1-8 CHAPTER 1: ABOUT THE PS HUB
Segments and
Port Switching
The PS Hub has four separate internal repeaters (called segments)
which you can use to create your work groups. You can switch the
hub’s ports to any of these segments (called port switching). With the
segments and port switching, you can easi ly create your workgroups.
How the PS Hub Segments Work
In a stack of PS Hubs, four segments are carried between the hubs by
the cascade cables. These segments are four separate networks internal
to the stack, as shown in Figure1-7.
Figure 1-7 Cascaded Segments
Each PS Hub has four internal segments. These segments are separate
internal repeaters, and can connect to or remain isolated from their
associated cascaded segments, as shown in Figure1-8.
