How to install Lenovo ThinkSystem ST250 3.5" SATA/SAS 4-Bay Backplane Kit

• Prepare the server: Power down the ST250, unplug all cables, and discharge any residual static. Open the chassis to access the drive area and remove any existing drive cages or blanking panels as needed.
• Align the backplane: Position the 4-bay backplane kit within the drive bay area, aligning mounting holes with the chassis. Ensure that the backplane’s connectors line up with the server’s internal SAS/SATA interconnects and backplane midplane (as applicable).
• Connect data and power cables: Attach the internal SAS/SATA data cables and power connections from the server to the backplane. Confirm that each drive position is securely connected and that cables are routed to avoid obstruction to fans and airflow.
• Secure and install drives: If you are adding drives, install 3.5" drive carriers into the backplane slots. Ensure each drive is seated firmly and that any locking mechanisms engage properly for hot-swap readiness.
• Close and power up: Reinstall the chassis cover, reconnect cables, and power on the server. Enter BIOS/UEFI or the RAID controller setup to verify drive detection and configure any desired RAID volumes or storage pools.
• Verify operation: Once the OS loads, check that all four drives are recognized by the RAID controller and operating system. Run a quick health check and monitor temperatures to ensure proper cooling and stability after installation.
