Description

Lenovo 4X97A78621 Internal Drive Cable Kit

Overview

The Lenovo 4X97A78621 is a factory-new internal drive cable kit designed for direct installation into compatible Lenovo ThinkSystem tower servers. When expanding or reconfiguring storage inside a server — adding drives, replacing a failed cable assembly, or completing a build-to-order configuration — having the correct OEM cable kit means connectors seat properly and signal integrity is maintained across the backplane. Using off-brand or mismatched cables in a server platform risks intermittent drive errors, voided service agreements, and troubleshooting time that outweighs any cost savings. The 4X97A78621 eliminates that risk by providing the exact assembly Lenovo specifies for the platform.

Compatibility

This cable kit is designed for the Lenovo ThinkSystem ST50 V2 tower server. Verify your specific server model and storage configuration against Lenovo's options guide before ordering — ST50 V2 drive cable requirements vary depending on installed drive bays and backplane type. This kit is not a universal fit across the broader server accessory catalog; confirm the ST50 V2 platform before purchase. If you are outfitting an ST50 (non-V2) or a different ThinkSystem tower such as the ST250 or ST650, a different cable assembly applies.

Installation Notes

Installation is performed inside the ST50 V2 chassis with the server powered off and unplugged. Route cables per Lenovo's internal cabling guide for the ST50 V2 to avoid airflow obstruction and interference with the system board. The kit ships at 0.35 lb and fits within a 9.60 × 6.00 × 2.20 in envelope — consistent with a multi-connector cable assembly. No special tooling beyond standard server screwdrivers is typically required, but consult the ST50 V2 maintenance manual for connector seating torque and any backplane-specific fitment notes before beginning.
