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, which 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 power
outlet. IF you still cannot resolve the problem, contact your local dealer for assistance.
„ Cabling
RJ-45 ports: use unshielded twisted-pair (UTP) or shield twisted-pair ( STP ) cable for
RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps 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-5 or cat-5e cable for 1000Mbps connections. The length does not exceed 100
meters.
