267555-B21 - HP 550-Watts Hot-pluggable Power Supply (with IEC Cord) Proliant DL560

Description

The HP 267555-B21 is a 550-watt redundant power supply unit (PSU) designed to ensure high availability and continuous operation for compatible HP server systems. In a redundant configuration, two or more PSUs work in parallel, with one typically handling the load while others are on standby or sharing the load. This architecture is critical for mission-critical applications where downtime is unacceptable. If one power supply unit fails, the remaining unit(s) automatically take over the full power load without interruption to the server's operation. This feature significantly enhances the reliability and fault tolerance of the server infrastructure. The 550-watt capacity is suitable for a wide range of server configurations, providing ample power for processors, memory, storage, and other components. Furthermore, this power supply is designed for hot-plug functionality, meaning it can be safely removed and replaced while the server is still running. This capability minimizes downtime during maintenance or in the event of a PSU failure, allowing for quick and seamless replacement without needing to power down the entire system. The 267555-B21 is a key component for maintaining robust and resilient server operations in demanding enterprise environments.
