Enterprise-class stackable-switch for edge applications; meets the demanding needs of secure, converged networks. The 3Com® Switch 4500 26-Port stackable Ethernet switch features rich Layer 2 switching and dynamic Layer 3 routing in a cost-effective, high performance platform. With robust security, extensive management, traffic prioritization and quality of service features, the Switch 4500 26-Port capably handles emerging business applications. Up to eight switches can be stacked via Gigabit Ethernet ports, allowing single-IP management for an entire stack. 24 10/100 ports with industry standard Power over Ethernet and two dual-personality Gigabit ports allow the Switch 4500 to provide secure, dependable LAN connectivity and support next-generation voice applications for small to medium enterprise and branch office networks. - Security: 802.1X network access control combined with RADIUS authentication ensures secure access to resources. Additionally, RADIUS Authenticated Device Access (RADA) enables authentication of attached devices via MAC address. Port-based Access Control Lists (ACLs) effectively enable usage policies at each point of access to the network via the switch. Secure Shell (SSHv2) and SNMPv3 support ensure secure management access to switches via authentication and encryption of management traffic. - Dynamic Voice over IP: Unique Voice VLAN feature detects the presence of IP phones and dynamically assigns switch ports to the Voice VLAN, enabling automated configuration and prioritization of VoIP traffic. This powerful feature minimizes cost and complexity associated with adding or moving IP phones. - Performance: Aggregate switching capacity up to 8.8 Gbps. Dual Gigabit uplinks on each switch unit enable high-speed connections to the network backbone or locally attached servers. - Prioritization and Bandwidth Management: Eight priority queues per port enable 802.1p Class of Service / Quality of Service (CoS/QoS). Bandwidth rate limiting and protocol filtering capabilities allow the Switch 4500 family to enforce controls on each port for efficient use of network resources and prioritization of "business-critical" or "time-sensitive" applications, including Voice over IP (VoIP). - Power over Ethernet (PoE): Provide inline power to attached devices via industry-standard 802.3af Power over Ethernet (PoE). The internal power supply provides a power budget of 300 Watts, which is dynamically allocated to PoE ports. Supplemental power can be provided by an optional external DC power system, supplying up to 15.4 Watts of power to all PoE ports in a switch or stack. - Flexibility and Scalability: Each Gigabit port offers a choice of copper or fiber media: 1000Base-T (via RJ45) or 1000Base-X (via optional "SFP" Small Form Factor Pluggable transceiver modules). Stacking capability allows up to 8 units to be combined in a single managed stack, scaling up to as many as 384 10/100 ports. A comprehensive set of switching features, including multicast filtering and Rapid Spanning Tree Protocol support, act to further improve scalability and availability of network resources. - Management and Control: Powered by the 3Com Operating System, the same proven software featured in 3Com premium enterprise switches - including the Switch 5500, Switch 7700, and Switch 8800 families. Network configuration and control features are accessible via command line interface (CLI), or by using SNMP management software such as 3Com Enterprise Management Suite (EMS) and 3Com Network Director. - Ease of Use: Dynamic routing with RIP (Routing Information Protocol) allows automatic updating of Layer 3 network topologies. Speed and duplex mode on all ports are negotiated automatically, preventing the possibility for improper configuration. Switches detect and adjust to cross-over or straight through cable connections via "Auto MDI/MDIX" feature, eliminating the need for different cables to interconnect network devices.
