Lenovo 4XH7B03718 PCIe Gen5 x8 Cable Riser for ThinkSystem SR650 V4

Overview

The 4XH7B03718 is a PCIe Gen5 x8 cable riser option kit designed for the Lenovo ThinkSystem SR650 V4 server, specifically enabling PCIe expansion at slots 1, 2, 9, and 10. If your SR650 V4 configuration requires additional high-bandwidth PCIe Gen5 cards in those positions — GPU accelerators, high-speed NICs, NVMe over Fabrics HBAs, or storage controllers — this riser provides the physical and electrical interconnect that makes it possible. Without it, those expansion slots are inaccessible regardless of what adapter cards you have on hand. At 1.00 lb, it ships factory-new and is sourced directly through authorized distribution channels.

Compatibility

This riser kit is designed specifically for the Lenovo ThinkSystem SR650 V4 rack server. It is not interchangeable with earlier SR650 generations (V2, V3) or other ThinkSystem platforms such as the SR630 V4 or SR850 V4 — PCIe riser assemblies are chassis- and generation-specific. Before ordering, confirm your SR650 V4 chassis configuration supports the x8 Gen5 cable riser variant at slots 1/2/9/10, as Lenovo offers multiple riser options depending on the chassis bay layout and existing installed risers. Cross-reference with the SR650 V4 server option compatibility matrix or your system's Configuration and Options Guide to verify this is the correct riser for your slot assignment.

Installation Notes

Installation requires access to the SR650 V4 interior with the server powered down and removed from its rack position. The cable riser seats into the designated riser cage location and routes the PCIe Gen5 x8 signal via the integrated cable assembly — no additional cabling is required beyond what the kit provides. Gen5 riser connectors are keyed and generation-specific; do not force-fit into Gen4 riser slots. Follow Lenovo's SR650 V4 Hardware Maintenance Guide for torque and seating procedures. Country of origin is Mexico.
