Lenovo Cable & Flash Mechanism Kit

The Lenovo 4Z57A80611 is a purpose built cable and flash mechanism kit engineered for ThinkSystem ST250 servers that rely on X40-series RAID or HBA adapters. It provides the physical link and power protection that these adapters need to keep data moving and cached information safe when the unexpected happens.

Inside the kit you will find a Slimline-SAS cable that connects the server’s internal drives to the X40 RAID controller or host bus adapter, creating a pathway that helps maintain consistent throughput. A dedicated battery holder is also included; it secures the flash module so write-back cache can survive a power interruption and be written to disk once normal operation resumes.

This kit becomes essential when you are configuring a new ST250 with X40 storage options or upgrading an existing system to add more drives. Administrators who run file services, virtualization workloads, or branch office applications will appreciate the added layer of data integrity it brings. By combining the correct cable with a stable flash mounting solution, the kit minimizes installation time and ensures the server meets Lenovo’s best-practice design for X40 RAID/HBA deployments.

Because it is designed and supported by Lenovo, the 4Z57A80611 integrates cleanly with ThinkSystem management tools and service procedures, making it a dependable choice for IT teams that value predictable performance and straightforward maintenance in compact tower server environments.
