Features & Benefits Affordable, Managed Gigabit Switching with Flexible Uplinks The "smart" voice-ready 3Com® Baseline Plus Switch 2952 is a web-managed Gigabit switch with extensive layer 2 functionality and layer 3 static routes. It offers 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 QoS), this switch is the most cost-effective way to provide a converged network. Layer 2 Switching with Advanced Features The Baseline Plus Switch 2952 has forty-eight 10/100/1000 Mbps ports and four 1000 Mbps SFP ports (fiber) to connect to high-performance computers, servers, or core network backbones. This "smart" switch has the features that help build a voice ready network, with support for auto-voice VLAN, LLDP, SNMP-based management, IGMP snooping, and IEEE 802.1X and advanced Access Control Lists (ACLs) for strengthening security. The switch provides non-blocking performance— all 52 ports perform at wirespeed which helps to eliminate network traffic bottlenecks. LACP link aggregation (IEEE 802.3ad) allows ports to be automatically grouped together to form an ultra-high-bandwidth connection that greatly expands bandwidth capacity to the network backbone. The Baseline Plus Switch 2952 also supports Spanning Tree, Rapid Spanning Tree and Multiple 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. Enhanced Intuituve Management Options For networks that require more control, the switch web management interface provides an intuitive, menu driven process for even novice users to quickly and confidently configure the switch during initial setup and manage it during normal operation. Graphical switch and port views provide a clear understanding of switch status and configuration. In addition, the web interface features individual port-traffic monitoring (port mirroring) and MAC address port mapping tables. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface further simplifying network installation. With single IP management, up to 32 devices of the same family (3CRBSGxxx models) can be managed from one IP address via the IRF Lite functionalit. This Baseline Plus Switch is also supported by IMC (Intelligent Managent Center), 3Com Network Supervisor (3NS) and 3Com Network Director (3ND) management software. IMC can be used to map the network topology, indicating what devices are connected, and on what ports. Switch management and software upgrades can be easily done. Other SNMP-based management tools may also be used. The Switch family also supports a compact Command Line Interface (CLI) that is accessed via the front panel console port. Using the CLI, initial switch setup options can be quickly configured. Web-managed Layer 2 Gigabit Ethernet switch with 32 static routes Forty-eight 10/100/1000 ports and four Gigabit SFP ports; front-panel console port for CLI management Single IP management of up to 32 devices of the Baseline Plus 2900 family (3CRBSGxxx models) Operational out of the box with default settings or, if more control desired, the switch interface allows even novice users to quickly and confidently configure the switch VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth With LACP link aggregation, automatically group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks IEEE 802.1X network access control provides standards-based security combined with local authentication MAC- and IP-based ACLs enable network traffic filtering and enhance network control Auto-voice VLAN automatically assigns Voice over IP (VoIP) traffic to a voice-dedicated VLAN, optimizing this delay-sensitive traffic Spanning Tree Protocol (STP/RSTP/MSTP) support improves network compatibility, scalability and availability Jumbo Frame support for reduced network load IGMP snooping and multicast filtering optimizes network performance Switch can be managed with SNMP-compatible software like 3Com IMC, Network Supervisor and Network Director Product Specifications Download: the data sheet for complete specifications Ports: 52 ports total- 48 autosensing 10/100/1000 Mbps ports and 4 1000 Mbps SFP ports Performance: 104 Gbps, max.; wirespeed performance across ports Layer 2 switching: full-rate nonblocking on all ports, full-/half-duplex autonegotiation, flow control, IEEE 802.1Q VLAN support, IEEE 802.1p traffic prioritization, IGMP snooping; more Layer 3: 32 static routes Convergence: 4 hardware queues per port; traffic prioritization at Layer 2 (802.1p) and at Layer 3 (TOS with DSCP); auto-VLAN assignment for voice traffic; more Security: IEEE 802.1X network login; advanced ACLs Switch management: Web-based configuration; single IP management via IRF lite with models of the same family (3CRBSGxxx); 3Com IMC, Network Supervisor and etwork Director, other SNMP management tools; limited CLI using console port Dimensions: height 4.4 cm (1.7 in or 1 RU); width 44.0 cm (17.3 in); depth 26 cm (10.2 in) Weight: 5 kg (11.2 lb) More specifications: the data sheet for complete specifications Package Contents switch unit power cord self-adhesive rubber pads console cable rack-mount kit product CD warranty and safety information flyer

A user-friendly web browser lets even network novices easily set up and maintain a network. Wirespeed, non-blocking Layer 2 throughput and a switching capacity of up to 32 Gbps can handle the most bandwidth-intensive applications. Gigabit ports can be used for connections to high-performance computers, as well as high-demand servers. Class of service (CoS) traffic prioritization makes sure real-time applications run effectively and enables the switch to operate in larger networks. Any of the available ports can be trunked, or aggregated, to create an ultra-high bandwidth pipe to the network core. Copper and SFP-based fiber connections can be mixed together for versatile operation. VLAN support allows administrators to segment their network and divide available bandwidth, while traffic monitoring helps keep the network running at optimum performance even during busy traffic periods. A new Cable Diagnostic Tool is available in this switch allowing users to troubleshoot cabling problems via the Switch web-management interface. Using the straight forward menu based web GUI, the switch performs basic connectivity tests on the cables connected to the switch and helps to identify problems quicker. The switch also promotes "ease of use/plug and play" installation, operating straight out of the box, so it's up and running in minutes. With features like auto MDI/MDIX and autosensing ports, the small business switch eliminates the most common cabling errors and simplifies installation, as well as detecting and adjusting the speed of connected devices to optimize network performance. Small business configurations can vary, so the 3Com Baseline Switch 2816-SFP Plus is designed to operate as a free-standing or rack-mounted unit included mounting kit.
