The 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. The Switch 4500 provides secure, dependable LAN connectivity for small to medium enterprise and branch office networks. This switch features Power over Ethernet capability.

The 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. 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. 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.
