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 LED goes 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
