how to install Lenovo ThinkSystem SR550/SR590/SR650 x16/x8 PCIe FH Riser 1 Kit

• Prepare the server: Power down the system, unplug power cords, and discharge any static electricity. Remove the server cover and gain access to the PCIe riser area according to Lenovo service documentation for the SR550, SR590, or SR650 model you are servicing.
• Identify the correct riser slot: Locate the PCIe riser bay designated for the x16/x8 configuration in your ThinkSystem chassis. Verify that the slot matches the FH riser connector and that no other adapters obstruct the installation path.
• Install the riser: Align the riser connectors with the motherboard edge and seat it firmly into the PCIe slot. Use the included mounting hardware to secure the riser to the chassis or riser cage as specified by Lenovo’s installation guidelines.
• Route and secure cables: If your configuration includes PCIe devices that require external cabling (for example, certain storage or network adapters), route cables neatly to avoid interference with fan assemblies and ensure adequate airflow. Use cable ties or guides to maintain clean airflow paths.
• Install PCIe devices: Insert the PCIe adapters into the appropriate x16 or x8 lanes supported by the riser configuration. Confirm that each card is fully seated and secured in its slot with screws if required by the chassis design.
• Reconnect power and verify: Reinstall the server cover, reconnect power, and boot the system. Enter the BIOS/UEFI to confirm that the PCIe devices are recognized and that the lane configuration reflects the x16/x8 setup. Update firmware or BIOS as recommended by Lenovo if compatibility issues are observed.
• Test and confirm performance: After the operating system loads, verify that the installed PCIe devices are functioning correctly. Run basic I/O tests or vendor-provided validation tools to confirm lane performance and device stability under typical workloads.
