Lenovo 4C57A15004 SR860 V2 2U Riser

Lenovo 4C57A15004 SR860 V2 2U Riser

Overview

The Lenovo 4C57A15004 is a 2U riser designed for use with Lenovo ThinkSystem SR860 V2 rack servers. Riser cards in this form factor serve a specific structural and electrical purpose: they reorient PCIe slots to accommodate add-in cards within the constrained depth of a 2U chassis. If you're expanding I/O capacity — adding HBAs, NICs, or GPUs to an SR860 V2 — this riser is the mechanical and electrical interface that makes it possible without external cabling or adapter workarounds. The 4C57A15004 ships as a factory-new, genuine Lenovo component sourced through the distribution channel.

Compatibility

This riser is designed specifically for the Lenovo ThinkSystem SR860 V2 platform. The SR860 V2 is a 4-socket 2U server targeting high-density compute, in-memory database, and virtualization workloads. Confirm your SR860 V2 configuration and riser bay assignment against Lenovo's SR860 V2 configuration guide before ordering — the SR860 V2 supports multiple riser positions, and the correct riser part number depends on which bay you're populating and which PCIe add-in cards you intend to install. Do not assume cross-compatibility with SR860 V1 or other ThinkSystem 2U platforms (SR650, SR850) without verifying against Lenovo's published compatibility matrix for your specific chassis revision.

Installation Notes

At 60 lb shipping weight, this component ships with protective packaging appropriate for server-grade hardware — verify the carton is undamaged before acceptance. Installation requires powering down the SR860 V2 and following Lenovo's ESD precautions. Seat the riser card firmly into the system board riser connector and secure it with the chassis retention hardware. Consult the SR860 V2 server components maintenance manual for torque specifications and slot-population rules before installing any add-in cards into the riser.
