Page 21: Configuration Rules With Full Duplex
Configuration Rules with Full Duplex 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). - Page 22 1: I 3300 HAPTER NTRODUCING THE WITCH...
