Using the Centillion EtherSpeedII Switch Modules
2-6 207344-B
Desktop Switch with ATM Uplinks
In the example shown in Figure 2-4, the EtherSpeedII 10/100BASE-T switch
module provides 20 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
also illustrates a sample network providing ATM uplinks to a
Centillion 50/100 chassis. Servers are connected to the network through the
Centillion 50/100 chassis, and network stations are connected to the
10/100BASE-T ports on the EtherSpeedII 10/100BASE-T switch modules. The
chassis are dual-homed with ATM OC-3c and OC-12c uplinks to the Centillion
50/100 chassis and the Model 5000/5005BH chassis. These chassis can be
interconnected with multiple ATM links.
