Juniper EX4400 Multigigabit Ethernet Switch

The EX4400 Multigigabit Ethernet Switch is a cloud-ready, AI-powered access switch designed for high-performance campus deployments. It delivers multigigabit speeds of 100M/1/2.5/5/10GbE and advanced power capabilities (PoE, PoE++) for Wi-Fi 6, 802.11ac access points, high-density IP phones, and IoT devices.

The switch is distinguished by MACsec AES-256 encryption, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, flow-based telemetry, and support for up to 48 multigigabit ports.

Integrated with Juniper Mist™ Wired Assurance, the EX4400 Multigigabit switch is easy to onboard, configure, and manage. The Juniper Mist Cloud simplifies deployment and campus fabric management, while Mist AI improves operational visibility and device performance insights.
