connections or 100Ω Category 5 cable for 100Mbps connections. Also be sure

that the length of any twisted-pair connection does not exceed 100 meters (328

feet). Gigabit port should use cat-5e or above cable for 1000Mbps connections.

The length does not exceed 100 meters.

Improper Network Topologies

It is important to make sure that users have a valid network topology. Common

topology faults include excessive cable length and too many repeaters (hubs)

between end nodes. In addition, users 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.

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 turn on when the power cord is plugged in, the

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.
