JL632A Aruba 8325 650W 100-240VAC FB PSU

The Aruba X391 (JL632A) is a mission-critical AC power supply module engineered specifically for the Aruba 8325 Switch Series. This 650W unit is designed to meet the rigorous electrical demands of high-density 25G/100G data center switching. Featuring a Port-to-Power (Front-to-Back) airflow configuration, the JL632A ensures that the switch's thermal management remains perfectly synchronized with standard "Cold Aisle" intake strategies, providing the reliable energy foundation required for non-stop network fabric operations.

• Optimized Data Center Airflow: The JL632A is a "Front-to-Back" (FB) model, meaning it pulls cool air from the switch port side and exhausts heat out the power supply side. This is essential for maintaining pressure balance in data center containment systems, preventing expensive hardware "hot spots."

• Platinum-Grade Power Conversion: With an efficiency rating exceeding 94%, this PSU minimizes energy waste during AC-to-DC conversion. This high efficiency translates directly to lower heat output, which preserves the lifespan of internal switch components and reduces the load on rack cooling fans.

• Redundant Power Architecture ($N+N$): When dual JL632A units are installed in an Aruba 8325 chassis, they operate in an active-active load-sharing mode. In the event of a power source failure, the remaining PSU instantly assumes the full 6.4 Tbps switching load with zero impact on data throughput.

• AOS-CX Intelligent Monitoring: The JL632A communicates directly with the Aruba AOS-CX operating system. IT teams can leverage the Network Analytics Engine (NAE) to monitor real-time wattage draw, input voltage stability, and thermal health, enabling predictive maintenance.

• High-Density Data Center Reliability: Built with premium, industrial-grade capacitors, the JL632A is designed for 24/7/365 operation. It provides the "Five Nines" ($99.999%$) availability required for high-frequency trading, cloud service providers, and enterprise cores.

• Operational Continuity (Hot-Swap): The modular, hot-swappable design allows technicians to replace a power unit in seconds without powering down the switch. This eliminates the need for maintenance windows and ensures that critical 100G links stay active.

• Reduced OPEX through Efficiency: By achieving Platinum-level efficiency, the JL632A reduces total electricity consumption and HVAC cooling costs. Over a large-scale deployment, these savings significantly lower the Total Cost of Ownership (TCO).

• Global Infrastructure Ready: The universal auto-ranging input ($100V$-$240V$) allows this single SKU to be deployed in any global region. Whether operating on $110V$ in North America or $220V$ in Dubai and Shenzhen, the hardware adjusts automatically, simplifying international logistics and spare-parts inventory.
