"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.
