3.1 Troubleshooting
3.1.1 Power Input
Verify you are using the included or appropriate power cord/adapter. Please don’t
use the power adaptor with DC output voltage higher than power rating of the device.
Otherwise it will burn down.
3.1.2 Cable
Select the proper UTP cable to construct the network. Please check the cable being
used. Prepare 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).
Otherwise, use the 50/125 ~ 62.5µm fiber cable to connect the fiber port in multi-
mode.
3.1.3 Diagnosing LED Indicators
The switch can be easily monitored through LED indicators to assist in identifying
common problems users may encounter and where users can find possible
solutions.
If the power indicator does not light up when the power cord is plugged in, users may
have a problem with power cord. Then check for loose power connections, power
losses or surges at power outlet. If users 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.
