Trouble shooting
Verify you have the right power cord or adapter. Never use a power supply or adapter with a non-
compliant DC output voltage or it will burn the equipment.
Select the proper UTP or STP cable in order to construct the network. Use an unshielded twisted-pair
(UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100
Ω
Category 5e for
10M/100/1000Mbps. Also be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
Diagnosing LED Indicators: To assist in identifying problems, the switch can be easily monitored with
the LED indicators which help to identity if any problems exist.
Please refer to the LED Indicators section for LED light indication.
If the power indicator LED does not turn on when the power cord is plugged in, the user may have a
problem with the power cord. Check for loose power connections, power losses or surges at the power
outlet.
If the industrial switch LED indicators are normal and the connected cables are correct but the packets
still cannot transmit, please check the systems Ethernet devices configuration or status.
