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.

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 802.3bz Multigigabit
• 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, pay-as-you-grow solution for expanding network environments.

Virtual Chassis Technology

Juniper’s Virtual Chassis technology allows multiple interconnected switches to operate as a single, logical unit, enabling users to manage all platforms as one virtual device. Up to 10 EX4400 switches can be interconnected as a Virtual Chassis using two dedicated 100GbE rear-panel ports. Although configured as Virtual Chassis ports by default, the 100GbE uplinks can also be channelized as 4 x 10GbE/25GbE Ethernet uplink ports. The EX4400 switches can form a Virtual Chassis with any other models within the EX4400 product line.
