EX4400 PoE models support IEEE 802.3bt (PoE++) delivering up to 90W per port — powering next-generation Wi-Fi 7 APs, pan-tilt-zoom IP cameras, digital displays, and thin-client terminals directly from the switch. Total PoE budget of up to 2,200W enables 48-port deployments with simultaneous high-power device connectivity.
EX4400 supports BGP EVPN with VXLAN encapsulation — enabling Layer 2 overlay networks across routed campus fabrics. IP-routed access layer architecture with EVPN-VXLAN eliminates traditional Spanning Tree Protocol (STP) limitations while providing seamless VM and workload mobility across buildings and campus sites.
MACsec (IEEE 802.1AE) with AES-256 encrypts all traffic at the Ethernet layer on every port — providing line-rate encryption between switches, between switch and server, and between switch and endpoint. MACsec protects data in transit across untrusted network segments without performance penalty.
EX4400-48MP and EX4400-24MP models deliver 12–24 ports of 100M/1/2.5/5/10GbE multigigabit per switch, auto-negotiating to the highest speed supported by the connected device. Essential for Wi-Fi 6E AP backhaul, eliminating the need for separate 10GbE access layer switches.
Optional uplink expansion modules (EX4400-EM-4S for 4 × SFP+, EX4400-EM-4F for 4 × 25GbE SFP28, or EX4400-EM-1F for 1 × 100GbE QSFP28) provide flexible uplink speeds — allowing the same EX4400 hardware to connect into 10GbE, 25GbE, or 100GbE aggregation layers without hardware replacement.
EX4400 integrates with Juniper Mist Wired Assurance for AI-native cloud management. Dynamic port profiles automatically apply correct configurations when devices connect. Flow-based telemetry streams per-port analytics to Mist, enabling AI-driven troubleshooting that identifies root causes — such as duplex mismatches or PoE budgeting issues — before users notice a problem.
The Juniper EX4400 is Juniper's flagship enterprise access switch, purpose-built for organisations deploying Wi-Fi 6/6E/7, high-density PoE++, and EVPN-VXLAN campus fabrics. Available in eight SKUs covering 24 and 48-port configurations with 1GbE, multigigabit (up to 10GbE per port), and all-fiber options, the EX4400 covers every access-layer scenario from standard office connectivity through to high-performance wireless backhaul and data-centre-edge deployments.
The PoE++ capability (IEEE 802.3bt, 90W per port) distinguishes the EX4400 in the enterprise market — it can power next-generation Wi-Fi 7 access points, high-resolution PTZ cameras, intelligent lighting systems, and digital signage from a single Ethernet cable with PoE budget headroom to spare. The 2,200W total PoE budget on dual-PSU configurations supports full 48-port PoE++ populations, a requirement often unmet by competing access switches.
EVPN-VXLAN support makes EX4400 suitable for modern routed-access campus architectures, eliminating reliance on Spanning Tree Protocol and enabling seamless layer-2 connectivity across IP-routed underlay networks. MACsec AES-256 encryption on all ports ensures data confidentiality across every campus segment — a requirement for regulated industries and organisations handling sensitive data across multi-building campus networks. All EX4400 models integrate with Juniper Mist for cloud-native operations.
Multigigabit EX4400-MP ports provide 2.5–10GbE uplinks to next-generation Wi-Fi APs, preventing wireless backhaul bottlenecks. PoE++ (90W) powers latest-generation tri-band Wi-Fi 7 APs that exceed standard PoE+ budgets.
EVPN-VXLAN support enables routed-access campus architectures without Spanning Tree, with consistent L2 connectivity across buildings. Mist AI wired assurance provides IT teams with per-client visibility and AI troubleshooting at scale.
IEEE 1588 PTP precision timing and MACsec encryption make EX4400 suitable for OT/SCADA environments requiring sub-microsecond time synchronisation and data-in-motion security across factory floor networks.
MACsec AES-256 end-to-end encryption satisfies compliance requirements for PCI-DSS, ISO 27001, and HIPAA data-in-transit controls across campus Ethernet segments — encrypting inter-switch links and edge ports simultaneously.
