S0U53A#ABA HPE 1600W AC Aruba Networking CX 5420 Power Supply.

S0U53A#ABA HPE 1600W AC Power Supply for Aruba CX 5420 Series

The S0U53A#ABA power module, designed by Hewlett Packard Enterprise (HPE), delivers a robust 1600 W AC power capacity specifically tailored for Aruba Networking’s CX 5420 switch platform. Crafted for enterprise-grade stability and efficiency, it supports data-center-grade operations with energy-conscious design and plug‑and‑play interchangeability

Manufacturer Assurance & Certification

HPE’s S0U53A#ABA unit is backed by rigorous factory validation and global quality standards: reliability testing, thermal regulation, and compliance with enterprise power norms ensure long-term durability. Certifications include North American and international safety marks, eco‑friendly energy ratings, and compatibility with data‑center environmental specifications.

Deployment Scenarios

This high-wattage power supply is optimal for environments requiring non-stop performance from Aruba CX 5420 series switches.

• Data centers with continuous uptime demands
• High-density aggregation for campus or branch networks
• High-availability network backbones with dual PSU redundancy
• Enterprise environments where energy efficiency and modular maintenance are crucial

Redundancy & Fault Tolerance Design

When paired in dual‑PSU configurations, this 1600 W unit offers automatic fail-over and load balancing, enabling uninterrupted service even during replacement or maintenance. Front removal and insertion support facilitate hot-swap operations, minimizing service disruptions and supporting routine repairs or upgrades.

Performance & Energy Efficiency Advantages

HPE’s 1600 W AC supply is engineered not only for power headroom but also for energy optimization. High-efficiency components reduce wasted energy and thermal output, helping lower total cost of ownership (TCO) while maintaining performance under peak network load.

Eco‑Efficiency Measures

• Efficient AC to DC conversion with low-energy loss
• Advanced thermal management to decrease cooling demands
• Designed to meet or exceed ENERGY STAR® and similar rating standards
• Enables better energy budgeting within network operations

Diagnostic & Capabilities

The unit supports real-time health checks, including alerting for voltage level, temperature, load, and failure events. Integration with Aruba’s network management suite gives administrators granular visibility into PSU status, enabling proactive maintenance and quicker fault detection.

Comparative Evaluation with Alternative Models

In contrast to lower-wattage or third‑party modules, the S0U53A#ABA offers OEM-engineered compatibility, better thermal profiles, and simplified firmware integration. Enterprises benefit from smoother firmware updates, certified performance, and predictable support—a critical advantage over generic or unverified alternatives.

This Makes It Stand Out

• Guaranteed mechanical and electrical alignment with Aruba CX 5420 chassis
• Minimized risk of firmware incompatibility or device rejection
• Pre‑qualified by HPE for thermal and electrical load demands
• Direct path to warranty and replacement support

Deployment Efficiency & Lifecycle

Network administrators can simplify inventory and maintenance with a modular approach. Keeping S0U53A#ABA modules on hand reduces downtime and streamlines lifecycle replacements for Aruba CX 5420 infrastructures.

Lifecycle Workflow Benefits

• Easy swap‑in, swap‑out process for quick maintenance tasks
• Consistent part numbering (S0U53A#ABA) across global support systems
• Predictable power budgeting for capacity planning
• Supports phased hardware refresh strategies in network rollouts

Optimized for Business Continuity

This power supply underpins critical uptime objectives with its built-in redundancy capabilities, thermal resilience, and compatibility. It supports business continuity plans by reducing points of failure and simplifying emergency maintenance cycles.
