Planning Your Network
Building a Fast Ethernet network involves a few more topology rules in addi- tion to 10BaseT network rules. These rules specify distance limitations and cabling specifications. Data loss, collisions, and other network problems caus- ing down time are likely to result if the rules below are not followed.
•Use UTP Category 5 (EIA 568B, Cat 5) ethernet cabling with four twisted- pair wires and
•Use the chart below to position any switches, hubs and workstations.
From | To | Maximum Distance |
|
|
|
Switch | Switch or Hub* | 100 meters (328 feet) |
Hub* | Hub* | 5 meters (16.4 feet) |
Switch or Hub* | Workstation | 100 meters (328 feet) |

*Hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10Mbps hub linked to another 10Mbps hub or a 10/100 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, an Ethernet Switch acts as a repeater, regenerating data sig- nals before passing them on to the next device. Hubs cannot act as repeaters.
