This is a genuine Juniper 850W 80+ Platinum Hot-Swap AC Power Supply (P/N: JPSU-850W-AC-AFO). This high-efficiency module is engineered to provide stable and reliable power for Juniper QFX5100 and QFX5200 series network switches. A critical feature of this power supply is its AFO (Airflow Out) design, indicating a front-to-back cooling direction, which is essential for maintaining proper thermal management in modern data center racks.
Key Features
-
Genuine Juniper Part: Ensures perfect fit, function, and compatibility with the power and management systems of Juniper QFX5100 and QFX5200 switches.
-
AFO (Front-to-Back) Airflow: This power supply is designed with "Airflow Out," meaning it pulls cool air from the front of the chassis (the cold aisle) and exhausts hot air out the back (the hot aisle). This is a critical specification that must match the switch's fan modules.
-
80 Plus Platinum Efficiency: With a Platinum efficiency rating, this PSU minimizes wasted energy, reducing operating costs and heat output in your network closet or data center.
-
Hot-Swap Redundancy: The module is hot-swappable, allowing for easy replacement or the addition of a second unit for power redundancy without network downtime.
