Lenovo 4XH7A61123 SR655 3.5 Sas/sata 12-BAY X40 CBL KIT

Lenovo 4XH7A61123 SR655 3.5" 12-Bay SAS/SATA Cable Kit

Overview

The Lenovo 4XH7A61123 is a factory-new cable kit designed to wire the 12-bay 3.5" SAS/SATA backplane in the ThinkSystem SR655 server for X40-class storage controller configurations. If you're expanding storage capacity in an SR655 chassis or replacing damaged signal cabling between the backplane and HBA, this kit delivers the correct cable geometry and connector spec for a clean, supported installation — without sourcing generic alternatives that may not seat properly or meet the backplane's signal-integrity requirements. Weight is 10 lb, consistent with a multi-cable assembly for a fully populated 12-bay configuration.

Compatibility

This kit is designed for the Lenovo ThinkSystem SR655 server platform, specifically the 3.5" 12-bay SAS/SATA backplane variant paired with an X40-series storage controller. It supports both SAS and SATA drive interfaces, making it suitable for mixed-drive deployments — SAS spinning media, SAS SSDs, or SATA SSDs — within the same backplane. If your SR655 is configured with a different backplane count (8-bay or 24-bay) or a different controller generation, verify the correct cable kit part number before ordering, as cable length and connector positions vary by chassis configuration. This kit is not intended for NVR storage appliances or non-Lenovo server platforms.

Installation Notes

Route cables per Lenovo's SR655 hardware maintenance guide to avoid pinch points near the chassis fan wall and CPU heatsinks. SAS/SATA signal cables are keyed — verify connector orientation before seating to avoid bent pins on the backplane header. With a 10 lb kit weight, handle the cable assembly carefully during routing to prevent connector stress. Confirm the X40 controller is fully seated in its PCIe slot before connecting the cable ends, as partial seating can cause intermittent drive detection failures post-boot.
