Trouble shooting
 Verify that you are using the right power cord/adapter (DC 12 ~ 48V).
Please
don‘t use the power adapter with DC output higher than 48V, or
this switch will be burned 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: 100 Ω Category 3, 4 or 5 cable for 10Mbps
connections, 100Ω 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.
