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.
