OVERVIEW

The award-winning 3Com

SuperStack

provide wirespeed 10/100 Fast Ethernet connectivity with a choice of

Gigabit downlinks and are specifically designed for Enterprise work-

group environments. Available in 24 and 48-port models covering

important network interface types including Power over Ethernet(PoE),

and 100BASE-LX10, with two Gigabit module slots on every unit, these

switches display resiliency, flexibility in deployment, and advanced

security features. The SuperStack 3 Switch 4400 Family also boasts

advanced Quality of Service features that can reduce the latency of

packets through the network, with specific traffic prioritization

improving the delivery of converged data such as voice and high quality

video over IP . Supported by 3Com Global Services and 3Com's outstanding

Limited Lifetime Warranty, these switches are ideal for enterprises

wanting flexible, resiliant, manageable and secure networks.

ADVANCED SECURITY

The Switch 4400 family provides advanced security features for net-

work data and management traffic.

User network login with IEEE 802.1X and RADIUS, combined with

RADIUS Authenticated Device Access (RADA), provides secure flexible

network access control at the edge of the network. Local authentication

for up to 50 IEEE 802.1X users and RADA devices offers added flexibility

in the absence of a centralized RADIUS server, and supplies a backup

solution in case of server failure or connectivity issues.

Authenticated users can be placed automatically into a specific VLAN,

creating an even more secure network environment. The Private Ports

feature can isolate edge ports to ensure user privacy. Access Control

Lists (ACLs) allow or deny traffic based on specific subnet, or individ-

ual IP address. SNMP v3 secure encrypted management, Secure Shell

(SSH), management VLAN, and management station "trusted IP address"

lists help protect the network from rogue management threats.

RESILIANT NETWORKING

Hot-swappable stacking of up to eight units, or 384 10/100 ports, allows

for scalable site expansion with continuous operation. Stack-wide link

aggregation (LACP) enables high-performance connectivity of up to

4Gbps to the core of the network in a single aggregated link, with ports

on different units for added resiliency to maximize network availability.
