■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 a different cable.
■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 ( 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. The list below 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 the power outlet. If you still cannot resolve the problem, contact your local dealer for assistance.
