Using a Switch to Connect
Hubs
Integrating switching into the network enables network segmentation,
which increases the total capacity and performance. You can add 100
Mbps workgroups to the network and connect them to individual ports
on a Fast Ethernet switch.
The illustration below shows how Express Stackable Hubs interface
with a switching hub to increase the total capacity and performance of
an entire network.
Three groups of 100 Mbps workstations are connected to three separate
hub stacks. The Express Hubs are stacked to provide multiple ports per
stack. This network shows three hub stacks that support individual
workgroups.
A 100BASE-FX uplink module is installed in one of the Express Hubs,
connecting the hub stack to the switching hub through a 100 Mbps
fiber link. Two servers equipped with 100 Mbps LAN adapters are
connected to the switch to provide centralized services to workstations
in all three workgroups.
