2-3Collapsed Backbone

The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and

Gigabit Ethernet installations in which significant growth is expected in

the near future. You can easily build on this basic configuration, adding

direct full-duplex connections to workstations or servers. When the time

comes for further expansion, just connec t to another hub or switch via one

of the switch’s Fast Ethernet or Gigabit Ethernet ports.

In the figure below, the switch is operating as a collapsed backbone for a

small LAN. It is providing dedicated 10 Mbps full-duplex connections to

workstations and 100 Mbps full-duplex connection s to power users and

servers. In addition, connected IP phones and wire less access points are

receiving PoE power from the switch.
