ADVANCED FEATURES:

JUNIPER MIST AI INTEGRATION:

The EX4400‑48P integrates seamlessly with Juniper Mist AI, providing AI-driven insights that continuously monitor network performance, detect anomalies, and proactively identify issues before they impact operations. This predictive intelligence helps IT teams move from reactive troubleshooting to proactive management, reducing downtime and improving user experiences across the enterprise network.

HIGH POE POWER BUDGET:

Supporting IEEE 802.3bt (PoE++) standards, the switch delivers up to 90 W per port, with a total PoE power budget of 2,200 W using dual AC power supplies. This enables powering next-generation Wi-Fi 6/6E access points, high-definition security cameras, smart building sensors, and other demanding IoT devices, ensuring uninterrupted operation for critical equipment.

VIRTUAL CHASSIS TECHNOLOGY:

The EX4400‑48P supports Virtual Chassis, allowing up to 10 switches to operate as a single logical unit. This simplifies management, unifies software upgrades, and provides seamless failover, creating a highly resilient and scalable network fabric.

ADVANCED SECURITY:

Security is built into the switch architecture with MACsec AES-256 encryption, Dynamic ARP Inspection, DHCP Snooping, and IP Source Guard. Combined with EVPN-VXLAN overlays, IT administrators can enforce granular segmentation and policy-driven access control to protect sensitive traffic and prevent unauthorized access.

AUTOMATION AND PROGRAMMABILITY:

The switch supports Zero-Touch Provisioning (ZTP), NETCONF, Python, and Ansible, enabling rapid deployment and integration with DevOps workflows. Real-time telemetry provides deep visibility into traffic patterns, device health, and network performance, supporting proactive capacity planning and operational efficiency.

HIGH-PERFORMANCE SWITCHING FABRIC:

With a switching capacity of 912 Gbps and a forwarding rate of 654 Mpps, the EX4400‑48P delivers non-blocking throughput for large-scale data flows such as video surveillance, virtual desktops, and high-speed wireless backhaul. Front-to-back airflow (AFO) and field-replaceable fans ensure optimal thermal performance in demanding environments.
