Troubleshooting
 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 converter 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: To assist in identifying problems, the
industrial switch converter 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,
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 converter 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.
