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.
- Redundant power supplies: The EX4300 line of Ethernet switches supports internal redundant, load-sharing, hot-swappable, and field-replaceable 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 1GbE access switches offer both AC and DC options, while the EX4300 multigigabit switch supports only AC power supplies.
- Hot-swappable fans: The EX4300 includes hot-swappable fans, providing sufficient cooling even if one of the fans were to fail.
- Nonstop bridging and nonstop routing: NSB and NSR on the EX4300 ensure that control plane protocols, states, and tables are synchronized between primary 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.
- Carrier-class hardware: The EX4300 leverages a purpose-built packet forwarding engine ASIC, the EX-PFE, which integrates much of the same intellectual property used in Juniper’s 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) are available with an Enhanced license, enabling highly resilient networks.
