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 cable to construct your network. Please check that
you are using the right cable. Use unshielded twisted-pair (UTP) or shield
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.
