HPE A58x0AF 300W AC Power Supply — Back (Power Side) to Front (Port Side) Airflow

Power reliability, efficiency, and easy maintenance come standard with the HPE A58x0AF Back (Power Side) to Front (Port Side) Airflow 300W AC Power Supply. Specifically engineered for HP stackable switches, this 300W PSU delivers steady, clean power to critical network devices while fitting seamlessly into hot-swap bays. The unique back-to-front airflow design moves hot air away from the port-facing area, supporting cooler operation in dense data centers and edge deployments. When uptime matters, this power supply helps minimize downtime, maintain performance under load, and simplify field service, aligning with HP’s reliability standards. Whether you’re refreshing aging hardware or stocking spare parts for a busy network, the A58x0AF is a dependable choice for resilient, scalable networking infrastructure.

• Reliable 300W power output: Provides a robust power baseline for HP stackable switches, enabling sustained throughput, low latency, and stable performance during peak traffic periods. This capacity ensures that even with high port activity, devices stay within safe electrical limits, reducing the risk of reboot events or performance throttling.
• Hot-swappable design: Built for proactive maintenance and rapid replacement, the A58x0AF can be swapped without a full system shutdown in compatible chassis. This minimizes downtime, preserves ongoing workloads, and supports high-availability networking environments.
• Back-to-Front airflow orientation: Engineered to exhaust heat from the port side by drawing cooling air from the power side, improving thermal management in compact racks. This orientation helps maintain optimal thermal margins for HP switches operating in dense deployments.
• Compatibility with select HP stackable switches: Engineered to work with a range of HP stackable switches; verify exact model compatibility in HP’s documentation to ensure proper fit, electrical characteristics, and seamless integration with your chassis.
• Enhanced protection and reliability: Includes overload protection, short-circuit protection, and safe-restart behavior to guard both the power supply and connected network devices against fault conditions, supporting steady uptime and predictable maintenance cycles.

How to Install HPE A58x0AF Power Supply

• Follow your organization’s maintenance policy. For systems configured with hot-swappable PSUs, you can perform the replacement without powering down the entire device, provided you comply with HP guidance and local safety rules.
• Identify the correct PSU bay in the HP switch chassis and prepare the slot by ensuring it is ready to receive the replacement unit; remove any protective covers if present.
• Grip the handle and slide the A58x0AF power supply into the bay until it is fully seated and the latch engages securely; avoid applying excessive force.
• Connect the AC power cord to the PSU and plug the other end into a properly grounded power source or PDU, ensuring cable routing preserves airflow and avoids tension on the connector.
• Power on the device if required and verify the PSU status via the switch’s management interface or front-panel indicators; confirm the supply is detected, delivering power, and contributing to any existing redundancy.
