Lenovo 4M17A80607 SR250 3.5 S&S 4-BAY BP X40 CBL KIT V2

Lenovo 4M17A80607 SR250 3.5-Inch 4-Bay Backplane Cable Kit V2

Overview

The Lenovo 4M17A80607 is the V2 revision of the 3.5-inch Simple-Swap (S&S) 4-bay backplane X40 cable kit for the ThinkSystem SR250 server. This kit supplies the signal and power cabling infrastructure between the drive backplane and the system board — the missing link when adding or replacing a backplane assembly in an SR250 chassis. Without it, installed drives will not communicate with the controller, making this a required component for any SR250 storage expansion or backplane swap that doesn't include cabling in the base configuration.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR250 1U rack server configured with the 3.5-inch Simple-Swap 4-bay drive cage. The X40 designation ties this cable kit to the SR250's internal storage controller interface — it is not interchangeable with SAS/SATA backplane cable kits from other SR250 bay configurations (such as 2.5-inch or hot-swap variants). Verify your SR250's bay type and backplane model before ordering; mixing Simple-Swap and Hot-Swap cable kits will result in a physical mismatch. For broader server accessories compatibility across the ThinkSystem line, confirm the chassis generation against Lenovo's configurator.

Installation Notes

Route cables according to the SR250 hardware maintenance manual — cable management in a 1U chassis is tight, and improper routing risks pinching against drive trays or blocking airflow. The V2 revision may have connector or routing changes versus V1; do not substitute V1 cables in a V2-configured system. At 10 lb, the kit weight reflects bundled hardware — handle the backplane assembly carefully during installation to avoid connector damage.
