Troubleshooting
If you are having problems, you may want to check the following:
•
Make sure you are using the correct DC power supplies (12 to 48VDC). Do not use power supplies with DC output over
48VDC.
• Select Ethernet cables with specifications suitable for your applications to set up your systems.
Ethernet cables are categorized into unshielded twisted-pair (UTP) and shielded twisted-pair (STP) cables.
Category 3, 4, 5, and 6 Ethernet cables are suitable for systems with 10 Mbps transmission speed.
For systems with 100 Mbps transmission speed, Category 5 and 6 Ethernet cables are the only suitable specifications for
this environment.
You also need to make sure that the distance between any two nodes does not exceed 100 meters (328 feet).
• If the
Power
LEDs go off when the power cord is plugged in, a power failure might have occurred. Check the power
output connection to see if there is any error at the power source. If you still cannot solve the problem, contact Comtrol
Technical Support for assistance.
