Lenovo 4X97A86422 SR655 V3 3.5IN M SAS CA KIT

Lenovo 4X97A86422 SR655 V3 3.5-Inch Midplane SAS Cable Kit

Overview

The Lenovo 4X97A86422 is a SAS cable kit designed for the ThinkSystem SR655 V3 rack server in 3.5-inch midplane (M) drive configurations. If you are expanding or replacing the internal SAS cabling path between the backplane and the storage controller in an SR655 V3, this is the correct kit — using the wrong cable assembly means incompatible connectors, incorrect routing, or no signal continuity to the drive array. At 10 lb, this is a multi-cable assembly, not a single patch cable.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR655 V3 server platform in the 3.5-inch midplane bay configuration. The SR655 V3 ships in multiple backplane and drive-bay layouts; confirm your chassis populates the 3.5-inch midplane option before ordering — the 2.5-inch and direct-attach variants require different cable kits. This kit is not cross-compatible with SR655 (Gen 1/V2), SR650, or other ThinkSystem chassis generations, which use distinct backplane connector layouts and routing paths. Verify your server hardware build sheet or Field Replaceable Unit (FRU) list against part number 4X97A86422 before procurement.

Installation Notes

SAS cable replacement in the SR655 V3 requires powering down the system and following Lenovo's electrostatic discharge (ESD) procedures — SAS signal cables are sensitive to connector seating; partial engagement produces intermittent drive errors that are difficult to distinguish from drive failure. Route cables per the SR655 V3 Hardware Maintenance Guide to avoid pinch points against the chassis wall or obstructing airflow baffles. Country of origin is Mexico (MX); UNSPSC code 43211600 classifies this as a computer storage device cable/interconnect component.
