The HPE 2650W HVDC Hot-Plug Power Supply Kit (798342-B21) is a high-efficiency, 2650-watt DC server power module designed for HPE blade and rack servers, enabling nonstop operation through hot-swappable redundancy.
The 798342-B21 kit is compatible with HPE c-Class blade enclosures (C7000, C3000) and select ProLiant DL server series that support high-voltage direct current (HVDC) power modules.
To install, align the module with the server’s power bay, slide it firmly until it clicks, and verify LED indicators turn green; no shutdown is required due to hot-plug capability.
The 798342-B21 power supply requires an HVDC input between 380V and 400V, delivering up to 2650W to the server’s internal power distribution system.
No, HPE enclosures must use uniform power supply types; mixing HVDC and AC modules in the same chassis is not supported.
The 798342-B21 supports N+1 and N+N redundancy configurations, ensuring continuous server operation if one module fails or is removed.
Monitor the integrated LED display and use HPE iLO or Onboard Administrator for real-time power metrics, temperature, and fault alerts.
The 798342-B21 is UL, CE, and TUV certified, meeting global safety and electromagnetic compatibility (EMC) standards for data center environments.
Yes, the 2650W HVDC module features built-in electronic overload protection, automatically throttling or shutting down to prevent damage under excess load.
This HVDC power kit operates at up to 96% efficiency under typical data center loads, reducing energy waste and cooling costs.
HPE provides a three-year limited warranty on the 2650W HVDC hot-plug power supply, with optional extension available via HPE Care Pack services.
Order genuine HPE spares through authorized HPE Partners or directly via the HPE Parts Store using SKU 798342-B21 for accurate procurement.
Yes, the hot-plug design allows safe removal and replacement of the 2650W HVDC module without interrupting server operations, provided redundancy is active.
The module measures 219 mm x 87 mm x 41 mm (8.6″ x 3.4″ x 1.6″) and weighs approximately 1.2 kg (2.6 lbs), fitting standard HPE power bays.
HVDC reduces conversion losses, improves overall system efficiency, and lowers cooling requirements, delivering cost savings and higher power density.
Operate at 10–35°C (50–95°F), 5–85% relative humidity (non-condensing), and an altitude up to 3,000 meters to ensure compliance with HPE data center guidelines.
