Troubleshooting
Verify that is using the right power cord/adapter (DC 12-48V), 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: 100R Category 3, 4 or 5
cable for 10Mbps connections, 100R Category 5 cable for 100Mbps
connections, or 100R 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).
R = replacement letter for Ohm symbol.
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.
