HP 409858-001 Redundant Power Supply

The HP 409858-001 is a redundant hot-swap power supply designed for compatible enterprise server chassis. It accepts 100-240V AC input at 3A, allowing deployment across global voltage standards without manual switching. This unit targets IT administrators who need to maintain uptime during hardware maintenance. Builders requiring a non-redundant desktop PSU or a different form factor should look elsewhere.

Hot-Swap Sustained Operation

Hot-swap capability lets technicians replace this module while the system continues running, eliminating downtime during a failure event. Redundant architecture shares the load across multiple units so no single supply operates at its thermal limit continuously. The wide 100-240V AC range maintains stable output during prolonged brownouts or generator transfers. Environments that cannot schedule maintenance windows gain continuous power protection.

Highlights

  • Redundant design keeps servers running during a unit failure
  • Hot-swap capability allows replacement without powering down
  • Wide 100-240V AC input suits global power environments
  • New condition ensures full factory reliability from first use
