SWITCHING

DATA SHEET

OVERVIEW

The 3Com®Switch 4210 is a family of Layer 2 entry­level 10/100 LAN switches with enterprise-class QoS,
security and management features, delivering high
value for network administrators looking for an
economical edge device. Available Power over
Ethernet (PoE) models are ideal for voice over IP and
wireless networking installations; non-PoE models
are also available for simple port expansion.

Setting them apart from lower-end “smart managed”
devices, the Switch 4210 supports an industry-standard
Command Line Interface, Web-based administration,
and SNMP management. Switches can be clustered in
any combination up to thirty-two units for simplified
administration.

In addition to rack-mount 26- and 52-port models, the
Switch 4210 is available in small form factor units with
nine or 18 ports for enterprise branch and small
workgroup deployments, in both PoE and non-PoE
variants, with the same manageability as the larger
rack-mount versions.

The Switch 4210 comes with 3Com’s limited lifetime
warranty covering the unit, power supply and fan;
Advanced Hardware Replacement with next business
day shipment is available in most regions.

KEY BENEFITS

ECONOMICAL, FLEXIBLE LAYER 2 NETWORKING

3Com Switch 4210 switches deliver enterprise-class
10/100 Layer 2 edge connections with Gigabit uplinks.
All models are wirespeed and non-blocking for
optimum performance. These switches feature

combination ports that can run in one of two modes:
10/100/1000 Mbps connections over copper Ethernet
cabling, or 100 or 1000 Mbps over fiber cabling using
SFP mini-GBIC technology.

POWER OVER ETHERNET FOR VOICEREADY
NETWORKING

Industry-standard IEEE 802.3af Power over Ethernet is
supported on three switches: the 9-, 18- and 26-port
PWR models. These switches are ideal for workgroups
where phones or wireless access points connect
together with user end stations, reducing costs and
simplifying the installation of converged voice and
wireless networks by providing power over the same
Ethernet cabling as used for data.

PLUG AND PLAY CONVENIENCE

The Switch 4210 automatically selects the optimal
speed and duplex mode of cables connected to it,
preventing mis-configuration of the network. The
switches also detect and adjust to cross-over or
straight-through cable connections through its auto­MDI/MDIX feature, which eliminates the need for
specific cables.

Link Aggregation Control Protocol (IEEE 802.3ad)
further simplifies network configuration, automatically
sensing the presence of duplicate links and
aggregating them into trunks, thereby maximizing
network traffic flow capability.

SECURE NETWORKING

The Switch 4210 helps ensure secure network access
using standard IEEE 802.1X network login with
RADIUS Authenticated Device Access (RADA), a 3Com
innovation. RADIUS support enables user

authentication, while the switch is also able to
a

uthenticate attached devices (IP phones, for example)

via their MAC address for additional endpoint security.

A "Guest" VLAN feature allows temporary users on
the network to access the internet, for example, while
restricting broader access to sensitive internal
resources.

Additional security measures—Secure Shell version 2
(SSH v2) and SNMP v3 with authentication and
encryption of network management traffic—are
enforced when accessing switch management utilities.

ENTERPRISELEVEL NETWORK CONTROL AND
MANAGEMENT

The Switch 4210 family is easy to use and manage,
designed to increase business productivity by reliably
supporting business applications.

Features usually found only in higher-end enterprise
switches are included: a robust industry-standard
command line interface is available, along with an
embedded web-based interface; the switch also
functions with SNMP management tools like the
3Com Enterprise Management System or 3Com
Intelligent Management Center; and an internal file
system is supported, with the ability to remotely
backup and restore configuration files.

Cluster together up to 255 devices for easy
administration, with single IP management across
3Com switching lines—with mixed clusters of Switch
4210, 4200G, 4500, 4500G, 4800G, 5500 and 5500G
devices.

IPv6 management is also supported; there is no need
to replace the switch when upgrading to the latest
Internet Protocol standard.

REDUNDANT POWER SYSTEM SUPPORT

The two 3Com Switch 4210 PWR 26-Port model
supports a redundant power system (RPS) connection.

For this model, the RPS unit delivers redundant power
to switches so there is continued operation should the
switch unit power supply fail. This allows for
continuous operation of advanced Enterprise
networks, particularly important for converged
networks running IP phones on the network.

3Com H3C RPS Systems

3Com switches are compatible with 3Com H3C®RPS
s

olutions. These are enterprise-class power
redundancy systems that work with many 3Com
fixed-configuration switches. 3Com Corporation
manufactures networking equipment under the H3C
brand for sale into many markets.

The H3C RPS 1000 is 1U high and provides multiple
power output connections to support multiple switch
units at the same time. Two power rectifiers can be
installed for 1+1 load sharing and power redundancy.
It supports switches with -54V RPS connections, and
delivers sufficient power to fully provision all PoE
ports of a switch with full power redundancy.

PROVEN OPERATING SYSTEM

The 3Com Operating System employed in the Switch
4210 is the same powerful software used in the 3Com
Switch 8800 and Switch 7700 modular switches, the
Switch 5500 and 4500 stackables, and 3Com
enterprise routers. This consolidates administration
over the entire switching infrastructure and provides
edge-to-core visibility and control when using 3Com
management applications such as 3Com Enterprise
Management Suite, 3Com Intelligent Management
Center and 3Com Network Director.

WARRANTY AND SERVICES

3Com gives a Limited Lifetime Hardware Warranty on
the Switch 4210 Family, including the power supply
and fan.

Advance Hardware Replacement, with Next Business
Day shipment in most regions, and Limited Lifetime
software updates, is provided.

See www.3com.com/warranty for details.
