Improper Network Topologies
It is important to make sure that user have a valid network topology. Common topology
faults include excessive cable length and too many repeaters (hubs) between end
nodes. In addition, user should make sure that 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 network
performance.
5.2 Diagnosing LED Indicators
The switch can be easily monitored through panel indicators to assist in identifying
problems, which describes common problems you may encounter and where user can
find possible solutions.
If the power indicator does turn on when the power cord is plugged in, 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 resolved, contact the local dealer for
assistance.
