Collapsed Backbone
This switch is 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 for
workstations or servers. When the time comes for further expansion, just connect to
another hub or switch using one of the Fast Ethernet ports built into the front panel
or using an SFP transceiver plugged into one of the Gigabit Ethernet ports.
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
1 Gbps full-duplex connections to power users and servers. In addition, connected
IP phones and wireless access points are receiving PoE power from the switch.
