Troubleshooting and Technical Support

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
