Troubles 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 56V, 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: 100Ω
Category 3, 4 or 5 cable for 10Mbps connections, 100Ω Category 5 cable for
100Mbps connections, or 100 Ω
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.
