Juniper JPSU‑150‑AC‑AFO 150 W AC Front‑to‑Back Airflow Power Supply

The Juniper JPSU‑150‑AC‑AFO is a compact and reliable 150 W AC power supply unit designed as a field‑replaceable module for compatible Juniper EX Series Ethernet switches that use the AFO (front‑to‑back airflow) chassis configuration. It provides stable and efficient power delivery for small to medium PoE deployments and non‑PoE systems where a 150 W budget is sufficient.

With a wide AC input voltage range of 100 – 240 VAC (50/60 Hz), this PSU is suitable for global installations and offers built‑in protections against overvoltage, short circuits, and overheating to ensure dependable operation in enterprise networking environments. Its front‑to‑back airflow orientation is optimized for racks and data‑center cooling designs, particularly hot‑aisle/cold‑aisle layouts, helping maintain proper thermal balance across system components.

The hot‑swappable design allows for zero‑downtime replacement or addition in redundant power configurations, enabling increased uptime and simplified maintenance without disrupting network operations.

Key Features:
• 150 W AC output for powering compatible Juniper switches.
• Front‑to‑back airflow (AFO) for efficient rack cooling and consistent thermal performance.
• Wide AC input range (100–240 VAC, 50/60 Hz) for global compatibility.
• Hot‑swappable module supports redundant PSU setups.
• Built‑in electrical protections for safety and reliability.
