Lenovo 4XH7A87511 SR650 V3 Single CPU GEN5 RISER3 KIT

Lenovo 4XH7A87511 SR650 V3 Single CPU Gen5 Riser 3 Kit

Overview

The Lenovo 4XH7A87511 is a PCIe Gen5 riser card kit designed for single-CPU configurations of the ThinkSystem SR650 V3 rack server. Riser 3 occupies the third PCIe expansion slot position in the SR650 V3 chassis — relevant when you need to maximize PCIe expansion without a second processor installed. At 2.00 lb, the kit ships factory-new from Lenovo's manufacturing supply chain (Country of Origin: MX) and installs directly into the SR650 V3 tool-assisted slot assembly.

Compatibility

Designed exclusively for the Lenovo ThinkSystem SR650 V3 in single-CPU (1S) configuration. This riser is specific to the SR650 V3 platform — it is not interchangeable with SR650 V2 or other ThinkSystem rack server generations. Verify your SR650 V3 chassis configuration and existing riser population before ordering; the Gen5 slot assignment and physical bracket geometry are platform-specific and will not seat correctly in prior SR650 revisions.

Installation Notes

Install into the Riser 3 position with the server powered down and chassis opened per Lenovo's SR650 V3 maintenance guide. Single-CPU SR650 V3 systems require CPU socket 1 populated; Riser 3 availability depends on your chassis SKU and existing riser configuration — confirm slot 3 is unpopulated and the corresponding bracket cutout is present before installation.
