HP 355892-B21 575-Watts Redundant Power Supply For DL380 Gen4 Server
The HP 355892-B21 575-Watts Redundant Power Supply is a genuine enterprise-grade hot-plug power module built to keep compatible HP ProLiant DL380 Gen4 servers running without interruption. Rated at 575 watts, it accepts a wide 100–240V AC input range, making it suitable for varied data center power setups across different regions.
This power supply ships as a complete Hot-Plug AC Redundant Power Supply Module with an IEC cord included, and it is purpose-built for HP ProLiant DL380 G4 chassis. It can be installed as a single unit or paired with a second module in a redundant N+1 configuration, so the second supply keeps the server powered if the first fails.
Built with hot-plug support, the 355892-B21 can be inserted or removed while the server remains operational, simplifying maintenance and part replacement for IT teams managing live production servers. It is commonly cross-referenced with related HP part numbers such as 321632-501, 367238-501, 338022-001, and 406393-001.
