how to install Lenovo 4C57A15016

• Power down the server, unplug the power cords, and follow all safety procedures outlined in your service manual.
• Remove the existing drive cage or backplane if required, keeping track of any screws or sliders for reuse.
• Align the 4C57A15016 backplane with the server chassis rack rails or mounting brackets and slide it into the 2U bay, ensuring the connectors align with the system’s backplane interface slot.
• Secure the backplane to the chassis using the supplied screws or mounting hardware, then attach the NVMe drive sleds into the 8 bays if they are not pre-installed in the backplane.
• Connect the backplane data interface to the server’s NVMe controller or midplane connectors as specified by Lenovo documentation, verify proper seating of all cables, and reseat drive sleds as needed.
• Reinstall the chassis cover, reconnect power, and power on the server. Enter the system setup or BIOS/UEFI to confirm the backplane and all NVMe drives are detected, then initialize and configure the drives through your preferred storage controller or operating system.
