Companies today realize that the
booming e-business marketplace is pro-
viding them with amazing growth
opportunities. To take advantage of
these opportunities and sustain this
growth, IT managers must find a way
to boost network performance in synch
with their evolving e-business require-
ments. 3Com has developed a family of
modular, stackable switches designed to
help fast-growing companies add power
and performance to their networks
easily, economically, and with min-
imum disruption.

The SuperStack II Switch
1100/3300 family includes four high-
performance switches that can be
mixed and matched to achieve the per-
fect combination of cost and features
for desktop, workgroup, and backbone
aggregation. This is the first family of
switches that enables IT managers to
create a “virtual stack” of different
switches that act as one logical
switch—providing an easy and afford-
able way to build performance and
capabilities into the network as needed.

Each switch has a built-in matrix
port connector at the rear of the unit.
Two units can be connected with a
low-cost SuperStack II Switch matrix
cable; three or more units can be
stacked using a SuperStack II Switch
matrix module that delivers high-
speed/performance interswitch links—
eliminating bottlenecks between
switches. Stacked switches communi-
cate through matrix ports, so you don’t
consume valuable Fast Ethernet or
Gigabit Ethernet ports. You can mix
and match multiple switches to create
one virtual switch of up to 110

To make management even easier,
the SuperStack II 1100/3300 family
features Web-based monitoring and
control, so IT staff can troubleshoot or
configure a stack from any location.
Embedded Remote Monitoring
(RMON) support provides detailed
information on network traffic. The
switches also ship with 3Com
Transcend Network Supervisor, an easy
and automatic management solution
specifically designed for small- and
medium-sized businesses.

Switch 1100/3300 family supports a
broad range of expansion modules
(such as Layer 3 switching, Gigabit
Ethernet, or ATM support) to add con-
nectivity or functionality as needed.

What’s more, all four models share
the same software, reducing training
time and ensuring flawless interoper-
ability. Companies can even bolster
their e-business initiatives by adding
voice and video to their networks with
a rich traffic management feature set,
including:
• Policy enforcement with Fast IP,
