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.
Redundant power supplies
The EX4300 line of Ethernet switches supports internal redundant, load-sharing, hot-swappable, and field-replaceable AC and DC power supplies to maintain uninterrupted operations. Thanks to its compact footprint, the EX4300 requires significantly less power than chassis-based switches delivering equivalent port densities.
The EX4300 includes hot-swappable fans, providing sufficient cooling even if one of the fans were to fail.
Non-Stop Bridging (NSB) and Non-Stop Routing (NSR)
NSB and NSR on the EX4300 ensure control plane protocols, states and tables are synchronized between Master and Standby REs to prevent protocol flaps or convergence issues following a Routing Engine failover.
Redundant trunk group (RTG)
To avoid the complexities of Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX4300 employs redundant trunk groups to provide the necessary port redundancy and simplify switch configuration.
Cross-member link aggregation
Cross-member link aggregation allows redundant link aggregation connections between devices in a single Virtual Chassis configuration, providing an additional level of reliability and availability.
The EX4300 leverages a purpose-built packet forwarding engine ASIC, the EX-PFE, which integrates much of the same intellectual property used in Juniper Networks carrier-class routers. As a result, the EX4300 delivers the same predictable, scalable functionality found in the world's largest networks.
IPv4 and IPv6 routing support
IPv4 and IPv6 Layer 3 routing (OSPF and BGP) is available with an enhanced license, enabling highly resilient networks.
