3Com Baseline Switch 2250 Plus
Key Benefits
Overview
The “smart” 3Com®Baseline Switch 2250
Plus is the latest member in the family of
premium value Baseline Plus switches
that deliver enterprise-class solutions,
customized and priced for small and
mid-sized organizations.
The 3Com Baseline Switch 2250 Plus
provides forty-eight 10/100 ports and two
dual-purpose Gigabit ports to connect to
high-performance computers, high demand
servers, or core network backbones, either
using the built-in copper Gigabit uplink
ports or the SFP based slots for Gigabit
fiber connections. With a low entry cost,
the 3Com Baseline Switch 2250 Plus offers
advanced administration through a user-
friendly browser interface so that even
network novices can easily configure and
administer the network. QoS and VLAN
support allows greater scalability and
support for business-critical applications
such as customer relation management
(CRM), supply chain management (SCM)
and video conferencing. Ports can be
trunked, or aggregated, to create an ultra-
high bandwidth pipe to the network core.
Ethernet Switching
The 3Com Baseline Switch 2250 Plus is a
non-blocking Layer 2 switch—all ports
switch at wire speed—which helps to
eliminate network traffic bottlenecks.
Once more, Link aggregation via
IEEE802.3ad allows administrators to
group any number of copper or fiber ports
together to form an ultra-high bandwidth
pipe that greatly expands bandwidth
capacity to the network backbone. The
switch also supports VLANs, which
segment the network by grouping users
based on data or traffic exchange require-
ments. These switching features ensure
optimal use of available bandwidth as
traffic flow is directed according to the
needs of the business.
Intuitive web browser-based user
interface
The 3Com Baseline Switch 2250 Plus
provides an easy-to-use web-based inter-
face that allows even novice users to
quickly and confidently configure the
switch during initial setup or normal oper-
ation. The web interface makes it easy to
configure individual port speeds and
duplex configuration, VLANs, Link aggre-
gation, and traffic prioritization, as well as
keep an eye on network traffic and statis-
tics. These capabilities make the switch an
exceptional value.
An enterprise-class solution for Small-
to-Mid-sized businesses
The 3Com Baseline Switch 2250 Plus is
operational straight out of the box; as long
as basic settings are acceptable, there is no
need to configure the switch. For networks
that require more control, the user-friendly
web based interface provides easy-to-use
tools to design your network for optimal
use. All 3Com networking products go
through vigorous testing to ensure top
reliability. A proven reputation for quality
is backed by an industry-leading support
package with a Limited Lifetime Hardware
Warranty and Worldwide Next Business
Day Advance Hardware Replacement.

FEATURES BENEFITS
Outstanding value Take advantage of flexible, configurable and powerful switching that costs not much more than an
unmanaged switch.
Flexible Gigabit uplinks Choose to daisychain multiple units together via the built-in copper Gigabit uplink ports or connect to a
network backbone via SFP-based fiber modules.
Browser-based user interface for switch Extremely easy-to-use user interface allows even the most novice users to configure the switch during initial
configuration and administration setup or normal operation.
VLANs Segment the network by grouping users based on their data or traffic exchange requirements. This ensures
optimal use of available bandwidth as traffic flow is directed according to the needs of the business.
Link aggregation (trunking) Group together any number of copper or fiber ports to form an ultra-high bandwidth pipe connecting the
switch to a network backbone and prevent any traffic bottlenecks. The switch supports up to four trunks
and up to eight ports per trunk.
Traffic monitoring (port mirroring) Administrators can examine suspect data streams received on any port by mirroring the data stream to a
monitoring port.
Limited Lifetime Warranty and Offerring complete peace of mind.
