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 10/100/1000Mbps. 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.
◆
Please contact Leonton 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.
