KEY BENEFITS

(CONTINUED)

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 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 authentication and DES 56/168-bit

encryption help secure Layer 3 protocols and management controls

such as SSH v2 and SNMP. IEEE 802.1X RADIUS/TACACS+ network

control at the network edge.

FLEXIBLE, SECURE FIBER 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

10/100 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). Plus, the Switch 5500-EI FX

supports all the advanced EI features.

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 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. Some EI 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. An available Redundant Power System can provide supple-

mental N+1 power across all PoE ports in the system.
