EX3400 Ethernet Switches

The EX3400 Ethernet Switches provide a cost-effective, high-performance solution for modern converged enterprise networks carrying data, voice, and video. These compact, fixed-configuration 1U switches deliver management and performance capabilities that were previously limited to high-end access switches.

Cloud-ready and ZTP-enabled, the EX3400 can be easily onboarded, configured, and managed using Juniper Mist™ Wired Assurance, enhancing connected-device experiences. The Juniper Mist Cloud simplifies campus fabric deployment and management, while Mist AI optimizes operations and improves visibility into network performance. Virtual Chassis technology allows up to 10 interconnected EX3400 switches to operate as a single logical device, streamlining management and reducing operational overhead.
