Troubles shooting
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.
Select the proper UTP/STP cable to construct the user network. Use unshielded
twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ45 connections that depend
on the connector type the switch equipped: 100Ω Category 3, 4 or 5 cable for 10Mbps
connections, 100Ω Category 5 cable for 100Mbps connections, or 100Ω 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.
