DATA SHEET
OVE VIEW
The 3Com®Switch 5500 10/100 Family delivers
premium levels of performance, security and
reliability for robust switching at the enterprise
network edge. The family consists of Layer 2/3/4 Fast
Ethernet and Power over Ethernet switches, with
advanced features that can accommodate the most
demanding applications, offering resilient and secure
connectivity and the latest traffic-prioritization
technologies to optimize applications on converged
networks. Designed for maximum flexibility and
scalability, 3Com Switch 5500 models come with 24 or
48 10/100 ports, plus four active SFP-based Gigabit
Ethernet ports for stacking and uplinks.
The switches can be stacked up to eight units high in
one location, or they can be distributed over several
sites up to 70 km (43.5 miles) apart and connected via
Gigabit links to form a virtual “stack.” One stack can
provide up to 384 Fast Ethernet ports and may be
managed centrally as a single-IP entity. Each stack
offers chassis-like availability and resiliency over
traditional aggregated-trunk configurations with
patented 3Com XRN®(eXpandable Resilient
Networking) stacking technology.
Further expansion is possible via clustered stacking
technology, allowing single IP management for up to
32 devices from different 3Com switch families,
including the Switch 5500G, 5500, 4800G, 4500G, 4500,
4210 and 4200G.
KEY BENEFITS
ENTE P ISELEVEL PE FO MANCE
3Com Switch 5500 10/100 devices provide switching
capacity of up to 17.6 Gbps for 52-port models and
12.8 Gbps for 28-port models. Wirespeed and line-rate
performance is delivered on all ports within the stack.
Advanced Layer 3 routing—including OSPF, PIM-SM,
PIM-DM and RIP v1/v2—helps deliver optimal
performance and system response.
These switches offer Enterprise-class switching
features including more MAC addresses, static routes
and IP interfaces, greater number of virtual LANs
(VLANs), extended port mirroring, Layer 3 OSPF and
multicast routing, enhanced resiliency via 3Com XRN
stacking technology and IEEE 802.3af Power over
Ethernet (PoE) support.
HIGH AVAILABILITY FO C ITICAL
APPLICATIONS
XRN technology, a 3Com innovation, enables multiple
interconnected and stackable Layer 3 switches to be
managed as a single entity. Stack and switching fabric
setup is automated and provides a high level of
resiliency and continuous availability without adding
to network complexity.
After configuration, all switches actively share routing
intelligence and network loads—eliminating the wasted
bandwidth and added expense of a passive standby
unit. Ultra-fast failover recovery automatically
redistributes traffic among the other active units in
case a switch becomes disconnected or fails.
MULTILAYE SECU ITY
The Switch 5500 family provides integrated and
distributed security enforcement that can be managed
from a central location. Access control lists (ACLs)
help protect network resources from unauthorized
access and data corruption. User-based authen -
tication and DES 56/168-bit† encryption help secure
Layer 3 protocols and management controls such as

Premium stackable 10/100 switches with
maximum security, convergence features
and intelligence required by the most
demanding advanced enterprise networks

SS v2 and SNMP. IEEE 802.1X RADIUS/TACACS+
network login and RADIUS Authenticated Device
Access (RADA) enforce access control at the
network edge.
FLEXIBLE, SECU E FIBE CONNECTIONS
The Switch 5500-EI FX is ideally suited for applications
where security is of paramount importance, or where
long cable runs are required. This switch provides
connections on fiber infrastructures that are almost
impervious to electronic eavesdropping because they
use optical transmission. The switch uses 100BASE-X
SFP transceivers for its 24 100 MB connections,
providing the flexibility of running any mix of
100BASE-FX multimode fiber (up to 2 km/1.2 miles)
or 100BASE-LX10 single-mode fiber (up to 10 km/6.2
miles).
P IO ITY FO CONVE GED BUSINESS T AFFIC
Next-generation traffic prioritization features—
including advanced policy-based Class of Service/
Quality of Service (CoS/QoS), eight priority queues,
committed access rates, bandwidth limiting and
filtering and more—identify and optimize delay-
sensitive traffic such as voice and video. To help
assure this optimization, switches can be configured
to automatically isolate voice traffic from 3Com and
other IP telephony systems within a voice-dedicated
VLAN.
UNIQUE AC/DC POWE ED OPE ATION
3Com Switch 5500 products are the first stackable
switches to support multiple power schemes right out
of the box, with a choice of AC, AC and DC, or DC
operation. Select models also support IEEE 802.3af
PoE, enabling power to be injected out to the edge of
the network without the need to install additional
wires or upgrade existing power supplies.
EDUNDANT POWE SYSTEM SUPPO T
All 3Com Switch 5500 models support a redundant
power system (RPS) connection.
RPS units provide these benefits:
› For PWR switches, an RPS can deliver more power
budget for IEEE 802.3af Power over Ethernet than
what the switches alone can provide. For example,
the Switch 5500G PWR 52-port switch has a PoE
power budget of 300 Watts, which means that less
than half of the ports can provide the full 802.3af PoE
power of 15.4 Watts. With an RPS providing power, all
48-ports can provide a full 15.4 Watts of PoE power.
› They deliver redundant power to switches so there is
continued operation should the switch unit power
supply fail. This allows for continuous operation of
advanced Enterprise networks, particularly impor-
tant for converged networks running IP phones on
the network.

3Com H3C®RPS Systems
3Com switches are compatible with 3Com 3C RPS
solutions. These are enterprise-class power
redundancy systems that work with many 3Com
fixed-configuration switches. 3Com Corporation
manufactures networking equipment under the 3C
brand for sale into many markets.
These 3C RPS models are used with the Switch 5500:
› The T3C RPS 1000 is 1U high and provides multiple
power output connections to support multiple switch
units at the same time. Two power rectifiers can be
installed for 1+1 load sharing and power redundancy.
It supports switches with -54V RPS connections, and
delivers sufficient power to fully provision all PoE
ports of a switch with full power redundancy.
› The RPS 500 provides selective DC outputs of +12V
and -54V. This is a fixed-configuration 1U high unit
with a single power rectifier and a single power
connection. Sufficient redundant power is available
for provisioning a single Switch 5500 48- and 24-port
non-PoE unit.
POWE FUL, UNIFIED MANAGEMENT
The 3Com Operating System employed in the Switch
5500G is the same powerful software used in other
3Com enterprise stackable switches as well as in
3Com modular switch and enterprise router families.
This makes for an easy mix-and-match of networking
technologies with consolidated administration over
the entire network, as well as edge-to-core visibility
and control when using 3Com management
applications such as 3Com Enterprise Management
Suite and Network Director.
FUTU EP OOF INVESTMENT
Standards-based switching and management features
provide a networking solution that maximizes IT
investment and supports emerging standards.
Comprehensive IPv6 management features, as well as
IPv6 traffic filtering and classification, prepares your
network for this next generation IPv6 version while
maintaining full compatibility with today's more
common IPv4.
