Affordable, Managed Gigabit PoE Switching with Flexible Uplinks\nThe "smart" voice-ready 3Com® Baseline Plus Switch 2928 PWR is a web-managed Gigabit Power over Ethernet (PoE) 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.\n\nWith 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.\n\nPower over Ethernet\nThe Baseline Plus Switch 2928 PWR provides inline power to attached devices— access points, Voice over IP (VoIP) phones, IP security cameras, etc.— via industry-standard IEEE 802.3af Power over Ethernet over a single Ethernet cable, resulting in significant deployment cost savings.\n\nLayer 2 Switching with Advanced Features\nThe Baseline Plus Switch 2928 PWR has twenty-four 10/100/1000 Mbps ports and four 1000 Mbps SFP ports (fiber) to connect to high-performance computers, servers, or core network backbones.\nThis "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.\nThe switch provides non-blocking performance— all 28 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.\nThe Baseline Plus Switch 2928 PWR 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.\n\nNo Switch Setup Required\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.\n\nEnhanced Intuituve Management Options\nFor 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.\nIn 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.\nWith 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.\nThis Baseline Plus Switch is also supported by IMC (Intelligent Managent Center), 3Com Network Supervisor (3NS) and 3Com Network Director (3ND) management software.\nIMC 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.\nThe 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.\n\n- Web-managed Layer 2 Gigabit Ethernet switch with 32 static routes;\n- Twenty-four 10/100/1000 PoE ports and four Gigabit SFP ports; front-panel console port for CLI management;\n- PoE provides power for IP phones, wireless LAN access points, 3Com Intellijacks and other compliant devices over the same cable used for data;\n- Single IP management of up to 32 devices of the Baseline Plus 2900 family (3CRBSGxxx models);\n- 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;\n- VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth;\n- 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;\n- IEEE 802.1X network access control provides standards-based security combined with local authentication;\n- MAC- and IP-based ACLs enable network traffic filtering and enhance network control;\n- Auto-voice VLAN automatically assigns Voice over IP (VoIP) traffic to a voice-dedicated VLAN, optimizing this delay-sensitive traffic;\n- Spanning Tree Protocol (STP/RSTP/MSTP) support improves network compatibility, scalability and availability;\n- Jumbo Frame support for reduced network load;\n- IGMP snooping and multicast filtering optimizes network performance;\n- Switch can be managed with SNMP-compatible software like 3Com IMC, Network Supervisor and Network Director.
