Troubleshooting
Verify the switch is using the right power cord/adapter (DC 12-48V), please don’t
use the power adapter with DC voltage higher than 48V, or it may damage the
switch.
Select the proper UTP cable to construct user network. Please check that is using
the right cable. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable
for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10Mbps connections, 100
Category 5 cable for 100Mbps connections, or 100 Category 5e/6 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: The Switch can be easily monitored through panel
indicators, which indicate common problems. Check the switch panel LEDs to
assist in identifying problems.
If the power indicator does not light on when the power cord is plugged in, there
may be a problem with the power cord. Check for loose power connections, power
losses or surges at power outlet. If user still cannot resolve the problem, contact
user local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected cables are
correct but the packets still cannot transmit, Please check configuration or status.
