Troubleshooting
Verify that is using the included or appropriate power cord/adapter. Don’t use the
power adaptor with DC output voltage higher than the power rating of the device.
Otherwise, the device will burn down.
Select the proper UTP cable to construct the 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, 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’s Ethernet devices’
configuration or status.
