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

The “smart” voice-ready 3Com® Baseline Switch 2250 Plus is a webmanaged Layer 2 10/100 Ethernet switch that delivers enterprise-class features, customized and priced for small- and mid-sized organizations. With an easy-to-use switch interface and advanced features (VLANs, IEEE 802.1X authentication and Rapid Spanning Tree), forty-eight 10/100 and two dual-purpose Gigabit ports, the Baseline Switch 2250 Plus is the most cost-effective way to provide a converged network.

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 or SNMP management software. SMART BROWSER-BASED USER INTERFACE For networks that require more control, the switch management interface allows even novice users to quickly and confidently configure the switch during initial setup or normal operation. In addition, the web interface features individual port-traffic monitoring (port mirroring) and a unique, quick-glance switch status review. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface further simplifying network installation.

THREE YEAR HARDWARE WARRANTY This switch comes with a Three Year Limited Hardware Warranty. Also provided is Advanced Hardware Replacement, with next business day shipment available in most regions. SERVICE 3Com products are backed by 3Com Global Services and authorized partners with demonstrated expertise in network assessment, implementation and maintenance. Ask about which 3Com Network Health Check, installation services and maintenance service packages are available in your area.

Feature Traffic prioritization and auto-voice VLAN Description Traffic prioritization, using IEEE 802.1p Quality of Service (QoS), and automatic assignment of VoIP traffic to dedicated VLANs help ensure that critical time-sensitive traffic gets the priority needed for quality communications. Take advantage of flexible, configurable and powerful switching that costs not much more than an unmanaged switch. Daisychain multiple units together via the built-in copper Gigabit uplink ports or connect to a network backbone via SFP-based fiber modules. Easy-to-use user interface allows even the most novice users to configure the switch during initial setup and monitor it during normal operation. 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. Group together any number of ports to form an ultra-high-bandwidth connection to the network backbone; help prevent traffic bottlenecks. Administrators can examine suspect data streams received on any port by mirroring the data stream to a monitoring port. Provides standards-based security with EAP-MD5 protocol. Switch can be managed with SNMP-compatible tools. Improves network compatibility, scalability and availability. Multicast filtering optimizes network performance, instead of flooding traffic to all ports. Remotely detect cable issues using a browser-based tool. Silent operation whether used in a rack or desktop situation.
