Lenovo 4X97B05125 Thinksystem Signal Cable 1 for RAID 4450/5450/9450-8/16I 8GB Adapter to 8X2.5INC

Lenovo 4X97B05125 ThinkSystem Signal Cable for RAID Adapter to 2.5" Drive Bay

Overview

The Lenovo 4X97B05125 is a signal cable designed to bridge ThinkSystem RAID adapters — specifically the 4450, 5450, 9450-8i, and 9450-16i series with 8GB cache — to 8-bay 2.5-inch drive backplanes. If you are wiring a ThinkSystem server for SAS/SATA storage expansion and need the physical interconnect between the RAID card and the drive cage, this is the cable that completes that path. Without the correct signal cable, the RAID adapter cannot address the attached drives — selecting the right part number up front avoids a return loop during server commissioning.

Compatibility

The 4X97B05125 is specified for use with the following Lenovo ThinkSystem RAID adapters: the Lenovo ThinkSystem RAID 4450-8i, RAID 5450-8i, RAID 9450-8i, and RAID 9450-16i, all in the 8GB flash-backed cache configuration. The drive-side connection targets an 8-bay 2.5-inch hot-swap backplane. Verify your specific ThinkSystem server model's hardware maintenance manual to confirm backplane connector placement and cable routing clearance before ordering — ThinkSystem 2U and 4U chassis vary in bay-to-adapter cable length requirements. For full storage infrastructure builds, cross-reference the server's component compatibility matrix to ensure the RAID adapter generation matches this cable revision.

Installation Notes

Route the cable after seating the RAID adapter in its PCIe slot and before final drive population — cable bulk in a fully loaded 2.5-inch bay configuration can restrict airflow if dressed incorrectly. Secure any excess cable length with provided tie points in the chassis to prevent contact with fans or heatsinks. No special tooling is required for connector seating; connectors are keyed and click into place. Country of origin is Mexico.
