Lenovo 4XH7B08907 SR860 V4 G4 Riser M.2/X8/X8

Lenovo 4XH7B08907 SR860 V4 G4 Riser M.2/x8/x8

Overview

The Lenovo 4XH7B08907 is a riser card assembly for the ThinkSystem SR860 V4 platform, providing an M.2 slot combined with two x8 PCIe Gen 4 slots in a single module. This riser targets builds that need additional NVMe boot or caching storage via M.2 alongside two additional PCIe expansion slots — a common configuration need in dense compute or storage-heavy server deployments where the base riser population leaves GPU, HBA, or NIC slots short.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR860 V4 server platform. This riser is not interchangeable across other ThinkSystem generations or form factors — confirm your chassis is the SR860 V4 before ordering, as riser slot assignments and PCIe lane routing are chassis-specific. Consult the SR860 V4 server accessory configuration guide to verify riser bay position and slot compatibility with your planned adapter cards.

Installation Notes

Manufactured in Mexico; ships at 10.00 lb — account for packaging weight when planning rack-delivery logistics. Installation follows standard Lenovo ThinkSystem riser swap procedure: power down and disconnect the server, remove the existing riser assembly from its designated bay, seat the 4XH7B08907 into the connector, and secure per the chassis mechanical guide. M.2 devices install into the onboard slot before inserting the riser into the chassis. Verify PCIe bifurcation settings in UEFI match the populated adapter configuration after installation.
