Description

The Juniper EX4400 Ethernet Switch Series is a modern, high-performance family of cloud-ready access and distribution switches designed for enterprise campus, branch, and data center environments. Powered by Junos OS and tightly integrated with Juniper Mist AI (Wired Assurance), the EX4400 delivers simplified operations, deep visibility, and AI-driven automation for next-generation networks.

Available in multiple configurations—including 1 GbE access (24/48-port), multigigabit (1/2.5/5/10 GbE), and 10 GbE SFP+ distribution models—the EX4400 provides flexible deployment options with uplinks supporting 10/25 GbE and optional 100 GbE via expansion modules. The platform supports Virtual Chassis technology, allowing up to 10 switches to operate as a single logical device, significantly simplifying network management and scaling.

With up to 3600W PoE budget (PoE++), support for Wi-Fi 6/6E/7 access points, IoT devices, and high-power endpoints, the EX4400 is well suited for modern smart buildings and campus deployments. Advanced features such as EVPN-VXLAN, MACsec AES-256 encryption, and streaming telemetry ensure secure, scalable, and highly visible network operations. The switches deliver up to ~1080 Gbps throughput (model dependent) and include redundant power supplies and fans for high availability.
