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. 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.
