Stack the Hubs
• Unplug the hubs.
• Use an Intel Cascade Cable to connect the
hubs. Hubs can be stacked up to eight
high (mixed 12- or 24-port).
• When properly connected, the entire stack
will act as a single repeater with two
segments (10Mbps and 100Mbps). The
top hub in a stack will be numbered hub 1.
Bridge the 10Mbps and
5
100Mbps Segments
• The hub's internal bridge is active by
default and bridges the 10Mbps and
100Mbps segments (collision domains).
• If you are bridging the 10Mbps and
100Mbps segments externally (for
example, through a 10/100 switch) be sure
to turn off the hub's internal bridge.
• If you have a stack of hubs, any bridging
button on any hub in that stack will enable
or disable bridging for the entire stack.
Add Additional
6
Modules
• The 12-port 220T can accept additional
modules (refer to the User Guide).
• Use the modules to manage a stack,
connect to devices at full-duplex, or to
extend the network to another building
or beyond 100 meters.

Never daisy-chain hubs
running at 100Mbps with UTP
cable. Doing so violates the
IEEE 802.3u Fast Ethernet
standard for Class I hubs.
