Desktop Switch and Frame-to-Cell Converter

For wiring closets with higher densities and lower bandwidth requirements, you

can use the Model 5625HD 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 24 RJ-45 10/100 Mb/s switched Ethernet ports on the

Model 5625HD switch module provide desktop connectivity.

Figure 2-7 shows a network with a Model 5625HD switch module u sed to conne ct

BayStack 301 and 350T switches to the Model 5000BH/BHC chassis in a data

center. The 10/100 Mb/s ports on the Model 5625HD switch module provide

high-speed connections to the BayStack™ switches. The Model 5625HD switch

module provides switched 10 Mb/s or 100 Mb/s capability for higher-bandwidth

desktop connectivity and can upgrade to 100 Mb/s with a client NIC upgrade.
