3COM SWCH 4500 26PT
The 3Com Switch 4500 is a high performance, managed 10/100 switch with advanced features, perfect for cost-conscious medium-sized businesses and branch offices looking for secure LAN connectivity. Layer 2 switching along with Layer 3 RIP-based dynamic routing make the Switch 4500 for wiring closet workgroup connectivity and as the core for small-size enterprises. The Switch 4500 26-port features 24Ύ/100 ports and two dual-personality ports, operating either asΎ/100/1000 or SFP-based fiber. Up to eight switches can be stacked via built-in Gigabit Ethernet ports, allowing single-IP management and distributed links in a stack of up to 384 ports. QoS, auto-voice VLAN, and traffic management features help ensure essential applications get the appropriate priority for efficient utilization of network resources. Furthermore, this switch has enterprise-class security features including IEEE 802.1X network login, SSH/SSL encrypted device log-in, Access Control Lists and RADIUS Authenticated Device Access (RADA).
