HPE - 0957-2139 - HPE 875W zl Power Supply

The HPE 0957-2139 is an 875W zl power supply designed for HPE’s modular zl switching platforms, providing the power headroom required for populated chassis configurations and 24/7 enterprise operation. It is a practical choice for maintaining consistent power delivery in wiring closets and campus networks where chassis-based switching is used.

This unit is typically deployed as a replacement or spare PSU to keep installed HPE zl systems running without changing the existing chassis and module configuration. For broader lifecycle support across your installed base, Direct Hardware Supply also stocks related infrastructure across HPE portfolios, including components used in RACK SERVER environments and selected BLADE SERVER platforms.

Key Features

Key technical characteristics for integration and maintenance planning:

• 875W “zl” power supply form factor to match HPE zl chassis power bays for correct mechanical and electrical fit.
• Compatible with HPE ProCurve/Aruba chassis-based zl switches to support ongoing operation and spares strategy (e.g., Switch 5400zl family and Switch 8212zl chassis).
• Designed for modular switch deployments to power installed line modules and uplink modules within a zl chassis.
• Enterprise-grade power design to support continuous 24/7 operation in campus and wiring-closet installations.
• Replacement PSU role to restore a chassis after PSU failure and reduce unplanned downtime during maintenance windows.
• Supports standard chassis power redundancy concepts (when used alongside additional PSUs where the chassis design allows) to improve resilience.
• HPE part number 0957-2139 identification to help match BOMs and maintenance documentation for accurate ordering.
• Service-friendly swap approach for field maintenance to keep existing chassis, modules, and cabling in place.

Refurbished Quality and Warranty

This is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished spares are a practical way to extend the lifecycle of installed switching infrastructure, control budget compared to buying new, and reduce electronic waste.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. If you are aligning power-related maintenance with platform refresh planning, you may also source complementary parts such as SYSTEM BOARD components for supported HPE systems.
