The Enterasys N-Series modular Ethernet switching and routing product family offers proven performance, reliability, and versatility for use at any network tier. The Enterasys N-Series delivers granular visibility and control over users, services, and applications to meet the increasing demands of today’s businesses and a wide range of deployment scenarios.

Capable of being deployed as a premium edge access device, distribution layer aggregation switch, small/medium-sized network core, or data center server farm solution, the Enterasys N-Series provides customers the ability to quickly and cost-effectively add connectivity as needed. With the same high availability architecture, best-in-class Quality of Service (QoS) functionality, and built-in security of other Enterasys chassis-based switches, the Enterasys N-Series delivers feature-rich networking that drives down maintenance costs and simplifies management.

Enterasys N-Series switches are available in the following form factors:

  • Standalone for smaller wiring closets
  • 1-Slot chassis providing full Distributed Forwarding Engine (DFE) connectivity
  • 3-Slot offering over 200 ports of connectivity
  • 5-Slot optimized for PoE deployments while offering over 350 ports
  • 7-Slot offering over 500 ports of connectivity

All of the N-Series offerings leverage the Enterasys DFE architecture whereby the switching, routing, and management control functions are embedded in each module, delivering unsurpassed reliability, scalability, and fault tolerance. Customers can quickly and cost-effectively add connectivity as needed while scaling performance capacity with each new blade. The DFE high-availability architecture makes forwarding decisions, enforces security policies, and classifies/prioritizes traffic. DFEs ensure the highest Quality of Service (QoS) for critical applications such as voice even during periods of over-subscription – while proactively preventing Denial of Service (DoS) attacks.

Unlike competing solutions, the N-Series implements a granular, flow-based architecture to intelligently manage individual user and application conversations-not just ports or VLANs. Policy rules combined with deep packet inspection can intelligently sense and automatically respond to security threats while improving reliability and quality of the user experience. NetFlow data can be collected at wire-speed without sacrificing performance or requiring sampling techniques. The N-Series is also the only enterprise switch to support multi-user, multi-method authentication on every port – absolutely essential when you have phones, computers, printers, copiers, security cameras, and badge readers on the network. When security matters, there is no better choice than the Enterasys N-Series.
