Using the Centillion EtherSpeedII Switch Modules
2-8 207344-B
Desktop Switch and Frame-to-Cell Converter
For wiring closets with higher densities and lower bandwidth requirements, you
can use the EtherSpeedII 10/100BASE-T switch module to aggregate traffic from
other stackable switch products such as the BayStack
™
301 and BayStack 350T
switches (providing frame switching) to an ATM backbone (providing cell
switching). The stackable switches and the 20 RJ-45 10/100 Mb/s switched
Ethernet ports on the EtherSpeedII 10/100BASE-T switch module provide
desktop connectivity.
Figure 2-7
shows a network with EtherSpeedII 10/100BASE-T switch modules
used to connect BayStack 301 and BayStack 350T switches to the Centillion 50/
100 chassis in a data center. The 10/100 Mb/s ports on the EtherSpeedII switch
module provide high-speed connections to the BayStack switches. The
EtherSpeedII switch module provides switched 10 Mb/s or 100 Mb/s capability
for higher-bandwidth desktop connectivity. You can upgrade to 100 Mb/s with a
client NIC upgrade.
