Configuration used in your network.
Switch 3300 FX as a The example in Figure 3 shows how a Switch 3300 FX can segment a
Segmentation Switch network of shared 10Mbps and 100Mbps connections. There is a 10/100
shared segment on each floor, and these segments are connected to the
Switch which is positioned in the basement.

backbone for both shared and switched network segments.

Network Configuration Example
Switch 3300 FX as a The example in Figure 5 shows how a Switch 3300 FX can be used for a
Desktop Switch group of users that require dedicated 10Mbps or 100Mbps connections
to the desktop. The Switch has a SuperStack II Switch 1000BASE-SX
Module that allows it to provide a Gigabit Ethernet link to a SuperStack II
Switch 9000 SX in the basement.
