Configuration Rules with Full Duplex 21
The key topology rules are:
■Maximum UTP cable length is 100m (328f t) over Category 5 cable.
■A 412m (1352ft) fiber run is allowed for connecting switch-to-switch,
or endstation-to-switch, using half-duplex 100BA SE-FX.
■A total network span of 325m (1066ft) is allow ed in single-repeater
topologies (one hub stack per wiring closet with a fiber run to the
collapsed backbone). For example, a 225 m (7 38ft) fiber link from a
repeater to a router or switch, plus a 100m (328ft) U TP link from a
repeater out to the endstations.
Configuration Rules with Full Duplex The Switch provides full duplex support for all its ports. Full duplex all ows
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 (328f t) over Category 5 cable.
■A 2km (6562ft) fiber link is allowed for connect ing switch-to-switch,
or endstation-to-switch.
