Troubleshooting
Verify that the device is using the right power cord/adapter (DC 48V); please
don't use a power adapter with DC output higher than 48V, or it may damage
this device.
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 that
depend on the connector type the device equipped: 100R Category 3, 4 or 5
cable for 10Mbps connections, 100R Category 5 cable for 100Mbps connec-
tions, or 100R Category 5e/above cable for 1000Mbps connections. Also ensure
that the length of any twisted-pair connection does not exceed 100 meters (328
feet).
R = replacement letter for Ohm symbol.
Diagnosing LED Indicators:
To assist in identifying problems, the device 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; check for loose power connections, power
losses, or surges, at the power outlet. If you still cannot resolve the problem,
contact a 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.
