Catalyst Express Switch Network Example

Figure 1-2is an example of how to use the different Catalyst Express switches to enable communication between network users and to provide them access to network resources.

Any of the Catalyst Express 520 switches can be Switches A, B, C, and D in this network. To take full advantage of the different models of the Catalyst Express 520 switch platform, use the one that is designed for the type of connections that you require.

•Switches A and B: Use the Catalyst Express 520G-24TC-K9 model. It has the most Gigabit Ethernet ports, and it is best suited to providing 1000-Mb/s connections between switches and to servers. Multiple connections between the switches ensure that users maintain network access if any of the switches becomes overused or unavailable.
