HPE 1000W M-crps -48VDC HOT Plug Reverse AIR Flow Power Supply KIT - P79329-B21

HPE P79329-B21 Concise Descriptor

Overview

The HPE P79329-B21 is a 1000W, -48VDC, hot-plug power supply unit designed for high-availability server and network equipment. Its reverse airflow configuration is critical for specific chassis designs where airflow must be drawn from the front and exhausted from the rear, ensuring optimal thermal management in dense rack environments. This power supply kit is essential for maintaining continuous operation of critical IT infrastructure, including surveillance systems that rely on uninterrupted power to NVRs and network switches.

Compatibility

This power supply kit is engineered for specific HPE ProLiant server and Synergy compute module configurations that require -48VDC input and a reverse airflow path. It is not a universal power supply and must be matched to the server chassis's power bay and airflow requirements. Consult your server's technical documentation for exact compatibility with models such as specific HPE Synergy frames or ProLiant DL/ML servers designed for -48VDC input and reverse airflow.

Installation Notes

Installation requires the server or compute module to be powered down. The hot-plug design allows for replacement without system downtime if a redundant unit is installed. Ensure the unit is firmly seated in the power bay and the locking mechanism is engaged. The reverse airflow design means this unit must be installed in chassis bays specifically designed to accept air from the front and exhaust it from the rear.
