Lenovo 4M17A13565 SR250 3.5 4-BAY BP Cable KIT

Lenovo 4M17A13565 SR250 3.5" 4-Bay Backplane Cable Kit

Overview

The Lenovo 4M17A13565 is a factory-new backplane cable kit designed specifically for the ThinkSystem SR250 server configured with a 3.5-inch 4-bay drive cage. If you're wiring up or replacing the storage interconnect on an SR250 chassis, this is the correct cable assembly — it provides the point-to-point connections between the drive backplane and the system board without requiring you to source individual cables separately. Having the right kit at hand prevents configuration delays when commissioning a replacement backplane or recovering from a damaged cable run during a drive expansion.

Compatibility

This kit is designed for the Lenovo ThinkSystem SR250 server platform in the 3.5-inch 4-bay storage configuration. It is not cross-compatible with the 2.5-inch bay variants or with higher bay-count (8-bay) SR250 configurations, nor with other ThinkSystem models such as the SR150 or SR350. Confirm your SR250's drive bay type and count before ordering — the backplane connector layout differs between 3.5-inch and 2.5-inch chassis builds. If you are sourcing parts for a network video recorder build or a similar storage-dense server application, verify the SR250 variant in your rack against Lenovo's chassis configuration guide.

Installation Notes

Route cables according to the SR250 hardware maintenance manual to avoid pinch points near the fan assembly and ensure adequate airflow is not obstructed. Seat backplane connectors fully before securing the chassis — a partial connection on the backplane side is a common source of drive non-detection on first boot. Weight is 1.55 lb; dimensions are 19.60 × 6.90 × 5.40 in, so confirm clearance in tight rack configurations before installation. For enterprise deployments pairing the SR250 with PoE network switches or external NVR storage, ensure server-side cabling is completed before rack dress-out. Consult the server accessories category for complementary SR250 components.
