The Avaya Ethernet Routing Switch 4500 series is a stackable system providing high performance, convergence-ready, secure and resilient Ethernet switching connectivity. The Ethernet Routing Switch 4500 series is ideally suited for enterprise wiring closet and other network edge deployments.


The Ethernet Routing Switch 4500 series (ERS 4500) provides genuine resilient stacking, layer 2 switching and layer 3 routing, and convergence features. This enables the ERS 4500 series to deliver the scalability and resiliency required by application-driven enterprise networks while reducing total operational costs. Indeed, ERS 4500 model is up to 40% more energy efficient than competitive products, ensuring superior total cost of ownership.


This switch is designed to serve as a low-density option for the low-intensity enterprise wiring closet. It offers 26 concurrent network interfaces, with 26 ports of 10/100 Ethernet plus two gigabit uplink ports that are a combo configuration of 1000BASE-T/SFP.
