How to use
Install the HPE 865408-B21 into a compatible HPE ProLiant server power bay following the server manufacturer’s instructions. Ensure the server is powered down or that hot-swap procedures are observed if replacing a live unit. Connect the AC power within the specified 100–240 V range and verify correct seating and latch engagement. After installation, power on the server and confirm the system recognises the PSU and reports normal operating status in server management tools.
Usage recommendations
To maximise efficiency and service life, maintain proper airflow and ambient temperature in the server chassis, use compatible HPE ProLiant systems, and follow HPE guidelines for spare and replacement parts. For environments requiring higher density or alternative inputs (for example 380 V DC or 48 V DC), consider HPE Flexible Slot power supply options where applicable.
