EX4400 Ethernet Switch
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. The Juniper Mist Cloud streamlines deploying and managing your campus fabric, while Mist AI simplifies operations and improves visibility into the performance of connected devices.

Features + Benefits
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.
Extend EVPN-VXLAN from the campus core to the distribution layer and access layer for simpler management and greater control and segmentation of endpoints. The EX4400 supports a Layer 3 IP-based underlay and EVPN-VLXAN overlay to interconnect multiple sites.
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.
Take segmentation to the next level by separating traffic within the same VLAN so IoT devices or users can traverse any port or switch within the network; maintain the same security policies without having to manually configure them each time.
Enables per-flow level analytics, so you can monitor thousands of traffic flows per switch without impacting the CPU.
For example, in the case of a DDoS attack, when flow thresholds are breached, the attack can be quickly detected. You can implement automated workflows to triage problems, such as quarantining a port or examining the traffic.
PoE, PoE++, and Fast PoE
The EX4400 offers fast PoE which enables power to be provided to the endpoints even as the switch reboot
Supports the 802.3bt standard for PoE, supplying up to 90 watts per port for mobile devices, IoT, and 802.11AX/Wi-Fi 6 access points.
The Juniper Networks® EX4400 line of Ethernet switches offers a secure, cloud-ready portfolio of access switches ideal for enterprise branch, campus, and data center networks. The EX4400 switches combine the simplicity of the cloud, the power of Mist AI™, and a robust hardware foundation with best-in-class security and performance to deliver a differentiated approach to access switching in the cloud, mobile, and IoT era. With Juniper Mist™ Wired Assurance, the EX4400 can be effortlessly onboarded, configured, and managed from the cloud. This simplifies operations, improves visibility, and ensures a much better experience for connected devices
