Juniper Networks EX4400-48P 48-Port PoE+ Ethernet Switch

The Juniper Networks EX4400-48P is a fixed-configuration access switch purpose-built for high-density Power over Ethernet environments in enterprise networks. Launched in 2022-Q1, it delivers 48 ports of 10/100/1000BASE-T PoE+ connectivity alongside 4 upstream SFP+ 10 Gigabit ports for aggregation, supporting simultaneous powering and data delivery to IP cameras, wireless access points, IoT sensors, and unified communication endpoints across sprawling campus facilities.

The architecture centers on Juniper's Trio chipset with a switching fabric delivering line-rate throughput of 104 Gbps, ensuring non-blocking performance across all ports under full load. The platform integrates comprehensive Layer 2/3 switching capabilities with support for VLAN segmentation, rapid spanning tree, and dynamic routing protocols, enabling deployment as both a pure access layer device and a lightweight aggregation point. Power delivery reaches 720W per unit with redundant PSU options, enabling simultaneous PoE+ injection to all 48 ports at full 30W per port—a critical differentiator for dense access scenarios.

Management surfaces include Juniper's Contrail Networking integration for cloud-native deployments, JunOS CLI for traditional automation, and XML API support for third-party orchestration. The switch supports both standalone and stack topologies, allowing operational scaling without architectural redesign. Its compact 1RU form factor fits standard 19-inch racks, reducing datacenter footprint while maximizing port density in edge refresh cycles.

Ideal for

• Campus wireless network backbone: Powering 40+ concurrent 802.11ax access points per switch while maintaining QoS for voice and video traffic
• IP surveillance deployment: Supporting 40-48 powered PoE+ IP camera streams with on-camera analytics processing in retail and enterprise facilities
• IoT sensor networks: Aggregating hundreds of low-power networked sensors across industrial facilities with persistent power and data collection
• Unified communications endpoints: Providing PoE+ to IP phones, video endpoints, and emergency call systems across multi-floor office buildings
• Data-center edge access: Connecting compute nodes, storage appliances, and monitoring equipment in modular or containerized edge deployments
• Temporary event networking: Rapid provisioning of high-density PoE infrastructure for conference centers, exhibition halls, and disaster recovery sites
