Lenovo 4C57A15003 SR860 V2 2U Riser

Lenovo 4C57A15003 SR860 V2 2U Riser

Overview

The Lenovo 4C57A15003 is a 2U riser assembly designed for the ThinkSystem SR860 V2 server platform. It provides the mechanical and electrical interface needed to extend PCIe slot availability within the 2U chassis — a necessary component when expanding I/O capacity for additional network, storage, or accelerator cards in dense rack deployments. If you're configuring or reconfiguring an SR860 V2 with a riser slot that was not populated at factory, the 4C57A15003 is the compatible field-installable part.

Compatibility

This riser is designed specifically for the Lenovo ThinkSystem SR860 V2 2U rack server. It is not a universal riser — verify your SR860 V2 chassis bay designation and riser configuration order before purchasing. Compatibility with other ThinkSystem generations (SR860 Gen 1, SR850, SR950) is not confirmed by available evidence and should be verified against Lenovo's official configurator or service documentation prior to ordering. For server expansion planning in data center servers, confirm the target slot and any co-requisite hardware with your Lenovo service documentation.

Installation Notes

Classified under UNSPSC 43211600 (computer servers and workstations). At 60 lb, this component's listed weight likely reflects the shipping package rather than the riser card itself — handle and verify actual component weight per Lenovo's service documentation before rack work. Follow Lenovo's ThinkSystem SR860 V2 server rack accessory installation procedures: power down and discharge the server fully before accessing riser slots, observe ESD precautions, and confirm slot seating is secure before powering on. No torque specifications or additional tooling requirements are available in current evidence.
