Troubleshooting
7 TROUBLESHOOTING
7.1 POWER INPUT
Verify that is using the right power cord/adapter (+12~48 VDC), please don't use the power
adaptor with DC output voltage higher than 48 V, or it will burn this converter down.
7.2 CABLE
Select the proper UTP cable to construct user network. Please check that is using the right
cable. Use Unshielded Twisted-Pair (UTP) or Shielded Twisted-Pair (STP) cable for RJ-45
connections: 100 Category 3, 4 or 5 cable for 10 Mbps connections or 100 Category 5 cable
for 100 Mbps connections. Also, be sure that the length of any twisted-pair connection does
not exceed 100 meters (328 feet).
7.3 DIAGNOSING LED INDICATORS
The switch can be easily monitored through panel indicators, which describes common problems
user may encounter and where user can find possible solutions, to assist in identifying. If the
power indicator does not light up when the power cord is plugged in, user may have a problem
with power cord. Then check for loose power connections, power losses or surges at power
outlet. If user still cannot resolve the problem, contact the 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 your system's Ethernet devices configuration or status.
