Switch 5500 family of
stackable switches offer the ideal network-
edge solution for delivering premium levels
of performance, security, and reliability.
Their robust features enable the enterprise
network to become more future-proof,
resilient, standards-based, secure, and
converged than ever before.

Their robust features enable the enterprise
network to become more future-proof,

converged than ever before.
These workgroup switches run on the 3Com
Operating System, an operating system that
is shared across our premium enterprise
offerings—including the 3Com Switch 8800
and 7700, and 3Com enterprise routers. This
allows the management of an entire distributed
switching and routing infrastructure from a
single CLI or SNMP management platform
such as 3Com Enterprise Management Suite
or 3Com Network Director. The end result is
a more unified network environment and
improved edge-to-core visibility and control.

The 3Com Switch 5500 family includes
next-generation Layer 2/3/4, Fast Ethernet
switches that are ideal for the most demanding
wiring-closet applications. They offer flexible
and scalable connectivity for a heterogeneous
mix of data, voice, video, and other business-
critical services and are particularly suited
for building highly available and resilient
architectures. These Switch 5500 models
come with 24 or 48 10/100 ports plus four
active SFP-based Gigabit ports.

Standard-image (SI) and enhanced-image (EI)
software models provide for the best fit for
performance and budget requirements. The
3Com Switch 5500-SI supports robust, resilient
stacking up to eight units high. The stack is
connected via the built-in SFP-based Gigabit
ports that provide plug-and-play hardware
detection and automated configuration.

3Com Switch 5500-EI enhanced models
support our innovative 3Com XRN stacking
technology, which allows the creation of
an eight-unit stack that offers even better
availability and resiliency over traditional
aggregated-trunk configurations. The entire
stack can be managed as a single-IP manage-
ment entity, even if individual units are
geographically distributed up to 70 km
(43.5 mi) apart. All switch units are active,
eliminating the wasted bandwidth and cost
of a passive “standby” unit. There is no
master/slave relationship among the units.
Instead, all switch units share routing table
information dynamically. Should a connection
fail or unit become disconnected, within
seconds, traffic loads are automatically
redistributed among the remaining active
systems.

Also available as an EI model in the Switch
5500 family is a 100BASE-FX switch ideally
suited to applications where security is of
particular concern or where long cable runs
are required. Fiber optic cabling is almost
impossible on which to eavesdrop and thus
is ideal for high security environments.
The Switch 5500-EI FX 28-Port uses
100BASE-X SFP pluggable transceivers for
its 24 connections at 100Mbps, providing
the flexibility of running any mix of
100BASE-FX multimode fiber (up to 2 km
or 1.2-mi) or 100BASE-LX10 single-mode
fiber (up to 10 km or 6.2 mi). The Switch
5500 FX supports all the advanced 5500-EI
family features such as Layer 2/3/4 switching
and XRN stacking.

Advanced QoS features, including application-
aware traffic controls and filtering, optimize
network bandwidth for lag-sensitive voice
and video transmissions. Centrally controlled
security features enable the enforcement
of data security across the network,
protecting users and devices from unauthorized
access and corruption. Advanced Layer 3
routing, such as OSPF, PIM-SM and PIM-DM
(EI-models only), and RIP v1/v2, help optimize
network performance and system response.

3Com Switch 5500 products are the first
stackable workgroup switches to support
multiple power schemes right out of the
box—AC, AC and DC, or DC operation.
Specific EI models also support IEEE 802.3af
Power over Ethernet, enabling power to be
pushed to the edge of the network without
having to install additional electrical wiring
or upgrade existing power supplies.
