Troubles shooting

•Verify that is using the right power cord/adapter (DC 24-48V), please don’t use the power adapter with DC output higher than 48V, or it may damage this device.

•Select the proper UTP/STP cable to construct the user network. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections that depend on the connector type the switch equipped: 100Ω Category 3, 4 or 5 cable for 10Mbps connections, 100Ω 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: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.
