The EX4400 Ethernet Switch is a cloud-ready, AI-powered access switching platform with advanced security for high-performance campus deployments. It’s differentiated by features such as Power over Ethernet (PoE, PoE++), MACsec AES-256, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, and flow-based telemetry.

As part of the underlying infrastructure for Juniper Mist Wired Assurance, the EX4400 is easy to onboard, configure, and manage. It uses Mist AI to simplify operations and improve visibility into the performance of connected devices.

• AI-Driven Switching
  Onboard (day 0), provision (day 1), and manage (day 2+) the EX4400 from the cloud with Juniper Mist Wired Assurance, using AI-powered automation and insights to deliver improved experiences for end users and connected devices. A color-coded LED display indicates cloud connectivity status. Streamline IT operations, reduce mean time to repair, and deliver a new generation of wired and wireless networks. The EX4400 provides rich streaming telemetry data for insights into switch health and wired service-level expectations (SLEs) for pre- and post-connection metrics.
• End-to-End Campus Fabric
  Scale with ease, build resiliency, and streamline management with Virtual Chassis and EVPN-VXLAN-based campus fabrics, which help to simplify configuring and maintaining multiple devices
• Microsegmentation
  Standards-based microsegmentation using group-based policies (GBP) leverages underlying VXLAN technology to provide agnostic endpoint access control for consistent security policies and granular control of application, business function, or user tags.
• Flow-Based Telemetry
  Enables per-flow level analytics, so you can monitor thousands of traffic flows per switch without impacting the CPU.
• PoE, PoE++, and Fast PoE
  The EX4400 offers fast PoE which enables power to be provided to the endpoints even as the switch reboot
