THE
PS H
UB
Segments and
Port Switching
The PS Hub has four separate internal repeaters (called
segments
)
which you can use to create your workgroups. You can switch the
hub’s ports to any of these segments (called
port switching
). With the
segments and port switching, you can easily 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 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 Figure 1-8
