch
the Status (Page 53) light activity.
•
If you have a spare DeviceMaster UP, try replacing the device.
