HIGH AVAILABILITY 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

PRIORITY FOR CONVERGED 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.
