OVERVIEW
The 3Com
®
Switch 4210 is a family of Layer 2 entry-
level 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.

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.

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
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.
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
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 auto-
MDI/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.
