Troubleshooting
Verify that you are using the right power cord/adapter. The power output of the
adapter can’t be higher than the power rating of the equipment. Otherwise, the
equipment will burn down.
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: 100
Ω
Category 3, 4 or 5
cable for 10Mbps connections, 100
Ω
Category 5 cable for 100Mbps connections,
or 100
Ω
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.
