Desktop Switching
Figure 2-1 illustrates a BayStack 70-8T 10/100 Ethernet Switch used as a desktop
switch to rebuild a small network that enables users to have 100 Mb/s access to a
file server or network center. You can use the BayStack 70-16T 10/100 Ethernet
Switch or BayStack 70-24T 10/100 Ethernet Switch as a desktop switch, in a
similar application, if you have more users or devices to connect.
You can replace your existing 10BASE-T hub with a BayStack 70 Series 10/100
Ethernet Switch in order to access devices with various transmission speeds or to
connect to a larger number of users.
