This section describes the cabling guidelines and port connections.
For copper Ethernet ports, cable lengths from the switch to connected devices
must be within 328 feet (100 meters).
Use either straight-through or crossover Category 5 cables with RJ-45 connectors
to connect from the switch Ethernet ports to other devices.
Use Category 5 cables for 100BASE-TX and 1000BASE-T traffic. Use
Category 3 or Category 4 cables for 10BASE-T traffic.
For the SFP module port connections,
Each port must match the wave-length specifications on the other end of the cable,
and for reliable communications, the cable must not exceed the stipulated cable
length.
Table A-2 lists the cable specifications.
