Diagnosing LED Indicators:
To assist in identifying problems, the Switch can be
easily monitored through panel indicators, which describe common problems the
user may encounter and where the user can find possible solutions.
If the power indicator does not light on when the power cord is plugged in, user may
have a problem with power cord. Then check for loose power connections, power
losses or surges at power outlet. If you still cannot resolve the problem, contact the
local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected cables are
correct but the packets still cannot transmit. Please check your system’s Ethernet
devices’ configuration or status.
