Juniper EX4400-48MP | 48-Port Multigigabit PoE+ Switch

EX4400-48MP — Multigigabit PoE++ Switching for Modern AI-Driven Campus Networks

• Scalability: 48 multigigabit access ports (12 x 100M/1/2.5/5/10GbE and 36 x 100M/1/2.5GbE) support current Wi-Fi 6/6E and future Wi-Fi 7 access points without rewiring, with an easy upgrade path across the Juniper EX Series portfolio.
• Performance: High-performance switching with non-blocking throughput and hardware-accelerated Layer 2/Layer 3 services for latency-sensitive applications such as collaboration, video, and real-time analytics.
• Automation: Native integration with Juniper Mist Wired Assurance, Marvis Virtual Network Assistant, ZTP, and open APIs streamlines provisioning, monitoring, and troubleshooting.
• Reliability: Redundant, hot-swappable power supplies and field-replaceable fan trays, combined with Virtual Chassis support, deliver high availability and simplified scaling.
• Security: MACsec AES-256, standards-based microsegmentation using group-based policies (GBP), and robust access control features provide end-to-end protection at the access layer.
• Flexibility: Optional 10/25GbE uplinks, 100GbE stacking, and EVPN-VXLAN support make the EX4400-48MP suitable for campus access, distribution, and small data center top-of-rack roles.

Multigigabit Access with High-Power PoE++

• PoE++ Power: Supports up to 90W per access port, ideal for Wi-Fi 6/6E APs, PTZ cameras, and high-draw IoT devices.
• Total PoE Budget: Up to 2200W PoE budget with dual power supplies, enabling high-density powered device deployments on a single switch.
• Multigigabit Speeds: 100M/1/2.5/5/10GbE access ports protect cabling investments while providing a clear path to higher throughput at the edge.

AI-Native Telemetry and Automation

• Mist Wired Assurance: Cloud-based onboarding, configuration, and lifecycle management improve time-to-service and reduce human error for EX4400 campus deployments.
• Marvis Virtual Network Assistant: Uses AI/ML to detect anomalies, suggest corrective actions, and help predict issues before users are impacted.
• Streaming Telemetry: Flow-based telemetry, JTI, and support for gRPC and OpenConfig enable high-frequency metrics and deep performance visibility.
• Open Automation: Supports Zero Touch Provisioning (ZTP), REST APIs, Ansible, and Python automation for integration into existing NetOps workflows.

High Throughput and Flexible Uplink Options

• Switching Capacity: Non-blocking architecture designed to handle multigigabit access traffic and high-density PoE deployments without oversubscription at the switch backplane.
• Extension Modules: Optional 4 x 1/10GbE SFP+ or 4 x 1/10/25GbE SFP28 uplink modules provide design flexibility as bandwidth demands grow.
• 100GbE Stacking/Uplinks: Dedicated 100GbE ports support Virtual Chassis stacking or can be used as high-speed uplinks into campus cores or distribution layers.

Enterprise-Ready Hardware and Environmental Efficiency

• Form Factor: 1RU fixed-configuration chassis designed for standard 19” racks, with all ports accessible from the front.
• Redundant Components: Redundant, hot-swappable power supplies and fan trays maximize uptime and simplify serviceability.
• Airflow: Front-to-back airflow (AFO) aligns with typical data center and wiring-closet cooling designs, reducing hotspots and improving thermal efficiency.
• Operational Efficiency: Designed for efficient power consumption while delivering high PoE budgets, supporting sustainability and cost-control initiatives.

Regulatory Compliance and Environmental Standards

• RoHS: Restriction of Hazardous Substances compliance for environmentally responsible hardware.
• REACH: Registration, Evaluation, Authorization and Restriction of Chemicals compliance to support EU regulatory requirements.
• WEEE: Waste Electrical and Electronic Equipment Directive adherence, supporting responsible recycling and end-of-life handling.

Campus Fabric Integration and Scalable Architectures

• EVPN-VXLAN: Extends EVPN-VXLAN overlays to the access layer, enabling scalable, segmented campus architectures with consistent policies end to end. For a broader comparison of campus and data center options, see our guide on Juniper QFX vs EX Series switches.
• Virtual Chassis: Up to 10-member Virtual Chassis support allows multiple EX4400 switches to operate as a single logical device with simplified management.
• Flexible Roles: Can act as an access switch in large enterprises, an aggregation switch in smaller campuses, or a top-of-rack platform for branch data center pods.

Security Built In

• MACsec AES-256: Provides line-rate encryption on supported ports, securing traffic between access and distribution layers.
• Access Control: Supports 802.1X, MAC authentication, and dynamic VLAN assignment, enforcing identity-based policies at the edge.
• Microsegmentation: Group-based policies (GBP) and EVPN-VXLAN enable fine-grained segmentation for users, devices, and applications.
• Control Plane Protection: Control Plane Policing (CoPP), DHCP snooping, dynamic ARP inspection, and RA Guard help mitigate common Layer 2/Layer 3 attacks.
