￿Improper Network Topologies

It is important to make sure that you have a valid network topology. Common topology faults include excessive cable length and too many repeaters (hubs) between end nodes. In addition, you should make sure that your network topology contains no data path loops. Between any two ends nodes, there should be only one active cabling path at any time. Data path loops will cause broadcast storms that will severely impact your network performance.

Diagnosing LED Indicators

The Switch can be easily monitored through panel indicators to assist in identifying problems, which describes common problems you may encounter and where you can find possible solutions.

IF the power indicator does turn on when the power cord is plugged in, you may have a problem with power outlet, or power cord. However, if the Switch powers off after running for a while check for loose power connections, power losses or surges at power outlet. IF you still cannot resolve the problem, contact your local dealer for assistance.

Diagnosing POE problems

￿No Power Forward

￿Make sure your PD device comply with IEEE 802.3af standard, the 8 10/100TX plus One Exp. slot unmanaged POE switch only support the IEEE 802.3af compliant PD.

￿The POE switch uses the signal power pair to forward power, the data and the power is traverse the pin. Please, check the documentation for your PD device to
