Lenovo 4XH7B08910 SR860 V4 G5 Riser 3X16 2X8 + M.2

Lenovo 4XH7B08910 SR860 V4 G5 Riser Card — 3x16 2x8 PCIe + M.2

Overview

The Lenovo 4XH7B08910 is a riser card assembly designed for the ThinkSystem SR860 V4 server platform, expanding available PCIe connectivity with three x16 slots, two x8 slots, and an M.2 interface. When a high-density GPU, NIC, or storage expansion deployment demands more PCIe bandwidth than the base configuration provides, the 4XH7B08910 fills that gap without requiring an external expansion chassis. The M.2 form factor support adds a path for fast NVMe boot or caching drives directly on the riser, keeping cable runs short and the chassis interior clean.

Compatibility

This riser is designed specifically for the Lenovo ThinkSystem SR860 V4 (Generation 5) platform. It is not a universal riser — slot geometry, signaling, and firmware initialization are matched to the SR860 V4 chassis. Confirm your server's chassis generation and riser bay designation before ordering; the SR860 V4 supports multiple riser positions and not every bay accepts this card. Cross-reference Lenovo's configuration tools or your server's Hardware Maintenance Manual to verify the correct riser slot assignment for your specific SR860 V4 build. For related server expansion components, verify PCIe generation compatibility with your installed processors before populating high-lane-count adapters across all five slots simultaneously.

Installation Notes

Weight is 10.00 lb — account for this during chassis handling, particularly when the riser is fully populated with adapters. Country of origin is Mexico. Installation follows standard Lenovo tool-less riser seating procedures for the SR860 V4; consult the server's Hardware Maintenance Manual for torque specifications on any retention screws and for the correct card-population sequence when mixing x16 and x8 adapters. M.2 drive installation requires appropriate standoff hardware matched to the drive length — verify drive form factor compatibility before ordering M.2 storage.
