7. Troubleshooting
This section is intended to help you solve some common problems encountered while using the
Incorrect connections
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If that does not correct the problem, try different cables.
Non-standard cables
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 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 awhile, 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.
