6. 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: 100Ω
Category 5e for 10M/100Mbps. 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.
o
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.
o
Please contact Antaira for technical support service, if the problem still
cannot be resolved.
If the industrial switch LED indicators are normal and the connected cables are correct but
the packets still cannot transmit, please check the system’s Ethernet devices’ configuration
or status.
