Juniper EX4000-12MP Cloud-Native Ethernet Switch with 12 Multi-Gigabit PoE++ Ports

Product Overview

The Juniper EX4000-12MP Ethernet Switch delivers cloud-managed, AI-assisted access switching for enterprise branches, remote offices, and campus networks. Part of the Juniper EX4000 Series, this switch combines high-performance Ethernet connectivity with multi-gigabit support and IEEE 802.3bt PoE++ for modern wireless access points, IoT devices, IP phones, cameras, and other powered endpoints.

Cloud-Native Management

Built for Juniper Mist Wired Assurance, the EX4000-12MP can be onboarded, configured, monitored, and managed from the cloud. Mist AI and the Marvis Virtual Network Assistant help simplify network operations, improve visibility into connected-device experiences, and accelerate troubleshooting. Layer 2 and Layer 3 capabilities support flexible deployment across growing business environments, while management features provide centralized control over setup and configuration.

Performance and Power

The switch provides 12 Ethernet ports with IEEE 802.3bz multi-gigabit capabilities to help increase available network bandwidth for Wi-Fi 6E and Wi-Fi 7 access points. IEEE 802.3bt PoE++ supplies up to 60 watts per port for compatible powered devices. Fast and Perpetual PoE features help maintain power continuity during switch operations, reducing disruption to connected equipment. The EX4000-12MP also supports Virtual Chassis technology, allowing up to six compatible EX4000 switches to be managed as a single logical device for simplified administration and scalable expansion.

Deployment Flexibility

Designed for access-layer installations, the Juniper EX4000-12MP supports wall-mounting and DIN rail mounting options to help organize cabling and accommodate a variety of deployment environments. Gigabit Ethernet and twisted-pair cable support provide reliable connectivity over cable runs up to 328 feet. With its compact fixed-form-factor design, multi-gigabit performance, PoE++ power delivery, and Juniper Mist integration, the EX4000-12MP is a practical foundation for cloud-managed wired networks.
