HPE 1600W FS -48VDC HT PLG PS KIT - P17023-B21

HPE P17023-B21 1600W FS -48VDC Hot-Plug Power Supply Kit

Overview

The HPE P17023-B21 is a 1600W fully redundant (FS), -48VDC hot-plug power supply kit designed for HPE server platforms that operate on negative 48V DC infrastructure — common in telecom co-location environments, carrier-grade data centers, and facilities where DC power distribution is the backbone rather than AC. Hot-plug capability means P17023-B21 units can be swapped under load without taking the host server offline, which matters in high-availability deployments where scheduled downtime is not acceptable.

Compatibility

The P17023-B21 is an HPE option kit specific to server platforms that support the -48VDC power input form factor within the HPE server and infrastructure line. Verify your target server power supply bay configuration against the HPE QuickSpecs for your specific ProLiant or Synergy platform before ordering — not all HPE server generations or chassis configurations support -48VDC input, and this unit is not interchangeable with standard AC hot-plug supplies. Cross-reference the HPE Power Advisor tool or your platform's QuickSpecs document to confirm slot compatibility, DC bus voltage requirements, and maximum PSU count per chassis.

Installation Notes

DC power supply installations require a qualified electrician familiar with -48VDC bus wiring, polarity, and grounding practices — incorrect polarity will damage both the supply and the host platform. Ensure your facility's DC plant delivers stable -48VDC within the input voltage tolerance specified for this unit. The hot-plug design requires the chassis power bus to be active and within spec before inserting the supply; always follow HPE's documented PSU insertion sequence for your specific server model. Confirm your rack power distribution and DC bus capacity can support the 1600W draw under full server load.
