ADVANCED FEATURES:

AI-Driven Wired Networking with Juniper Mist AI:

The EX4400-24P is tightly integrated with the Juniper Mist AI cloud platform, enabling IT teams to adopt an AI-driven operational model. With continuous monitoring, anomaly detection, and proactive issue resolution, the switch ensures consistent performance while reducing manual troubleshooting. By shifting from reactive support to predictive operations, enterprises benefit from lower downtime, faster resolutions, and an improved end-user experience.

Enterprise-Grade PoE+ Capability:

The EX4400-24P supports IEEE 802.3at PoE+ standards, delivering up to 30 W of power per port, with a total PoE budget of up to 505 W. This ensures reliable powering of critical devices such as Wi-Fi 6 access points, VoIP phones, IP surveillance cameras, and IoT sensors. Its power flexibility makes it a cost-effective choice for modern enterprise access networks while maintaining readiness for evolving device requirements.

Integrated Network Security and Segmentation:

Security is built directly into the EX4400-24P architecture. With MACsec AES-256 encryption, sensitive data remains secure across the wired network. Advanced features such as Dynamic ARP Inspection (DAI), DHCP snooping, and IP Source Guard help safeguard the network against spoofing and unauthorised access. Combined with scalable, policy-driven segmentation, IT administrators can isolate traffic for different user groups or IoT devices, maintaining compliance and reducing attack surfaces.

Scalable Virtual Chassis Technology:

The EX4400-24P supports Juniper’s proven Virtual Chassis technology, which allows up to 10 interconnected switches to be managed as a single device. This simplifies network operations by centralising management, configuration, and software updates. With seamless failover and unified control, enterprises achieve high resiliency while reducing operational complexity in large-scale deployments.

High Availability and Flexible Deployment:

Built for demanding enterprise environments, the EX4400-24P includes redundant, hot-swappable power supplies and field-replaceable fans, ensuring continuous operation and simplified maintenance. Available airflow options (front-to-back or back-to-front) enable deployment in diverse data centre and campus environments. Its compact 1U form factor makes it suitable for both access-layer and aggregation use cases.

Cloud-Ready Automation and API Integration:

With extensive automation support including Zero-Touch Provisioning (ZTP), NETCONF, Ansible, and Python scripting, the EX4400-24P accelerates deployment and streamlines operations. Its REST APIs and streaming telemetry provide deep visibility into network behaviour and allow integration with DevOps toolchains, enabling agile, cloud-like management of wired infrastructure.

High-Performance Switching Architecture:

The EX4400-24P is equipped with a robust 880 Gbps switching capacity and a forwarding rate of 654 Mpps, ensuring wire-speed performance across all ports. It supports up to 64,000 MAC addresses and jumbo frames up to 9,600 bytes, optimising performance for high-bandwidth applications including video conferencing, IP surveillance, and virtual desktop environments. This non-blocking architecture guarantees consistent throughput even under heavy workloads.
