48x1G POE switch with 2x100G uplink/stacking ports. 90W POE. MACsec AES256 capable (optional license sold separately). Optional extension module(sold separately): 4x10G or 4x25G
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.
Key features of the EX4400 include:
• Cloud-ready, driven by Mist AI with Juniper Mist Wired Assurance and Marvis Virtual Network Assistant
• Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) to the access layer
• End-to-end encryption using Media Access Control Security (MACsec) AES256
• IEEE 802.3bt Power over Ethernet (PoE++)
• Standards-based microsegmentation using group-based policies (GBP)
• Flow-based telemetry to monitor traffic flows for anomaly detection
• Precision Timing Protocol – Transparent clock
• 10-member Virtual Chassis support
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, payas-you-grow solution for expanding network environments.
