Diagnosing LED Indicators:
The Switch can be easily monitored through
panel indicators, which describes common problems you may encounter
and where you can find possible solutions, to assist in identifying
problems.
IF the power indicator does not light on when the power cord is plugged in,
you may have a problem with power cord. Then check for loose power

resolve the problem, contact your local dealer for assistance.
If the Industrial switch LED indicators function normal and the connected
cables are correct but the packets still cannot transmit, please check your
