Ethernet Routing Switch 4000 Series The Ethernet Routing Switch 4000 Series is designed for enterprise wiring closets and other network edge deployments. This stackable chassis system delivers high performance, secure, and resilient Ethernet switching connectivity. Choose from a range of models that support 10/100 and 10/100/1000 switching and routing, PoE, PoE+, and 10 GbE uplink options. Features: Best-in-class stackable chassis implementation Pioneered by Avaya more than 12 years ago, our stacking technology delivers three to five times more virtual backplane capacity than leading competitive solutions according to a 2011 Miercom report. In addition, these switches support unit hot swapping without disrupting traffic. Superior energy efficiency The Ethernet Routing Switch 4000 Series products deliver between 20% to 50% more energy efficiency than leading competitive offerings according to a 2011 Miercom report. Avaya switches have been shown in some cases to utilize less power at 100% load capacity than competitive offerings when idle. Our easy-to-use energy management solution helps dim power consumption by an additional 25% during off peak hours. Improved collaboration Our Ethernet switches offer a suite of features to help ensure that your network is ready to support new collaboration applications and technologies. These features include support for sophisticated QoS, PoE/PoE+, and plug-and-play capabilities for IP phones. Support for next-generation edge requirements Our Ethernet Routing Switch 4800 models deliver future-ready support for advanced Avaya technologies such as network virtualization and wireless integration at the campus edge. 4548GT-PWR A flexible, high-density, convergence-centric variation of the 4548GT, this switch is ideal for typical enterprise wiring closet deployments where there is a full convergence requirement. It offers 48 ports of 10/100/1000 with 802.3af Power-over-Ethernet, including four combo Gigabit Ethernet ports.
