Premium Stackable Chassis for the Network Edge

The Ethernet Routing Switch 5000 Series leverage the latest advances in network switching architecture design to maximize hardware performance and software capability. The ERS 5900 models represent a clear evolutionary step for the ERS 5000 Series, particularly in terms of value and future-ready flexibility, and have been optimized for the Enabled Edge role.  The ERS 5900s are an important part of this strategy, integrating Fabric Connect capabilities into a form-factor that is cost-effective, flexible, and reliable.

Supporting modern Enterprise applications requires a flexible and highly reliable infrastructure, and the ERS 5900 products deliver against this challenge. These are highly strategic products, fit-for-purpose for conventional Routed IP connectivity requirements and future-ready for the evolving and emerging software-defined needs of tomorrow. Boasting equal competency for both IP- and Fabric-based networking give businesses the flexibility to satisfy all common deployment scenarios, with the added advantage of an easy transitioning between the two.

The ERS 5900 products are purpose-built to support the demands of today’s dynamic Wiring Closet with high-density, full-featured Gigabit Ethernet.  The ERS 5900 products can be deployed standalone, or configured as a Stackable Chassis system of up to eight units/416 ports, supported by up to 672Gbps of virtual backplane bandwidth.

  • Deliver highly-available Ethernet connectivity for delay-sensitive and business-critical data and voice applications. Provide an effective solution for challenging environments with advanced Layer 3 routing services.
  • Add the ERS 5000 Series in the Wiring Closet for a ready path to network convergence with PoE+/UPoE, granular QoS, and 10 Gigabit uplinks.
  • Connect servers across racks and increase application performance using the ERS 5000 Series as 1 Gigabit Top-of-Rack option.


  • Non-blocking, wire-speed switching architecture
  • Integrated design that is optimized for low latency and high Quality-of- Service (including QoS-aware Stackable Chassis interfaces)

Innovative, Versatile, Highly Scalable Stacking Adds Capacity and Performance

Challenging deployments are easily facilitated by a hardware platform that incorporates wire-speed performance, fully integrated and high-output PoE, plug-and-play port scalability, and high-availability power and cooling.

Stack up to eight routing Switches to extend wire-speed performance and enhanced network availability. Connected together, ERS 5000 Series devices deliver 84Gbps of virtual backplane per Switch, and a total bandwidth of up to 672Gbps across the eight Switches.

Simplify your network by consolidating voice, video, and data on a single infrastructure. The ERS 5000 Series supports powering network devices, plug and play technologies, advanced QoS, and MACsec-ready capabilities to facilitate the deployment of communications, collaboration, and engagement solutions.

  • Improve application responsiveness: Wire-speed performance coupled with industry leading QoS-aware stack virtualization enhances traffic flows and optimizes applications.
  • Versatile deployment options: Available in models supporting 10/100/1000 connectivity, 10 Gigabit uplinks, and Layer 3 Routing, the ERS 5000 Series can flexibly address a range of advanced enterprise needs.
  • Lower your Total Cost of Ownership: As a price-per-port leader for resilient, high-performance Gigabit Ethernet, the ERS 5000 Series keeps TCO low.
