Verify that is using the right power cord/adapter (DC 24-48V), please
don’t use the
power adapter with DC output higher than 48V, or it may damage this device.

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
