Troubles shooting
Verify that you are using the right power cord/adapter (DC 12 ~ 48V). Don’t use a power
adapter with DC output higher than 48V, or it may damage the switch.
Select the proper UTP cable to construct your network. Please check that you are using
the right cable. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for
RJ-45 connections: 100Ω Category 3, 4, or 5 cable for 10Mbps connections, 100Ω
Category 5 cable for 100Mbps, 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: the Switch can be easily monitored through panel
indicators, which describes common problems you may encounter and where you can
find possible solutions, to assist in identifying problems.
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 your local dealer
for assistance.
If the Industrial Switch LED indicators are normal while the connected cables are correct,
but the packets still cannot transmit. Please check your system’s Ethernet devices’
configuration or status.
