Configuration Rules with Full Duplex

21

The key topology rules are:

■Maximum UTP cable length is 100m (328ft) over Category 5 cable.

■A 412m (1352ft) fiber run is allowed for connecting switch-to-switch, or endstation-to-switch, using half-duplex 100BASE-FX.

■A total network span of 325m (1066ft) is allowed in single-repeater topologies (one hub stack per wiring closet with a fiber run to the collapsed backbone); for example, a 225m (738ft) fiber link from a repeater to a router or switch, plus a 100m (328ft) UTP link from a repeater out to the endstations.

Configuration Rules The Switch provides full duplex support for all its fixed ports, including

with Full Duplex Expansion Module ports. Full duplex allows packets to be transmitted and received simultaneously and, in effect, doubles the potential throughput of a link.

With full duplex, the Ethernet topology rules are the same, but the Fast

Ethernet rules are:

■Maximum UTP cable length is 100m (328ft) over Category 5 cable.

■A 2km (6562ft) fiber link is allowed for connecting switch-to-switch, or endstation-to-switch.
