Description
The JPSU‑920‑AC‑AFO is a high‑capacity 920 W AC power supply unit designed as a field‑replaceable, redundant power module for compatible Juniper EX Series switches. This unit delivers 920 watts of AC power to support high‑performance, PoE‑driven network devices under heavy loads, ensuring continuous operation in demanding enterprise environments. It fits seamlessly into the power supply bays of EX3400 and EX4100 class switches, providing reliable energy delivery with robust electrical protection and well‑managed airflow to keep critical components cool during operation.
Engineered for front‑to‑back airflow (AFO) configurations, this PSU helps maintain consistent thermal conditions in data center racks and network closets that use hot‑aisle/cold‑aisle cooling designs. The unit supports a wide AC input range (100 – 240 VAC, 50;60 Hz), making it suitable for global deployments. Power cord(s) are typically sold separately depending on region and rack setup.
Key Features:
• 920 W AC output to power EX3400 and EX4100 series switches.
• Front‑to‑back airflow (AFO) optimized for rack cooling strategies.
• Wide 100 – 240 VAC input with 50 / 60 Hz support.
• Hot‑swappable design for redundant power configurations.
• Built‑in protections including overvoltage/short‑circuit safeguards.
