￿Improper Network Topologies

It is important to make sure that the network topology is valid. Common topology faults include excessive cable length and too many repeaters (hubs) between end nodes. In addition, the user should make sure that the 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 the network performance.

Diagnosing LED Indicators

To assist in identifying problems, the switch 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 turn on when the power cord is plugged in, the user 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 the problem still cannot be solved, please contact the local dealer for assistance.

Diagnosing PoE problems

￿No Power Forward

￿Make sure the connected PD device complies with IEEE 802.3af standard. The PoE switch only supports the IEEE 802.3af compliant PD.

￿The PoE switch uses the signal power pair to forward power, the data and the power traverse the pin. Please check the documentation for your PD device to make sure the power pair it uses. The following table is the signal power pair RJ-45 port pin out:
