Intelligent Stacking for the Network Edge

The Ethernet Routing Switch 4000 Series are next-generation, high-performance, feature-rich Ethernet Switch platforms specifically optimized for the Wiring Closet demands of the mainstream Enterprise.  ERS 4000 Series products deliver the agility to perform equally in conventional IP and Ethernet Fabric-based networking solutions.

The ERS 4900 models leverage the latest advances in network switching architecture design to maximize hardware performance and software capability. These products represent a clear evolutionary step for the ERS 4000 Series, particularly in terms of value and future-ready flexibility, and have been optimized for the Enabled Edge role.

The new ERS 4900 products are an important part of this strategy, integrating Fabric Connect capabilities into a form-factor that is cost-effective, flexible, and reliable. ERS 4900s can be deployed standalone, or configured as a Stackable Chassis system of up to eight units/400 ports, supported by up to 416Gbps of virtual backplane bandwidth.

Supporting modern Enterprise applications requires a flexible and highly reliable infrastructure, and the ERS 4900 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.

  • Deliver high-performance, resilient Ethernet connectivity for Wiring Closet and Network Edge deployments. Featuring stacking technology with twice the virtual bandwidth of leading competitors, superior energy efficiency, and ease of operation, the ERS 4000 can address the most demanding converged edge requirements.
  • Consolidate voice, video, and data on a single infrastructure that supports PoE/PoE+, plug-and-play for IP Phones, and sophisticated QoS. These Ethernet Switches help ensure that your network is ready for advanced collaboration applications or technologies.
  • 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)
  • Feature-rich support for conventional VLAN, Private VLAN, Multi-Link Trunking, Spanning Tree technologies
  • Stackable Chassis technology supporting scalability up to 8 units/400 ports, and Auto-Unit Replacement for Software Image and Configuration

Convergence-Ready Switches for the Wiring Closet and Network Edge

Stackable Chassis technology on the ERS 4000 Series lets you start small and expand the network as needed. Stack up to eight Switches for enhanced network availability. You’ll have simplified management, and up to 384Gbps of virtual backplane capacity.

The ERS 4000 simplifies convergence and consolidation of voice, video, and data on a single infrastructure. This includes powering network devices, using plug and play to set up IP phones, and sophisticated QoS capabilities.

The ERS 4900 models support Fabric Connect. This lets Fabric-based services extend from the Data Center to the Network Edge, providing a consistent enterprise-wide virtual network that is more adaptive, reliable, and simpler to operate.

  • Smooth implementation: Our Stackable Chassis technology combines a non-blocking internal switching fabric with a high-speed backplane to deliver more than twice the virtual backplane capacity of leading competitors’ solutions. These Switches support unit hot swapping and auto-configuration that minimizes disruption to other switches and traffic.
  • Solid performance: Designed to keep the most demanding collaboration applications running optimally, the ERS 4000 Series supports both PoE and PoE+, sophisticated QoS, and plug and play for IP phones.
  • Superior energy efficiency: The ERS 4000 Switches are, on average, 36% more energy-efficient than competitive solutions. They support an Energy Saver technology that can dim power consumption for both the Switch and IP Phones by 25% during off-peak hours without losing telephony connectivity.
