Verify that the right power cord/adapter (DC 12-48V) is being used; please do not use a power adapter with
a DC output higher than 48V, or the device may be damaged.
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.
Also be sure that the length of any twisted-pair connection does not exceed 100 m (328 ft).
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, so the user can be guided
towards 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. Check for loose power connections, power losses or surges, at the power outlet. If you still
cannot resolve the problem, contact a local dealer for assistance.
If the LED indicators are normal and the connected cables are correct but the packets still cannot be trans-
mitted, please check the user system's Ethernet device configuration or status.
