In a Fortune-class data center deploying Juniper EX3400 switches in hot-aisle/cold-aisle rack layouts, the JPSU-150-AC-AFO-EX3400 150W AC power supply front-to-back airflow power cord aligns power delivery with chassis ventilation. By maintaining consistent air pressure and efficient heat extraction, this solution reduces inlet temperatures by up to 12 °C, enhances equipment reliability, and supports continuous 24/7 operations.
For a large university campus running redundant EX3400 switch stacks, the JPSU-150-AC-AFO-EX3400 power cord supports hot-swap power modules without disrupting front-to-back airflow. This ensures uninterrupted 150W power delivery and preserves thermal balance during maintenance windows. Outcome: 99.99% network uptime, streamlined field servicing, and lower mean time to repair (MTTR).
In telecommunications edge sites with limited cooling infrastructure, the JPSU-150-AC-AFO-EX3400 front-to-back airflow power cord delivers stable 150W AC power directly through the airflow path of EX3400 switches. This design minimizes hot spots, extends component life in high-ambient environments, and prevents service interruptions. Benefit: Enhanced network availability and reduced operating costs in remote deployments.
