Lenovo 4XH7B08911 SR860 V4 G5 Riser 6X8

Lenovo 4XH7B08911 SR860 V4 G5 Riser 6X8

Overview

The 4XH7B08911 is a PCIe riser card designed to expand slot capacity in Lenovo ThinkSystem SR860 V4 servers. Riser assemblies like this one are required when deploying high-density workloads that demand more PCIe devices than the base configuration provides — think additional network adapters, HBAs, or GPU accelerators in a single chassis. The G5 designation and 6X8 label indicate the riser's generation compatibility and slot configuration, making it a targeted fit for SR860 V4 builds that need the full complement of expansion lanes. If you're configuring an SR860 V4 for a compute-intensive or storage-heavy deployment, the correct riser selection is a prerequisite — installing the wrong generation riser prevents proper seating and can leave PCIe lanes unrouted.

Compatibility

This riser is specifically designed for the Lenovo ThinkSystem SR860 V4 platform. The G5 riser family is not interchangeable with SR860 V2 or V3 generation risers — connector keying and backplane routing differ between generations. Verify your SR860 V4's current riser configuration against Lenovo's build documentation before ordering; the SR860 V4 supports multiple riser positions and configurations, and 4XH7B08911 targets a specific slot assignment within that chassis. Pairing this with incompatible riser positions or a prior-generation SR860 will result in a non-functional configuration. For full server infrastructure planning, review your rack server expansion requirements before finalizing the BOM.

Installation Notes

Country of origin is Mexico. Weight is 10.00 lb — account for this when planning chassis balance in rack enclosures, particularly in fully populated 4-socket SR860 V4 configurations where multiple risers, drives, and dual PSUs are installed simultaneously. Follow Lenovo's ThinkSystem SR860 V4 Maintenance Manual for proper riser seating sequence and torque requirements; incorrect installation order can stress the riser connector. No additional tools beyond standard server deployment kit are indicated by available documentation.
