Cisco FASTHUB 412 12 PORT 10/100 STACKABLE Specification Guide
FastHub Stacks C-3
Interconnecting and Cascading Hubs
You can use Class II repeaters to build networks with two or more repeaters or hub stacks
in a single collision domain. With two Class II repeaters, you can have a short cable
segment connecting the repeaters while maintaining 100-meter Category 5 connections to
the attached stations. Using more than two repeaters in a single collision domain requires
considerably shorter connections to attached stations. Figure C-2 shows the connection of
two hub stacks through the front-panel 10/100 ports to form a collision domain with up to
190 ports.
