Product Description
The HP 864450-B21 is a high-efficiency, 500-watt AC power supply unit specifically designed for use in HP ProLiant server environments. Operating at 240V AC, this power supply is built to meet the demanding power requirements of enterprise-grade servers, ensuring stable and reliable operation. Its primary function is to convert incoming AC power into the DC voltages required by the server's internal components. A key feature of this power supply is its redundant design. When installed in pairs within a compatible server chassis, these units provide N+1 or 1+1 redundancy. This means that if one power supply fails, the other(s) can seamlessly take over the entire power load without interruption to the server's operation. This redundancy is critical for maintaining high availability and preventing costly downtime in mission-critical applications. Furthermore, the 864450-B21 is typically hot-swappable, allowing it to be removed and replaced while the server is still running, provided a redundant unit is installed. This capability simplifies maintenance and upgrades, further contributing to the overall uptime and reliability of the server infrastructure. Its compatibility is generally with specific generations and models of HP ProLiant servers, making it an essential component for maintaining the integrity of HP server deployments.
