Lenovo 4XH7A96826 SR630 V4 X16/X16 G5 Cable Riser 1 FH+LP

Overview

The Lenovo 4XH7A96826 is a PCIe Gen 5 cable riser card designed for the ThinkSystem SR630 V4 rack server. It provides dual X16 PCIe Gen 5 slots in a Riser 1 position, supporting both full-height (FH) and low-profile (LP) add-in cards — giving system architects the flexibility to mix card form factors within a single riser assembly. If you're expanding an SR630 V4 with high-bandwidth PCIe Gen 5 adapters (networking, storage controllers, or GPU accelerators) and need to preserve the Riser 1 slot configuration, this is the correct part to source.

Compatibility

This riser is specifically engineered for the Lenovo ThinkSystem SR630 V4 platform. It is not cross-compatible with earlier SR630 generations (SR630 V2, SR630 V3) or other ThinkSystem models — PCIe riser assemblies are platform-specific due to differing backplane connectors, chassis geometry, and riser bracket profiles. Verify your server's chassis generation and existing riser configuration before ordering. If your SR630 V4 deployment includes PCIe expansion cards requiring full X16 Gen 5 bandwidth — such as 200GbE adapters or NVMe storage controllers — this riser delivers the lane width and signaling speed those cards require without a bandwidth bottleneck at the riser interface.

Installation Notes

The 4XH7A96826 installs into the Riser 1 bay of the SR630 V4 chassis. Installation requires powering down the server and following Lenovo's ESD precautions for server-grade components. Consult the ThinkSystem SR630 V4 hardware maintenance manual for the correct riser seating sequence and cable routing — improper installation of PCIe Gen 5 risers can result in signal integrity issues at high lane speeds. Weight of the assembly is 1.00 lb. No additional tools beyond standard server maintenance equipment are required, but confirm cable routing clearance within the chassis before finalizing the add-in card selection, particularly for full-height cards adjacent to airflow baffles.
