Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Juniper JPSU-650W-DC-AFI is a purpose-built 650-watt DC power supply unit engineered to deliver stable, high-efficiency power for compatible Juniper Networks platforms. Designed with data center-grade reliability in mind, this PSU supports DC input power, making it well-suited for environments where DC power distribution infrastructure is already in place — a common configuration in carrier, colocation, and purpose-built enterprise data centers.The 'AFI' designation indicates Airflow In (also referred to as front-to-back airflow), which aligns with standard data center hot/cold aisle containment strategies, ensuring that cooling and power delivery work in harmony within your existing rack architecture.
Available in New Open Box condition, this unit has never been installed or put into production use. Original factory packaging may show signs of handling, but the hardware itself remains in like-new condition — providing enterprise-grade reliability at a reduced cost compared to brand-new sealed units.
WhaleyComm sources and inspects New Open Box inventory to ensure customers receive fully functional, authentic Juniper hardware. Whether you are scaling an existing Juniper environment, building a redundant power configuration, or replacing a failed unit, the JPSU-650W-DC-AFI delivers the performance and dependability your infrastructure demands.

Ideal Use Cases
Data Center DC Power Environments
Organizations operating DC-powered data centers can deploy this PSU as a primary or redundant power source within compatible Juniper chassis. Its DC input design integrates cleanly with existing rectifier and bus bar infrastructure common in carrier-grade facilities.
Redundant Power Configuration
Network engineers building high-availability Juniper deployments can use the JPSU-650W-DC-AFI to establish N+1 or fully redundant power configurations. Redundant PSUs help eliminate single points of failure and support continuous uptime during maintenance or unexpected power events.
Sparing and Inventory Management
IT procurement teams and managed service providers can stock the JPSU-650W-DC-AFI as a critical spare for rapid field replacement. New Open Box condition ensures the spare is deployment-ready while keeping acquisition costs optimized.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
AFI stands for Airflow In, meaning air enters the power supply from the front of the chassis and exhausts out the rear. This airflow direction is also commonly referred to as front-to-back and is designed to align with standard cold-aisle/hot-aisle data center containment configurations.
New Open Box units have never been installed or used in a production environment, but the original factory packaging has been opened or may show handling wear. The hardware itself is in like-new condition, making it a cost-effective alternative to new sealed product without sacrificing reliability.
No — the JPSU-650W-DC-AFI is specifically designed for DC input power. If your environment requires AC input, please contact WhaleyComm to identify the appropriate AC variant for your Juniper platform.
Compatibility depends on your specific Juniper chassis model, software version, and existing power configuration. We recommend consulting the Juniper Networks Hardware Compatibility Guide or contacting WhaleyComm's technical sales team, who can assist in confirming the correct power supply for your deployment.
