HPE P79842-B21 -48VDC Hardwire Power Cord
Overview
The HPE P79842-B21 is a -48VDC hardwire power cord rated 1000–1300W, 3.5m in length. This accessory delivers DC power directly into HPE infrastructure equipment that requires a hardwired connection from a rectified power source — common in carrier-grade telecom, data center UPS bypass, and surveillance power distribution architectures where DC is distributed centrally rather than via AC branch circuits.
Compatibility
This cord connects HPE power supplies and DC-input systems in enterprise surveillance and network infrastructure deployments. Compatibility is limited to HPE equipment with -48VDC hardwire input specifications. Confirm the exact connector type and mating interface on your HPE device before purchase — different HPE product lines use different hardwire connector standards.
Installation Notes
The 3.5m length accommodates standard rack-to-cabinet or UPS-to-equipment runs in 19-inch environments. Ensure the source rectifier or power supply is rated for continuous 1000–1300W output and properly isolated. Hardwire DC circuits require correct polarity — verify your distribution panel's negative and positive terminal assignments before making final connections. Do not exceed the specified wattage or mix connectors from different equipment families.
