Diagnostic LED Indicators
The switch can be easily monitored through panel indicators to assist in
identifying problems.
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 awhile, 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 shielded 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. Be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).
100BASE-FX and 1000BASE-X Fiber port: Multi-mode fiber connector
types must use 50/125 or 62.5/125 µm multi-mode fiber cable. Two
devices may be connected over a 2 kilometer distance. Single-mode
fiber connector types must use 9/125 µm single mode fiber cable. Two
devices may be connected over a15 to 60 kilometer distance in full
duplex operation in single mode.
1000Base-TX ports use all 8 wires for communication and requireCat-5
or better cable quality.
