6. Troubleshooting
• Verify that you are using the right power cord/adapter (DC 48V), please don't use the power adapter with DC
output higher than 48V, or it will burn this converter 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 shield twisted-pair (STP) cable for RJ-45 connections: 100
Ω Category 3,
4 or 5 cables for 10Mbps connections, 100 Ω Category 5 cable for 100Mbps connections 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 unit can be easily monitored through panel indicators to assist in identifying
problems, which describes common problems you may encounter and where you can find possible solutions.
• If the power indicator does not light up 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 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.
