Extending the 100 Mbps network topology
You can extend the network topology only by connecting hubs to a
switch, bridge, or router. You can’t extend the topology by daisy-
chaining hubs together. In the example below, the network diameter is
extended to 400 meters by connecting the two hub stacks to an Intel
Express 10/100 Fast Ethernet Switch. Each stack is a separate
collision domain.

10 Mbps-only environment
In a 10-Mbps only environment, you can connect hubs using an Intel
Cascade Cable or CAT 3, 4, or 5 TPE cables. Connect to devices
(switches, workstations, servers, and so on) with CAT 3, 4, or 5 TPE
cables. The distance between hubs or between a port and an attached
device can’t exceed 100 meters when using TPE cabling.

Category 3, 4, or 5 TPE (100m max.)
All hubs in a stack share
10 Mbps of bandwidth and
count as one repeater hop.
100 Mbps
shared among
all hubs in stack
If you intend to install an
optional Management
Module in a 12-port hub,
place the hub at eye
level. This makes it
easier to read the
module’s LCD panel.
