				3Com® SuperStack® 3 Switch 4400 Family Overview DISCONTINUED Product #: WEBBNC4400SYS

			Features & Benefits Advanced Enterprise-Class Workgroup Switching The 3Com® SuperStack® 3 Switch 4400 family offers high-performance, feature-rich 10/100 Ethernet LAN switching options that range from a fully featured high-density model to an attractively priced entry-level model that can be upgraded to the enhanced feature set. All five of this family's managed switches support hot-swappable resilient stacking, as well as Gigabit or Fast Ethernet uplinks via optional plug-in modules. One switch offers Power over Ethernet. 3Com SuperStack 3 Switch 4400 48-Port delivers high-density switching in an affordable platform. A massive 13.6 Gbps switching fabric enables forwarding up to 10.1 million packets per second (pps). Advanced QoS functionality and multilayer traffic classification permit prioritization of mission-critical applications and real-time traffic. 3Com SuperStack 3 Switch 4400 24-Port offers the same features as the 48-port model, with a forwarding rate of 6.6 pps. The SuperStack 3 Switch 4400 PWR combines Power over Ethernet technology (IEEE-802.3af) with the advanced features, simplicity, and style of the SuperStack 3 Switch 4400 24-Port. This design provides power and data over a single cable to any compliant device, including 3Com NBX phones, wireless LAN access points, and Network Jack products. 3Com SuperStack 3 Switch 4400 SE 24-Port provides Layer 2 switching in an economical platform that is software-upgradable to 3Com SuperStack 3 Switch 4400 24-Port functionality. Optional switching modules provide resilient high-speed connections such as Fast Ethernet, including 100BASE-LX (Ethernet in the First Mile), and Gigabit Ethernet copper or fiber links.
