Connecting the Switch Block

For FastEthernet, the specifications for each type are as follows:

100BaseTX Category 5 UTP wiring; category 6 and 7 is now available.
Category 6 is sometimes referred to as cat 5 plus. Two-pair wiring.
100 meters.

100BaseT4 Four-pair wiring, using UTP category 3, 4, or 5. 100 meters.

100BaseFX Multi-Mode Fiber (MMF) with 62.5-micron fiber-optic
core with a 125-micron outer cladding (62.5/125). 400 meters.

For Gigabit Ethernet, the specifications for each type are as follows:

1000BaseCX Copper shielded twisted-pair, 25 meters.

1000BaseT Copper category 5, four-pair wiring, UTP 100 meters.

1000BaseSX MMF using 62.5 and 50-micron core, uses a 780-
nanometer laser, up to 260 meters.

1000BaseLX Single-mode fiber that uses a 9-micron core, 1300-
nanometer laser. From 3 km up to 10 km.

We showed you how to configure both a set-based switch and a

command-line interface (CLI) switch. And we showed you how to set host-
names and passwords. Finally, you learned how to configure an IP address
on each switch and how to verify the configuration.
