Chapter 4 Troubleshooting

Verify that you are using the right power cord/adapter (+12 ~ 48VDC), please don’t use the power adaptor with DC output voltage higher than 48 V, or it will burn this converter down.

Select the proper UTP cable to construct the user network. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10Mbps connections, 100 Category 5 cable for 100Mbps connections, or

100Category 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 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, 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 the local dealer for assistance.

If the LED indicators are normal and the connected cables are correct but the packets still cannot be transmitted. Please check the user system’s Ethernet devices’ configuration or status.
