Lenovo 4X97A82944 SR650 V3 2ND CPU GEN4 RISER3 CBL

Lenovo 4X97A82944 SR650 V3 2nd CPU Gen4 Riser 3 Cable

Overview

The Lenovo 4X97A82944 is a Gen4 Riser 3 cable assembly designed for dual-processor configurations in the ThinkSystem SR650 V3 rack server. When you add a second CPU to an SR650 V3, the riser 3 slot becomes active — this cable is the physical interconnect that brings it online. Without it, the second processor and any PCIe devices seated in Riser 3 remain non-functional regardless of how the rest of the system is configured. This is a factory-new, genuine Lenovo component sourced through channel-direct distribution.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 in dual-CPU (2nd CPU populated) configurations. Riser 3 is only relevant when the second processor socket is occupied — this cable is not required in single-CPU builds. Verify your SR650 V3 chassis revision and riser configuration before ordering, as riser cabling varies across SR650 generations (SR650 V2 and original SR650 use different assemblies and are not compatible with this part). If you are sourcing cables for a server expansion project, confirm the riser bay assignment in your system's Hardware Maintenance Manual to ensure 4X97A82944 maps to your specific Riser 3 slot position.
