EX4400 Multigigabit Ethernet Switch
The EX4400 Multigigabit Ethernet Switch is an AI-powered, cloud-ready access switching platform with flow-based telemetry and advanced security for high-performance deployments in modern campus environments. The switch offers multigigabit speeds of 100M/1/2.5/5/10GbE and greater power (PoE, PoE++) for Wi-Fi 6 and 802.11ac access points. It’s differentiated by MACsec AES-256, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, flow-based telemetry, and up to 48 ports of multigigabit performance.
As part of the underlying infrastructure for Juniper Mist™ Wired Assurance, the EX4400 Multigigabit switch 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
AI-Driven Switching
Onboard (day 0), provision (day 1), and manage (day 2+) the EX4400 Multigigabit Ethernet Switch 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 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. Extend EVPN-VXLAN from the campus core to the distribution and access layers for simpler management and greater control and segmentation of endpoints. The Layer 3 IP-based underlay and EVPN-VLXAN overlay interconnects multiple sites.
Microsegmentation
Standards-based microsegmentation using GBP leverages underlying VXLAN technology to provide agnostic endpoint access control. 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.
Flow-Based Telemetry
Enables per-flow level analytics, so you can monitor thousands of traffic flows per switch without impacting the CPU. For example, when flow thresholds are breached, a DDoS attack can be detected quickly. Implement automated workflows to triage problems, such as quarantining a port or examining the traffic.
PoE, PoE++, and Fast PoE
Fast PoE enables power to be provided to the endpoints even as the switch reboots. 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. Fast PoE enables power to be provided to the endpoints even as the switch reboots.

Offering a full suite of Layer 2 and Layer 3 capabilities, the EX4400 enables a variety of deployments, including campus, branch, and data center top-of-rack deployments. As requirements grow, Juniper’s Virtual Chassis technology allows up to 10 EX4400 switches to be seamlessly interconnected and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments.
The EX4400 line consists of eight SKUs:
- The EX4400-48MP, which offers 12 x 100M/1/2.5/5/10GbE and 36 x 100M/1/2.5GbE PoE access ports, delivering up to 90 W per PoE port with an overall total 2200 W of PoE power budget (using two power supplies)
- The EX4400-24MP, which offers 24 x 100M/1/2.5/5/10GbE PoE access ports, delivering up to 90 W per port with an overall total 1776 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W power supplies.
- The EX4400-24T, which offers 24 x 1GbE non-PoE access ports
- The EX4400-24P, which offers 24 x 1GbE PoE access ports, delivering up to 90 W per port with an overall total 1806 W of PoE power budget (using two power supplies). A total PoE budget of 2160 W can be achieved with two optional 1600 W power supplies.
- The EX4400-48T, which offers 48 x 1GbE non PoE-access ports
- The EX4400-48P, which offers 48 x 1GbE PoE access ports, delivering up to 90 W per port with an overall total 2200 W of PoE power budget (using two power supplies)

- The EX4400-48F, which offers 12 x 10GbE SFP+ and 36 x 1GbE SFP fiber access ports
Note: EX4400-24X can be used as an access or a distribution layer switch.
Each EX4400 model offers a choice of optional 4 x 1/10GbE SFP+, a 4 x 10/25GbE SFP28 and a 1 x 100GbE QSFP28 extension module. The EX4400 switches include two dedicated 100GbE ports to support virtual chassis connections, which can be reconfigured to be used as Ethernet ports for uplink connectivity. The 100GbE ports can also accept 40GbE optics for virtual chassis connection or uplink connectivity. EX4400 switches also include high availability (HA) features such as redundant, hot-swappable power supplies and field-replaceable fans to ensure maximum uptime. In addition, PoE-enabled EX4400 switch models offer standards-based 802.3af/at/bt (PoE/PoE+/PoE++) for delivering up to 90 watts on any access port. The EX4400 switches can be configured to deliver fast PoE capability, which enables the switches to deliver PoE power to connected PoE devices within a few seconds of power being applied to the switches. In addition, the EX4400 switches support perpetual PoE, which provides uninterrupted power to connected PoE powered devices (PDs) even when the switch is rebooting.
