4.1 Troubleshooting

Verify that you are using the right power cord/adapter. Please don't use a power
adapter with DC outputs higher than the power rating of this equipment, or it will
be damaged.
 Select the proper UTP/STP cable for your network. Please check that you are
using the right cable. Use unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable for the RJ-45 connections: 100
Ω Category 3, 4, or 5 cable for
10Mbps connections or 100 Ω Category 5 cable for 100Mbps connections. Also
be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
 Diagnosing LED Indicators: The device can be easily monitored through LED
indicators, which describe common problems the user may encounter and
where the user can find possible solutions.
 If the power indicator does not light up 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 the power outlet. If you still cannot resolve the prob-
lem, contact your local dealer for assistance.
 If the cables are properly connected and the LED indicators show normal, but
the packets still cannot transmit, please check your system's Ethernet devices'
configuration or status.
