Troubles shooting
 Verify that you are using the right power cord/adapter (DC 12 - 48V),
please don’t use the power adapter with DC output higher than 48V, or it
will burn this switch down.
 Select the proper UTP/STP cable to construct your network. Please check
that you are using the right cable. Use unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable for RJ-45 connections: 100Ω Category
3, 4 or 5 cable for 10Mbps connections, 100Ω Category 5 cable for
100Mbps, or 100Ω Category 5e/above cable for 1000Mbps connections.
Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).
 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
connections, power losses or surges at power outlet. IF you still cannot
resolve the problem, contact your local dealer for assistance.
 If the Industrial switch LED indicators are normal and the connected
cables are correct and the packets still cannot transmit. Please check your
system’s Ethernet devices’ configuration or status.
