FastHub 100 Series Hubs

FastHub 100 Series Hubs

Product Overview

The FastHub 100 series of standalone 100BaseT hubs provides the lowest-cost 100-Mbps performance for power workgroups and users where management is not critical. Available in 4-, 8-, and 16-port densities, these Class II hubs offer a cost-effective solution for a range of workgroup sizes and are a key element in Cisco's end-to-end solutions.

The FastHub 100 series' unique Class II design lets you connect two hubs together, creating a collision domain of up to
30 ports. The FastHub 100 series hubs can connect to other Class II hubs, including the FastHub 300 and FastHub 200 series. The Class II design also lets you distribute and connect hubs in separate wiring closets, without an intermediate switch, bridge, or router.

The FastHub 100 series of hubs consists of the following models:
A 4-port 100BaseTX hub (see Figure 9-8) that works with 100BaseT switches to provide affordable, 100-Mbps performance to multiple workstations
An 8-port 100BaseTX hub (see Figure 9-9) for connecting small workgroups over UTP cabling
A 16-port 100BaseTX hub (see Figure 9-10 and Figure 9-11) for connecting workgroups consisting of up to
16 workstations over UTP cabling
