Lenovo 4XH7A86662 SR650 V3 PCIE G5 Riser 3/4 Option KIT

Lenovo 4XH7A86662 SR650 V3 PCIe Gen5 Riser 3/4 Option Kit

Overview

The 4XH7A86662 is a PCIe Gen5 Riser 3/4 Option Kit designed to expand the PCIe slot capacity of the ThinkSystem SR650 V3 server. If your SR650 V3 build is running short on PCIe expansion slots — whether for additional NIC cards, HBAs, GPU accelerators, or storage controllers — this riser kit provides the mechanical and electrical infrastructure to add those slots without chassis modification. At 10 lb, the assembly is a substantial mechanical kit; plan for two-person handling during installation in a populated rack.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 rack server. The SR650 V3 platform supports multiple riser configurations, and this kit occupies the Riser 3/4 position — verify your existing riser population and chassis revision against Lenovo's SR650 V3 configuration guide before ordering to avoid slot conflicts. This kit is not compatible with the SR650 V2 or earlier SR650 generations, which use different riser form factors and backplane connectors. If you are sourcing expansion options for other server platforms, confirm the riser position and PCIe generation match your chassis bill of materials.

Installation Notes

Installation requires powering down and removing the SR650 V3 from service. The PCIe Gen5 interface demands careful seating — partial engagement will prevent POST or cause lane negotiation errors. Review Lenovo's SR650 V3 Hardware Maintenance Guide for the correct riser cage alignment procedure and torque specifications before installing any cards into the populated riser. Country of origin is Mexico.
