Key Benefits
Unbeatable Resilience
The SuperStack 3 Switch 4900 family of
®
products supports 3Com's XRN
providing outstanding resilience and
reliability, at double the performance of
traditional resilient solutions. With XRN
technology, Layer 2 and Layer 3 networks
can be created with no single point of failure,
but still utilizing the full performance of
the network.
Performance
3Com's custom ASIC architecture delivers
wirespeed, non-blocking Gigabit Ethernet
switching across all ports, minimizing server
farm and network congestion. Further scale
performance using XRN technology, with
two units operating together as a single
management switching entity.
Advanced Network Control
Advanced Layer 2/4 functionality such as
multicast filtering, virtual LANs, and
multilayer traffic classification and
prioritization improve traffic control
across the network. XRN technology
supports two geographically distributed
switches managed as a single Layer 2 /
Layer 3 entity.
Gigabit Ethernet is Ideal for Server Farm Aggregation
The 3Com SuperStack 3 Switch 4900 Family
consists of four high-performance, wire-
speed, Layer 2 / Layer 3 / Layer 4 Gigabit
switches. These enterprise-class devices are
ideal for server farm aggregation in enterprise
environments.
• 3Com SuperStack 3 Switch 4900 comes
with 12 100/1000 copper ports.
• 3Com SuperStack 3 Switch 4900 SX has
12 1000BASE-SX ports.
• 3Com SuperStack 3 Switch 4924 comes
with 24 10/100/1000 copper ports.
• 3Com SuperStack 3 Switch 4950 has 12
10/100/1000 copper ports, six 1000BASE-SX
ports, and six flexible GBIC ports.
3 Switch 4900 Family
®
Layer 3
Switches support RIP v1/v2, OSPF, CIDR
technology
and UDP helper; the resilient capabilities of
XRN technology allow two units to share
IP interfaces eliminating the need for
complex implementations such as VRRP.
Advanced Security Capabilities
Secure network resources from unauthorized
access with RADIUS client support and
Access Control Lists.
High Availability
Robust features include link aggregation,
support for Rapid Spanning Tree protocol,
an optional Redundant Power Supply system,
and e-mail or pager status notification, all
ensuring maximum uptime for critical
applications.
Powerful Management
Comprehensive support within the 3Com
management application software suite,
including within the standalone package
3Com Network Director and with 3Com
Network Administrator for HP OpenView-
based management.
All these switches optionally support 3Com's
patented XRN technology allowing you to
quickly build a fully redundant aggregation
or network core solution out of a pair of
3Com Gigabit switches—delivering high
resiliency without complexity.
The Gigabit Multilayer Switching (GMS)
Software is the operating software of the
3Com SuperStack 3 Switch 4900 Family.
Now included with all new switches are
advanced features of the GMS Software,
formerly sold separately, features such as
OSPF routing and support for geographically
distributed XRN configurations.
