Application Examples

The TigerStack II 10/100/1000 is not only designed to segment your
network, but also to provide a wide range of options in setting up network
connections and linking VLANs or IP subnets. Some typical applications
are described below.

Collapsed Backbone

The TigerStack II 10/100/1000 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 up to 24/48 workstations or
servers. 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 connect to another hub or switch using one of the
Gigabit Ethernet ports built into the front panel, a Gigabit Ethernet port
on a plug-in SFP transceiver, or a 10G transceiver on an optional module.
In the figure below, the 48-port switch is operating as a collapsed backbone
for a small LAN. It is providing dedicated 10 Mbps full-duplex
connections to workstations, 100 Mbps full-duplex connections to power
users, and 1 Gbps full-duplex connections to servers.
