100Base-TX Networks
The hub limit of a 100Base-TX network depends on the class of the hub in the network. With a Class I hub, the network is
limited to one hub. With a Class II hub, the network is limited to two hubs.
However, you can expand your 100Base-TX network that includes either class of hub by adding a Switch. With the Switch
added to your 100Base-TX network, you can separate that network into individual segments with their own collision domains.
In other words, you can connect one 100Base-T network with one or two hubs to the Switch, and you can connect another
100Base-TX network with one or two hubs to the Switch. You will then have one network with two collision domains.

Collapsed Backbone Link
Traditionally, bridges and routers have been used to link local area networks into one interconnected network. But these devices
involve difficult management and long traffic delays.
The Switch provides multi-port bridges with short delays, easy setup and maintenance, making it ideal for backbone links. Also,
the Built-in filtering on this hub decreases network traffic, while the multiple ports that communicate simultaneously increases
network performance.
One or more of your hub's 100Mbps or 1000Mbps ports can be used as a high-speed backbone link to other hubs serving as
collapsed backbones.
