HP 225011-001 DL380 G2 Hot Plug Redundant Power Supply

The HP 225011-001 is a 400W hot-plug redundant power supply engineered for HP ProLiant DL380 Generation 2 and Generation 3 rack servers, as well as StorageWorks NAS B2000 and Tasksmart C series systems. In environments where uptime is critical, redundant power supplies allow one unit to be removed and replaced while the server continues running on the remaining supply, eliminating the need for planned downtime during a power supply failure or proactive replacement.

As a legacy component for servers that are now several generations old, this power supply is most relevant to organizations still operating DL380 G2 or G3 hardware—whether in production, lab, or archival roles. The hot-plug form factor slides directly into the server's power bay, and the 400W output matches the original factory specification, ensuring electrical compatibility without configuration changes. For anyone maintaining these older HP systems, keeping a spare 225011-001 on hand is a practical measure to protect against unexpected power supply failures.
