DESCRIPTION

EX4400-24MP — Compact Multigigabit PoE++ Switching for AI-Driven Enterprise Access

The Juniper EX4400-24MP is a compact, high-performance multigigabit access switch designed for modern enterprise campuses that rely on Wi-Fi 6/6E, IoT, and smart building technologies. Featuring 24 multigigabit 100M/1/2.5/5/10GbE PoE++ access ports, EVPN-VXLAN support, and seamless integration with Mist AI, the EX4400-24MP delivers powerful access-layer performance in environments where density is important but rack space is limited. As part of the Juniper EX4400 Series, this model is ideal for wiring closets, branch sites, and distributed edge deployments where flexibility and power efficiency matter.

Key Features:

  • Multigigabit Access: All 24 ports support 100M/1/2.5/5/10GbE, enabling full performance for Wi-Fi 6/6E APs and high-speed edge devices.
  • High PoE++ Budget: Supports 90W per port with a chassis PoE budget suitable for APs, cameras, sensors, and IoT infrastructure.
  • Automation: Integrated with Mist Wired Assurance, Marvis VNA, ZTP, and open APIs for simplified onboarding and operations.
  • Security: MACsec, microsegmentation, group-based policies (GBP), and identity-based access controls protect users and devices.
  • Scalability: 100GbE stacking and 10/25GbE uplinks allow easy scaling as bandwidth demands grow.
  • High Availability: Redundant, hot-swappable power supplies and fans ensure carrier-class uptimes for enterprise environments.

Multigigabit Access and PoE++ for High-Performance Edge Devices

The EX4400-24MP provides high-speed PoE++ access to support dense deployments of powered devices such as advanced wireless APs, IP surveillance, smart sensors, and automation systems. With 24 ports of full multigigabit capability, this model is ideal for closets or branch sites that need next-generation performance without the port count of a larger switch.

  • PoE++ (90W): Supplies high-power devices including Wi-Fi 6/6E APs, PTZ cameras, LED lighting, and industrial IoT controllers.
  • Compact Density: 24 multigigabit ports provide flexibility for environments where 48-port switches would be underutilized.
  • Investment Protection: Supports existing cabling while enabling migrations to higher edge bandwidth.

AI-Native Operations with Mist Cloud

The EX4400-24MP integrates directly with Juniper Mist cloud services to bring AI-driven automation, visibility, and troubleshooting to wired access networks.

  • Mist Wired Assurance: Provides real-time performance baselines, anomaly detection, and automated switching diagnostics for EX4400 deployments.
  • Marvis VNA: Uses AI to identify user-impacting issues and offer actionable remediation steps.
  • Streaming Telemetry: JTI, gRPC, and OpenConfig feed high-resolution telemetry to cloud and on-prem monitoring tools.
  • Zero Touch Provisioning: Automates onboarding for rapid and large-scale deployments.

Flexible Uplinks and High-Performance Architecture

The EX4400-24MP supports a variety of uplink and stacking configurations to meet performance and growth requirements across diverse campus and branch environments.

  • Uplink Options: Supports optional 4 x 1/10GbE SFP+ or 4 x 1/10/25GbE SFP28 uplinks.
  • 100GbE Stacking: Two dedicated 100GbE ports enable high-speed Virtual Chassis stacking or uplinks to core switches.
  • Non-Blocking Fabric: Hardware architecture provides consistent performance during heavy traffic and PoE loads.

Rugged Enterprise Hardware Design

Designed for long life and reliable performance, the EX4400-24MP is built with enterprise-grade components and environmental efficiency.

  • Compact 1RU Form Factor: Fits standard 19” racks, ideal for remote branches and space-constrained closets.
  • Redundant Hardware: Hot-swappable PSUs and fan trays ensure continuous operation and simplified serviceability.
  • Efficient Cooling: Available in AFO/AFI variants (SKU-specific), allowing compatibility with data center and IDF airflow designs.

Campus Fabric Integration and Segmentation

The EX4400-24MP extends Juniper’s advanced EVPN-VXLAN fabric capabilities to the access layer, enabling centralized policy, segmentation, and automation.

  • EVPN-VXLAN: Brings data center-class segmentation to campus access networks. For a deeper comparison, review our Juniper QFX vs EX Series guide.
  • Virtual Chassis: Up to 10 EX4400 units can operate as a single logical switch.
  • Microsegmentation: Uses group-based policies to isolate users, applications, and devices.

Security Built In

Security features are embedded throughout the EX4400 platform to protect campus users and connected devices.

  • MACsec AES-256: Encrypts sensitive traffic between access and core layers.
  • Identity Enforcement: 802.1X, MAC authentication, dynamic VLAN assignment, and policy-based access control.
  • L2/L3 Protection: Control Plane Policing (CoPP), DHCP snooping, DAI, and RA Guard.
