The Juniper Networks EX4300 line of Ethernet switches delivers the performance and scale required for both campus and data center Gigabit Ethernet (GbE) access switch deployments.Combined with Juniper’s market leading Virtual Chassis technology, the EX4300 scales up to 10 members, delivering the high availability and plug-and-play scale that businesses demand. Combining compact, pay-as-you-grow economics and low power and cooling with the performance, availability, and port densities of chassis-based platforms, the EX4300 with Virtual Chassis technology enables businesses to deploy with speed and agility to increase revenue and improve productivity.
The Juniper Networks EX4300 line of Ethernet switches with Virtual Chassis technology combines the carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center, campus and branch office environments.

The fixed-configuration EX4300 switches include a number of high availability features typically associated with chassis-based solutions, including the following:

  • Hot-swappable fans
  • Modular Juniper Networks Junos operating system (consistent with chassis systems)
  • Dual Routing Engines with graceful Routing Engine switchover (GRES)
  • Single management interface
  • Easy, centralized software upgrades
  • Scalability from 24 to 480 10/100/1000BASE-T ports and 24 to 240 100/1000/2500/5000/10000BASE-T ports, with up to 40 10GbE uplinks and 40 40GbE uplinks (up to 40 10GbE uplinks, 20 40GbE uplinks, or 20 100GbE uplinks on multigigabit models, in addition to four dedicated 40 Gbps Virtual Chassis ports per switch)
