HPE S0U53A Aruba CX 5420 1600W AC Power Supply Unit
Overview
The HPE S0U53A is a high-efficiency, 1600-watt AC hot-swappable power supply unit designed specifically for the HPE Aruba Networking CX 5420 Switch Series chassis. Its primary purpose is to provide stable, reliable, and redundant power to these modular network switches, ensuring continuous operation and high availability in demanding enterprise campus and branch environments. This component is critical for maintaining network uptime for critical infrastructure. This power supply is engineered for seamless integration, supporting the high-power requirements of a fully populated CX 5420 chassis, including high-density line cards and Power over Ethernet (PoE) modules. The unit’s design ensures efficient power conversion, which helps to minimize energy consumption and reduce operational costs within the data center or network closet. It operates on a standard AC input voltage, making it suitable for global deployments. As a hot-swappable component, the S0U53A allows for replacement or addition without powering down the entire network switch, a crucial feature for maintaining business continuity. This capability, combined with the ability to deploy multiple units for N+1 redundancy in a compatible chassis, provides a robust power framework. This ensures that the network remains resilient against a single power supply failure, safeguarding critical business operations.
