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.
