How to Install Lenovo ThinkSystem SR645 Rear 2x2.5" NVMe Backplane Option Kit v2

Installing the Lenovo ThinkSystem SR645 Rear 2x2.5" NVMe Backplane Option Kit v2 is designed to be straightforward for IT professionals familiar with server maintenance. Follow these general steps to upgrade your SR645 with the rear NVMe backplane, while ensuring data safety and system integrity:

• Prepare the system: Power down the server, disconnect all external cables, and perform a proper chassis grounding procedure to prevent static discharge. Wait for components to reach ambient temperature before handling.
• Access the chassis: Remove the server cover or access panel according to the ThinkSystem SR645 service manual. Ensure you have clear space to work and that you can reach the rear expansion area where the backplane will be installed.
• Align and install the backplane: Position the rear 2x2.5" NVMe backplane in its designated bay or mounting slot within the chassis. Secure it with the provided hardware, ensuring the backplane is seated straight and firmly fastened to prevent any misalignment that could impact drive seating or airflow.
• Connect drives and cables: If you are replacing existing drives, carefully map the NVMe drive connections to the backplane and the server’s PCIe/NVMe interconnect points. Attach any required driver or interconnect cables as specified in the SR645 documentation, making sure there are no pinch points or strained cables that could affect airflow or cooling.
• Reassemble and test: Reinstall the server cover, reconnect power, and boot the system. Enter the server’s management interface to verify backplane recognition, drive detection, and any OEM storage policies. Run a basic drive health check and confirm that each NVMe drive is reporting correctly to the OS and storage controller.
