O ER IEW
The 3Com®Switch 5500G 10/100/1000 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 Gigabit
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 5500G models come
with 24 or 48 Gigabit ports, and offer optional modules for 10-Gigabit
and SFP Gigabit uplink connections.
The switches can be stacked up to eight units high using patented
3Com XRN®(eXpandable Resilient Networking) technology. One XRN
stack can provide up to 448 Gigabit Ethernet ports, with 96 Gbps
resilient stacking bandwidth, all centrally managed, with high-end
enterprise chassis-class availability.
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, 4500G, 4210 and 4200G.
KEY BENEFITS
ENTERPRISE-LE EL PERFORMANCE
3Com Switch 5500G 10/100/1000 devices provide switching capacity
of up to 240 Gbps for 48-port models and 192 Gbps for 24-port models.
Wirespeed 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.
BUILT FOR FLEXIBILITY AND GROWTH
The 3Com Switch 5500G family consists of five models: choose 24 or 48
Gigabit ports, with or without PoE; a fifth SFP model offers 24 SFP
Gigabit ports. Four ports on each of these models are dual-purpose or
“dual-personality,” functioning as either 10/100/1000 or with fiber
Gigabit SFPs; two of these four SFP ports also support Fast Ethernet fiber.
All models come with an applications module slot for adding ports
or capabilities. Install an 8-Port SFP Gigabit module, or a 1- or 2-port
10-Gigabit module. Use this in the future to add a 3Com Open Services
Networking (OSN) module.

HIGH A AILABILITY FOR CRITICAL 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.
MULTILAYER SECURITY
The Switch 5500G 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 authentication and DES 56/168-bit†
encryption help secure Layer 3 protocols and management controls
such as SS v2 and SNMP. IEEE 802.1X RADIUS/TACACS+ network
login and RADIUS Authenticated Device Access (RADA) enforce access
control at the network edge.
PRIORITY FOR CON ERGED BUSINESS TRAFFIC
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 POWERED OPERATION
3Com Switch 5500G 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. The
customer-swappable power supply unit enables non-PoE models to be
easily upgraded to PoE capability. An available Redundant Power System
can provide supplemental N+1 power across all PoE ports in the system.
POWERFUL, 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 the 3Com Switch 8800 and Switch 7700 modular switch
families and the Router 6000, 5000 and 3000 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 3Com Network Director.

SPECIFICATIONS
(CONTINUED)
3Com has tested and qualified a Redundant Power System (RPS) solution
designed for the Switch 5500G family by Eaton Powerware Corporation,
a leading global provider of power quality and management solutions.
The Powerware DC RPS systems come in either 3RU or 6RU form-factors,
delivering up to 9,000W of DC power to a stack of Switch 5500G units.
The 3RU RPS unit houses up to three hot-swappable rectifiers supplying
up to 4,500W of power that supports up to eight separately-fused DC
outputs, while the 6RU unit can house up to six hot-swappable rectifiers
provisioning a total of 9,000W.
The RPS supports SNMP management, including MIB II, which is easily
accessible through the built-in RJ-45 or serial port. It is fully compatible
with the IEEE 802.3af Power over Ethernet standard, providing supple-
mental power for the 3Com Switch 5500G PWR models.
With this RPS, all 384 10/100/1000 ports on a stack of eight Switch
5500G PWR 48-port units can receive the industry standard 15.4W
of power per port, with N+1 power redundancy.
The RPS ships with the power input fully configured and can be
connected to a UPS with battery backup. For more details, refer to
www.3com.com/rps.

ßDue to space constraints, the witch 5500G 2-Port 10G (XFP) Module can accomodate only one
10GBA E-CX4 XFP.
€Dual-mode 100BA E-X FPs provide 100 Mbps fiber connectivity in the last two 1000BA E-X FP
ports of witch 5500G models, and in all ports of the 8-Port 1000BA E-X FP Module.
ORDERING
INFORMATION
Note: witch 5500G power supply units (P Us) are changeable and upgradeable. Because of this
flexibility, for unit identification purposes during registration and ervice and upport, these non-
orderable KU references are used:
• 5500-G EI 24-port unit, irrespective of P U 3CR17254-91
• 5500-G EI 48-port unit, irrespective of P U 3CR17255-91
• 5500-G EI 24-port FP unit, irrespective of P U 3CR17259-91
Power supplies are identified using the KUs under " pare Components", above.
