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 or 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.
Diagnostic LED Indicators
The Switch can be easily monitored through panel indicators to assist in
identifying problems.
If the power indicator does not 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.
