Planning a Network with the Model 5625HD Switch Module Giving a Server a Dedicated Port Moving a server from a 10 Mb/s shared-media connection to a dedicated port on the Model 5625HD switch module improves server response time and increases throughput capacity. For even higher performance, the server could be upgraded to 100 Mb/s and the Model 5625HD switch module would autonegotiate for 100 Mb/s. In Figure 2-2, the “Before” example shows clients and servers sharing the same network segment.
Using the Model 5625HD EtherSpeed Switch Module Replacing a Bridge Using a switch instead of a bridge in the network can increase the aggregate network bandwidth. The “After” example in Figure 2-3 shows one server connected to a dedicated 10BASE-T port. It also shows the other server and additional clients attached using dedicated 100BASE-TX connections. This network configuration allows you to have switched 10 Mb/s Ethernet along with segmented 10 Mb/s Ethernet to conserve ports.
Planning a Network with the Model 5625HD Switch Module Desktop Switch with ATM Uplinks In the example shown in Figure 2-4, the Model 5625HD switch module provides up to 24 RJ-45 switched Ethernet (10/100 Mb/s) ports to connect to desktops, with redundant high-speed ATM OC-3c and OC-12c ports to connect to an ATM backbone.
