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. This network configuration can support small to large wiring closets.
Figure 2-4 on page 2-8
shows a sample network providing ATM uplinks to a
Model 5000BH/BHC chassis. Servers are connected to the network through the
Model 5000BH/BHC chassis, and network stations are connected to the 10/
100BASE-T ports on the Model 5625HD switch modules. The chassis are
dual-homed with ATM OC-3c and OC-12c uplinks to the Model 5000BH/BHC
chassis. Model 5000BH/BHC chassis can be interconnected with multiple ATM
links.
