Planning Your Network Layout
Building a Fast Ethernet network involves more topology rules in addition to the 10BaseT network rules. These rules specify distance limitations and cabling specifications. Data loss, collisions, and other network problems causing down time are likely to occur if the rules below are not followed.
•Use Category 5 UTP (EIA 568, Cat 5) ethernet cabling with four pairs of wires and
•Use the chart below to position your switches, hubs and workstations.
From | To | Maximum Distance |
Switch | Switch or Hub* | 100 meters (328 feet) 1 |

Hub* | Hub* | 5 meters (16.4 feet) 1 |

*Hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10mbps hub connected to another 10mbps hub can span up to 100 meters (328 feet).
•No more than two hubs should be uplinked in a row in a Fast Ethernet net- work. A set of stacked hubs, which must be stacked with a stacking cable, counts as one hub or node on the network.
•In Fast Ethernet networks, your 10/100 Switch acts as a repeater, regenerat- ing data signals before passing them on to the next device. Hubs do not func- tion as repeaters.
EtherFast 10/100 Autosensing Switches
Configuration A shows one possible way to set up an EtherFast Switch in a Fast Ethernet environment. Note that the Switch requires Category 5 UTP network cabling for all its connections, like all Fast Ethernet network hard- ware.
All of the workstations below can access all resources on the network - 10Mbps users can access the 100Mbps nodes, and vice versa. While allowing the 10Mbps and 100Mbps segments to communicate, the Switch optimizes data traffic by switching the data packets to their destination through the quickest route possible, which improves performance up to 80% even on the faster 100Mbps network segment.
