Comprehensive Product Overview

The Juniper EX3400-24P belongs to Juniper’s EX3400 Series of compact, fixed-configuration access switches, built to balance performance, scalability, and cost-efficiency for modern enterprise networks. As a PoE+ enabled model, it provides up to 370W–720W PoE budget (configurable) to support power-hungry edge devices without separate power adapters.

Engineered with Juniper Virtual Chassis Technology, the EX3400-24P allows up to 10 switches to be interconnected and managed as a single logical device, simplifying network scaling and reducing operational overhead. It supports Juniper Mist Cloud Architecture with zero-touch provisioning (ZTP), enabling fast deployment and AI-powered automation for consistent service levels.

Optimized for both enterprise campus wiring closets and data center access layers, the switch features front-to-back airflow, redundant hot-swappable fans, and support for redundant AC/DC power supplies (600W included, 920W optional) for high reliability. Running on Junos OS, it delivers enterprise-grade Layer 3 routing, advanced QoS, MACsec encryption, and comprehensive security features to protect against network threats.
