Juniper EX3400-48T-AFI 48-Port Switch | Back-to-Front Airflow, Enterprise

Maintain cleaner thermal design in dense network racks with the Juniper EX3400-48T-AFI, a 48-port managed switch configured for back-to-front airflow. In environments where switch orientation must match the cooling architecture, airflow direction is not a detail — it is part of the operational plan. This model helps infrastructure teams preserve rack-level cooling strategy while delivering high port density for access-layer connectivity. The 48-port configuration supports larger endpoint concentrations, aggregation points, and access closets that need more density without moving to a different class of platform. For organizations standardizing on Juniper switching, the EX3400 family provides a familiar operational model with the added benefit of airflow alignment for specific deployment requirements. Choose this switch when thermal management, rack design, and port density all matter. It is well suited to environments where equipment placement is constrained by airflow policy, or where network teams need to preserve consistent cooling paths across adjacent hardware. The EX3400-48T-AFI gives enterprise buyers a practical reason to choose a more specific model: it solves a real deployment constraint while supporting a larger access footprint.
