Affordable, Web-managed 10/100 Ethernet Switching with Gigabit Uplinks\r\nThe "smart" 3Com? Baseline Switch 2250 Plus is a web-managed Layer 2 10/100 Ethernet switch. It offers enterprise-class features, customized and priced for small- and mid-sized organizations. With an easy-to-use interface and advanced features (VLANs, IEEE 802.1X authentication and Rapid Spanning Tree), this switch is a cost-effective way to provide a converged network.\r\n\r\nLayer 2 Switching with Advanced Features\r\nThe 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.\r\n\r\nThe 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 ultra-high-bandwidth connection that greatly expands bandwidth capacity to the network backbone.\r\n\r\nThis "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.\r\n\r\nThe 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.\r\n\r\nNo Switch Setup Required\r\nThis 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.\r\n\r\nSmart Browser-Based User Interface\r\nFor networks that require more control, the switch management interface? completely redesigned to enhance useability? allows even novice users to quickly and confidently configure the switch during initial setup or normal operation.\r\n\r\nIn 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.\r\n\r\n- Web-managed Layer 2 10/100 Ethernet switch\r\n- Forty-eight 10/100 ports and two dual-purpose Gigabit ports (copper or SFP-based fiber)\r\n- No need to configure the switch if default settings are acceptable\r\n- If more control desired, the switch interface allows even novice users to quickly and confidently configure the switch\r\n- Switch can be managed with SNMP-compatible software\r\n- VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth\r\n- Voice over IP (VoIP) traffic can be automatically assigned to a voice-dedicated VLAN, optimizing this delay-sensitive traffic\r\n- With manual link aggregation, group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks\r\n- IEEE 802.1X network access control provides standards-based security combined with local authentication\r\n- Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability\r\n- IGMP snooping and query and multicast filtering optimizes network performance\r\n- Easy-to-use browser based tools allow remote detection of cable issues
