3Com SWITCH 4050 User manual

DATA SHEET
Key Benefits XRN Technology
3Com XRN™(eXpandable Resilient
Networking) technology allows
implementation of high availability
configurations using two intercon-
nected Switch 4050s, Switch 4060s, or
Switch 4070s, scaling the backbone to
48 wirespeed Gigabit Layer 3 switch-
ing ports.
Performance
3Com’s custom ASIC architecture
delivers 56 Gbps multilayer switching
capacity, providing wirespeed
performance across all ports, with a
forwarding rate of more than 40 Mpps,
minimizing network congestion.
Reliable and Serviceable Hardware
A durable, 2RU metal chassis offers
high availability hardware features
such as redundant, load sharing and
hot-swappable power supplies, in
addition to hot-swappable fan trays
and GBIC and SFP transceivers.
High Availability Features
Switch software and management
features, including Link Aggregation
(IEEE 802.3ad), Resilient Links,
Spanning Tree and Rapid Spanning
Tree (IEEE 802.1w), seven groups
of RMON, email alerts, backup and
restore, and dual flash images,
facilitate highly available network
designs for the core backbone.
Advanced Network Control
Advanced Layer 2 and Layer 3 func-
tionality such as multicast filtering,
virtual LANs, and multilayer traffic
classification and prioritization improve
traffic control across the network.
Layer 3 Switching
Layer 3 switching capabilities such as
IP unicast routing using static routes,
OSPF, RIP/RIPv2, CIDR, and UDP
Helper, enhance performance,
provide network control and security,
and enable logical network segmentation.
Advanced Security Capabilities
Security features such as RADIUS
switch login and routed Access Control
Lists ensure authorized user access to
management interfaces and network
resources. Application Filtering enables
the switch to identify and discard
unauthorized applications from
consuming network bandwidth.
Powerful Management
An intuitive interface eases network-
wide prioritization of switch traffic.
The switches also support Roving
Analysis Port (RAP) for analysis of
network traffic, and a VLAN setup
wizard for ease of configuration.
3Com®Network Supervisor (trial copy
included) discovers, maps, monitors,
and issues alerts for easy network
administration. The switches are also
supported by 3Com Network Director
and 3Com Network Administrator for
more advanced management needs.
Flexibility
A combination of integrated 1000BASE-
SX, 10/100/1000, GBIC and SFP ports
supports a variety of cabling plants
and network designs. An expansion
slot accommodates an optional four-port
Gigabit module for even greater
flexibility.
3Com®Switch 40x0 Family

"3Com offers a
revolutionary approach
to build enterprise LAN
cores with innovative
technology that breaks
new ground in the
networking industry."
Zeus Kerravala, vice president of
Enterprise Infrastructure, Yankee
Group
The 3Com®Switch 40x0 Family consists
of three high-performance, wirespeed,
Layer 2 / Layer 3 / Layer 4 Gigabit
switches, all with "hot swappable"
dual redundant power supplies and
fans. These enterprise-class devices
are ideal for creating a highly resilient
core switching environment for a small
campus or building-wide network, or
for aggregation of workgroups in a
larger network environment.
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 three models each have 24 ports,
of different Gigabit port combinations,
with flexibility and expansion provided
through SFP (Small Form factor Plug-
in) or GBIC transceivers:
• 3Com Switch 4070 provides maximum
media flexibility with 24 SFP slots.
• 3Com Switch 4060 has 12 1000BASE-
SX ports, six GBIC ports, and six
integrated 10/100/1000 ports.
• 3Com Switch 4050 has six 1000BASE-
SX ports, six GBIC ports, and 12
integrated 10/100/1000 ports.
The Gigabit Multilayer Switching (GMS)
Software is the operating software of
the 3Com Switch 40x0 Family. Now
included with all new switches are
advanced features of the GMS Software,
formerly sold separately: OSPF routing
and support for geographically distrib-
uted XRN configurations.
Two configurations of XRN-enabled
switches are supported by the Switch
40x0 Family:
• Two locally connected XRN-enabled
switches. Required for this is one
3Com XRN Interconnect kit (3C17715)
to connect the two switches.
• Two geographically distributed
XRN-enabled switches. Required
for this are two 3Com 4-Slot GBIC
Modules for SuperStack®3 Switch
4900 and Switch 40x0 (3C17714),
one for each switch in the configu-
ration, along with the quantity of
GBIC modules to support the desired
fiber connections. One connection
between the two switches is required,
but for added bandwidth, up to four
connections can be aggregated. In
this configuration, fiber connections
must be of the same type and can
only be used for XRN connections.
XRN Technology
XRN™–eXpandable Resilient
Networking–technology is patented,
innovative 3Com technology that
allows IT managers to build affordable
networks that are highly resilient and
deliver exceptional performance and
flexibility. With XRN technology,
multiple interconnected Gigabit
switches behave as a single management
switching entity. The units actively
share the load in normal operation,
yet one will nearly instantly recover
all connections should the other unit
or its connections have a failure. XRN
technology is supported by the 3Com
SuperStack 3 Switch 4900 for server
aggregation and by the 3Com Switch
40x0 for building core networking. It
is high resiliency networking without
complexity.
