Description

The HP HSTNS-PL28, HP part numbers 643931-001 and 643954-201, is a 460W Common Slot (CS) Platinum Plus hot-plug switching power supply designed for HP ProLiant enterprise servers.

It accepts 100–240V AC input and provides regulated +12V DC power to the server's processors, memory, storage and I/O components. Its hot-plug design allows the PSU to be removed and replaced without shutting down the server when the system is configured with redundant power supplies.

The HSTNS-PL28 is primarily associated with HP ProLiant Gen8 server platforms, including the DL360p, DL380p, DL385p and ML350p families. The exact compatibility depends on the server configuration and existing Common Slot power-supply arrangement.

HP and server-parts documentation also identifies the following related numbers for this PSU: 660184-001 as the spare part and 656362-B21 as the option kit.
