ADVANCED FEATURES:

High-Performance Architecture:

The Juniper EX4650-48Y is a next-generation enterprise-class switch designed for modern campus aggregation and data centre spine/leaf architectures. With its compact 1U form factor, it combines high port density, advanced security, automation, and open programmability to deliver unmatched performance and agility. Offering 48 × 1/10/25GbE SFP28 ports and 8 × 40/100GbE QSFP28 uplinks, the EX4650 delivers a total switching capacity of 2 Tbps with a forwarding rate of 1,440 Mpps, ensuring wire-speed, non-blocking performance with consistently low latency.

Fabric and Virtualisation Capabilities:

The platform supports Virtual Chassis and Virtual Chassis Fabric technology, enabling up to 10 interconnected EX4650 units to operate as a single logical switch for simplified management and reduced configuration overhead. With full support for EVPN-VXLAN overlays, the switch is ideal for scalable Layer 2 and Layer 3 extensions across data centres and campus cores, offering seamless application mobility and multi-cloud connectivity while reducing reliance on legacy protocols.

Integrated Security:

Security is built into the architecture, with line-rate MACsec AES-256 encryption available on all 10/25/40/100GbE interfaces. This ensures strong protection for sensitive traffic in industries such as finance, healthcare, and government. Integration with Juniper’s Advanced Threat Prevention (ATP) and Mist AI further enhances security posture by enabling automated policy enforcement and Zero Trust networking.

Resiliency and High Availability:

The EX4650 is designed for high availability with dual hot-swappable power supplies (available in AC and DC variants) and field-replaceable fans with airflow options for both front-to-back and back-to-front cooling. Advanced resiliency features such as Graceful Routing Engine Switchover (GRES), Nonstop Bridging (NSB), and Nonstop Routing (NSR) ensure uninterrupted service during upgrades and failures, delivering carrier-class reliability in enterprise and service provider environments.

Automation and Cloud Integration:

For automation and operational efficiency, the EX4650 integrates with Juniper Mist Cloud to provide AI-powered analytics, predictive insights, and proactive troubleshooting. Open programmability is supported through APIs such as NETCONF, REST, gRPC, and automation frameworks including Python and Ansible, enabling intent-based networking and DevOps-driven deployments.

Flexible Deployment Options:

The switch offers deployment flexibility across multiple roles, including as a campus aggregation switch, top-of-rack device, or a high-performance spine/leaf node in EVPN-VXLAN fabrics. Its support for up to 288,000 MAC addresses, 4,096 VLANs, and extensive IPv4/IPv6 routing tables provides investment protection and scalability to meet future networking demands. Backward compatibility with 10GbE and 40GbE, combined with native support for 25GbE and 100GbE, ensures smooth transitions and long-term adaptability in evolving IT environments.

Future-Ready Networking:

In essence, the EX4650-48Y is more than a high-performance switch; it is a scalable, secure, and cloud-ready platform designed to address the requirements of enterprise campuses, mission-critical data centres, and hybrid multi-cloud environments.
