Server power module

The HP HSTNS-PF04 is a 750W Common Slot power supply designed for HP ProLiant Gen8 servers. It delivers 48VDC output through a hot-pluggable form factor that fits directly into the server chassis. The unit weighs 4.0 pound and carries a 1 year warranty. It replaces part numbers 636673-B21, 639173-001 and 619671-001.

For Gen8 server maintenance

This module suits administrators replacing a failed unit or adding redundancy to an existing Gen8 configuration that uses the Common Slot bay. It is not for builders assembling new systems outside the Gen8 platform or for racks requiring a different voltage input or wattage rating. Buyers needing AC-input or higher-capacity supplies should look elsewhere.

48VDC Common Slot interface

The single specification that determines compatibility is the 48VDC Common Slot interface. Only servers equipped with this exact bay architecture and voltage domain can accept the module. Verify the server model supports the Common Slot 48VDC design before purchase.

Questions about this item

How do I confirm the HSTNS-PF04 is running correctly after installing it in a ProLiant Gen8 server?

The server's iLO or front-panel health LEDs will show the 750W module as present and OK once it seats in the Common Slot backplane and receives 48VDC.

What ships with the HSTNS-PF04 and what must I source separately?

Only the 750W Common Slot power module is supplied; any AC power cords, DC source cables or rack mounting hardware are separate purchases.

Which part numbers identify the correct 750W 48VDC Common Slot supply for my Gen8 server?

Look for HP part numbers 636673-B21, 639173-001 or 619671-001 — all reference the same HSTNS-PF04 750W 48VDC module.
