 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 monitored through panel indicators, which describes common problems
you may encounter and where you can find possible solutions to assist in identifying
problems.
If the power indicator is not lit when the power cord is plugged in, you may have a problem
with the 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.
