Key Benefits:

Performance
Non-blocking gigabit switching
performance delivers a forwarding rate
of more than 41 million packets per
second across all ports, minimizing
network congestion.
Feature-Rich Network Control
Layer 2 switching functionality such as
multicast filtering, virtual LANs, link
aggregation, and RMON supports
demanding business applications.
High Availability
Robust availability features include
link aggregation, support for
Rapid Spanning Tree,Redundant Power
Supply system, and e-mail or pager status
notification,ensuring maximum uptime
for critical applications.
Layer 3 Switching
Support for wire-speed Layer 3
switching capabilities will enhance
performance, provide network control
and security, and enable logical segmentation
of networks based on VLANs.
Prioritize Business Critical Traffic
Advanced Class of Service support
including support for four queues per
port, 802.1p, and multilayer packet
classification capabilities to allow
prioritization of critical traffic.
Value
Affordable price-per-port enables
cost-effective deployment of high
performance Gigabit switching at the
server farm, wiring closet or the
network backbone.
Scalability
Support for up to 28 switched Gigabit
ports per switch protecting network
investment as the demand for higher
Gigabit port density increases.
Transparent Webcache Redirection
Web traffic can be redirected
automatically to a 3Com SuperStack 3
Webcache device, improving web
performance and easing network
administration.
Powerful Management
3Com Network Supervisor application
is included with discovery, mapping,
monitoring, and alerting for easy
network administration. Intuitive interface
speeds network-wide set-up of
switch traffic prioritization.
Lifetime Limited Warranty
Ensures peace of mind. Lifetime
warranty includes fans and power
supplies.
