Higher Density Gigabit Ethernet Switch With Virtual Chassis Technology for Copper-Based Networks

Sorry, this item is not available anymore for purchase online. Please see our recommended replacement product.

The PowerConnect™ J-EX4200-48T Ethernet switch for enterprise networks combines the pay-as-you-grow convenience and low-power and cooling features of stackable switches with the performance, availability, port densities and operational ease of chassis-based platforms. The J-EX4200-48T switch delivers 48 ports of Fast Ethernet and Gigabit Ethernet support, of which eight ports can be powered by the network (PoE), thereby reducing power needs for the switch.

  • Ethernet switch offers high availability, high performance and a single point of management in a compact, power-efficient 1U framework.
  • Virtual chassis technology enables connecting up to 10 switches as a single logical device supporting up to 480 server access ports, lowering management and administrative overhead.
  • Junos® network OS with a consistent feature set helps shorten the learning curve and lower operational expenses.

PowerConnect J-EX4200-48T Ethernet Switch

Innovative Architecture

The PowerConnect J-EX4200-48T Ethernet switches feature complete enterprise Layer 2 and Layer 3 switching capabilities to satisfy your high-density access and Gigabit Ethernet (GbE) aggregation requirements.
  • Optional GbE and 10 GbE uplink modules enable high-speed connectivity to aggregation or core-layer switches.
  • Internal redundant, hot-swappable power supplies and a field-replaceable fan tray with redundant blowers help ensure maximum uptime.
  • Eight power over Ethernet (PoE) ports deliver a full 15.4 watts of Class 3 PoE to support IP-enabled telephones, video cameras and wireless LAN access points in converged networks.
  • A purpose-built, packet-forwarding-engine application-specific integrated circuit (ASIC) consistently delivers wire-rate forwarding, even with all control-plane features enabled.
PowerConnect J-EX4200-48T: Virtual Chassis technology

Virtual Chassis Technology

In a virtual chassis configuration, all switches can be monitored and managed as a single device, which enables administrators to improve network efficiency by separating physical topology from logical end-point groupings.

Up to 10 PowerConnect J-EX4200-48T switches can be connected to create a single logical device supporting up to 480 10/100/1000BASE-T ports plus an additional 20 GbE or ten 10 GbE uplink ports, which helps:
  • Ease configuration and management
  • Reduce operational costs
  • Simplify cabling
  • Lower cooling costs
  • Conserve data center floor space
Servers attached to the top-of-rack devices are connected by a single, high-bandwidth, low-latency switch and do not rely on an aggregation switch for server-to-server communications. What's more, different models, such as the PowerConnect J-EX4200-24T and PowerConnect J-EX4200-24F, can be mixed to provide a variety of port and density options.

A single virtual switch can also be created using the GbE or 10 GbE uplink ports to extend the virtual chassis configuration across long distances, spanning different wiring closets, floors or even buildings.

Junos Operating System

The PowerConnect J-EX4200-48T Ethernet switch runs on the Junos OS, which is commonly used across all J-Series products, as well as many of the world’s largest and most complex networks.
  • Highly disciplined, the Junos OS development process uses a single source code, follows a single quarterly release train and employs a highly available modular architecture that prevents isolated failures from bringing an entire system down.
  • Fully regression-tested, each new release is a true superset of the previous version. Therefore, whenever Junos-powered products are updated, all existing capabilities will be maintained and operate in the same way.
  • Session-based forwarding combines the session state information of a traditional firewall and the next-hop forwarding of a classic router into a single operation, helping to improve throughput and lower latency for session traffic when compared to classic
Leveraging a common version of the Junos OS across the switch families ensures consistency throughout the infrastructure and reduces the learning curve.
