***3Com Further Extends the 3Com Switch 7700 Family of Modular
Gigabit Ethernet Switches to Boost High-Performance Networks

MARLBOROUGH, Mass.
April 28, 2004

3Com Corporation expanded its modular chassis Switch 7700 family.
IT managers will be able to use a Switch 7700 4-slot chassis to
add modularity for enterprise workgroup aggregation or as a small
network core. They can also deploy 20-port Gigabit modules across
the range of the Switch 7700 family, effectively more than
doubling the Gigabit port density of these switches for
enterprise applications.

The 3Com Switch 7700 4-slot chassis gives enterprise customers
the option of having a high-performance chassis switch for
workgroup aggregation, while the new 20-port Gigabit modules
scale switch port density of the entire Switch 7700 family. Mid-
sized enterprises can also use the Switch 7700 4-slot chassis as
a small building core switch and, as the business grows into a
larger-sized enterprise, scale the network with 3Com's higher-end
Switch 7700s, including the enterprise-level, 8-slot redundant
model, for secure, converged networks.

The Switch 7700 4-slot chassis has a single switch fabric slot
and three slots for switch modules. Its design allows for a 4-
port sub-module on the switch fabric, a less-expensive option for
adding a small number of fiber or copper Gigabit uplinks without
taking up a full module slot. Total capacity is 64 Gigabit ports
or 144 10/100 ports. 3Com offers two 20-port Gigabit modules for
the Switch 7700 family. The first is a 1000BASE-T (10/100/1000)
20-port module for copper Gigabit connections. Also available is
a 1000BASE-X (SFP) 20-port module for flexible fiber Gigabit
connections.
