3Com®Baseline Switch 2250 Plus

Enterprise-class,
Layer 2 10/100 switch
for small and medium
businesses, with
advanced features for
network control and
flexibility

OVERVIEW

The “smart” 3Com®Baseline Switch 2250 Plus is a web-managed Layer
2 10/100 Ethernet switch that delivers enterprise-class features, cus-

omized and priced for small- and mid-sized organizations. With an

t
easy-to-use switch interface and advanced features (VLANs, IEEE

802.1X authentication and Rapid Spanning Tree), forty-eight 10/100
ports and two dual-purpose Gigabit ports, the Baseline Switch 2250
Plus is the most cost-effective way to provide a managed network.

KEY BENEFITS

LAYER 2 SWITCHING WITH ADVANCED FEATURES

The Baseline Switch 2250 Plus has forty-eight 10/100 ports and two
dual-purpose Gigabit ports (copper or SFP-based fiber) to connect to
high-performance computers, servers, or core network backbones.

The switch provides non-blocking performance—all ports perform at
wirespeed which helps to eliminate network traffic bottlenecks. Manual
link aggregation allows ports to be grouped together to form an ultra­high-bandwidth connection that greatly expands bandwidth capacity to
the network backbone.

This “smart” switch has the features that help build a voice ready
network, with support for auto-voice VLAN, SNMP-based management,
IGMP snooping and query and IEEE 802.1X for strengthening security.

The Baseline Switch 2250 Plus also supports Spanning Tree and Rapid
Spanning Tree, traffic prioritization, priority queuing and VLANs.
These switching features ensure optimal use of available bandwidth as
traffic flow is directed according to the needs of the business.

NO SWITCH SETUP REQUIRED

This Baseline Plus switch is operational straight out-of-the-box; as long
as default settings are acceptable, there is no need to configure the
switch. If desired, the switch can be configured using a web browser
