Collapsed Backbone
These switches are an excellent choice for mixed Ethernet, Fast Ethernet, and
Gigabit Ethernet installations where significant growth is expected in the near future.
In a basic stand-alone configuration, it can provide direct full-duplex connections to
workstations or servers. When the time comes for further expansion, just connect to
another hub or switch using one of the Fast Ethernet or Gigabit Ethernet ports built
into the front panel.
In the figure below, the switch is operating as a collapsed backbone for a small LAN.
It is providing dedicated 100 Mbps full-duplex connections to workstations and
1000 Mbps full-duplex connections to power users and servers. In addition,
connected IP phones and wireless access points are receiving PoE power from the
switch.
