 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 end 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
To assist in identifying problems, the Switch can be easily monitored through panel
indicators, which describe common problems the user may encounter and where the user
can find possible solutions.
IF the power indicator does not light 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.
