Lenovo 4M17A12095 ST50 Dual SD Cards Adapter KIT

Lenovo 4M17A12095 Dual SD Cards Adapter Kit

Overview

The Lenovo 4M17A12095 is a dual SD card adapter kit designed for internal SD-based storage expansion in compatible Lenovo ThinkSystem servers. It provides a structured mounting solution for two SD cards within the chassis, addressing deployments where administrators need redundant or supplemental flash-based storage for OS booting, hypervisor hosting, or persistent logging — without consuming a drive bay. The 4M17A12095 ships as a kit, keeping the installation self-contained and field-ready.

Compatibility

This adapter kit is designed for the Lenovo ThinkSystem ST50 tower server. Verify your specific ST50 configuration and system board revision against Lenovo's compatibility matrix before ordering — SD adapter support can vary by board stepping and firmware level. It is not a universal SD adapter; do not assume cross-compatibility with other ThinkSystem tower or rack models (ST250, ST550, SR series) without confirmed documentation. For broader server storage accessories, confirm the target platform first.

Installation Notes

The adapter kit mounts internally within the ST50 chassis. Ensure the system is fully powered down and grounded before installation — SD card adapters interface directly with the system board header, which is sensitive to static discharge. SD cards are not included; source cards rated for continuous server workloads (industrial-grade or server-class SLC/MLC NAND), as consumer-grade cards are not engineered for the sustained read/write cycles of a always-on server environment. Consult the ST50 Hardware Maintenance Manual for the exact connector location and any torque or retention clip requirements specific to your chassis revision.
