Lenovo 4XH7A87546 SR655 V3 X8/X8 G4 R3 LP KIT

Lenovo 4XH7A87546 SR655 V3 X8/X8 G4 R3 Low-Profile Riser Kit

Overview

The Lenovo 4XH7A87546 is a dual X8 Gen 4 Riser 3 low-profile (LP) kit designed for the ThinkSystem SR655 V3 server platform. If you're expanding PCIe capacity in an SR655 V3 chassis — adding a second NIC, a storage HBA, or a low-profile GPU — this riser kit provides the Riser 3 slot position with two X8 Gen 4 connections. It ships factory-new from Mexico (country of origin: MX) and is a genuine Lenovo server option, not a third-party aftermarket part.

Compatibility

This kit is engineered specifically for the Lenovo ThinkSystem SR655 V3 rack server. It is not cross-compatible with SR655 V2, SR645, or other ThinkSystem platforms — the mechanical bracket profile, backplane connector, and Gen 4 signaling are specific to the V3 chassis revision. Before ordering, confirm your SR655 V3 configuration supports a third riser position and that your target PCIe cards are low-profile form factor. High-profile or full-height cards will not fit this kit.

Installation Notes

Installation follows standard Lenovo server accessory procedures for the SR655 V3. The kit occupies the Riser 3 slot; consult the SR655 V3 maintenance manual to verify slot population rules and any firmware dependencies before seating cards. The 10 lb shipping weight reflects the full kit assembly — handle with standard ESD precautions. No additional tools beyond a standard screwdriver are typically required, but confirm torque specifications in the Lenovo Hardware Maintenance Guide for your specific chassis revision.
