Intel Express 10/100 Fast Ethernet Switch

Typical Configurations

Configuring the mixed 10 and
100 Mbps workgroup environment

In the mixed 10 and 100 Mbps environment, workgroup clients should
be connected to a hubs such as the Intel Express 10/100BASE-TX
Stackable Hub. All hub stacks should be connected to the Express
10/100 Switch. Servers or busy workstations should also be connected
directly to the 10/100 Switch.
