Juniper JPSU‑350‑AC‑AFO 350 W AC Front‑to‑Back Airflow Power Supply

The Juniper JPSU‑350‑AC‑AFO is a high‑efficiency 350 W AC power supply unit designed as a field‑replaceable module for compatible Juniper EX Series switches and other networking platforms that use the AFO (front‑to‑back airflow) power supply form factor. Built to deliver consistent and reliable power, this PSU supports a wide 100 – 240 VAC input range (50/60 Hz), making it suitable for global deployments. Its front‑to‑back airflow (AFO) orientation helps maintain proper cooling and thermal balance in rack environments that follow hot‑aisle/cold‑aisle designs, ensuring optimal performance even under heavy load.

The unit is hot‑swappable, allowing for non‑disruptive replacement or redundancy in dual PSU configurations. With built‑in protections against overvoltage, overheating, and short circuits, the JPSU‑350‑AC‑AFO contributes to stable operation and longer hardware lifespan. It is typically used to power mid‑range enterprise Ethernet switches where a 350 W budget is sufficient to support performance and any integrated PoE components (if supported).

Key Features:
• 350 W AC output suitable for powering compatible Juniper switches and networking gear.
• Front‑to‑back airflow (AFO) optimized for rack cooling and thermal design.
• Wide voltage input range (100 – 240 VAC, 50/60 Hz) for flexible deployment worldwide.
• Hot‑swappable design supports redundant PSU configurations.
• Built‑in protections including overvoltage and short‑circuit safeguards.
