how to install Lenovo ThinkSystem 2U x8/x8 PCIe Riser3 Kit

Before you begin, power down the server, unplug all power sources, and discharge any static electricity by touching a grounded metal surface. Prepare a clean, static-free work area and organize all components to prevent misplacement during installation. Verify you have the correct ThinkSystem 2U chassis and that the system firmware, BIOS, and drivers are up to date before proceeding.

Access the server chassis and locate the PCIe expansion slot region where the Riser3 kit will be installed. If your server uses a removable top cover or side access panel, remove it according to Lenovo maintenance guidelines, taking care to avoid damage to any delicate connectors or cables. Identify the riser slot pair that corresponds to the Riser3 kit’s edge connectors, confirming alignment with the motherboard backplane interfaces. Align the riser’s connector edge with the server’s PCIe backplane slots; ensure that pins are upright and decals or orientation marks on the riser align with the chassis guides.

Gently insert the Riser3 kit straight into the PCIe slot until it is seated firmly. Do not apply side pressure or force, as misalignment can damage the backplane or connectors. Once seated, secure the riser with the provided mounting hardware, using only the screws or brackets specified by Lenovo for this kit. Hand-tighten to avoid over-torquing and ensure a stable, vibration-resistant installation. After securing the riser, verify that any attached PCIe add-in cards, cables, or riser-to-backplane connectors are not kinked, bent, or under tension, and that airflow pathways remain clear for optimal cooling.

Route any PCIe device power or data cables carefully, keeping them away from fans, heatsinks, and airflow channels. If the kit requires additional cables or adapters, connect them per the Lenovo documentation, ensuring all connectors are fully seated. Reinstall the server cover, reattach any internal panels, and reconnect power. Boot the server and enter the BIOS/UEFI or system management console. Confirm that the new PCIe slots are detected and enabled; adjust slot configurations and lane allocations as necessary to optimize performance for your intended PCIe devices. Finally, install or update the operating system drivers and management software to recognize the newly added PCIe devices and to monitor their activity, temperature, and performance metrics in real time.

Power on the system and perform a basic post-check to ensure the Riser3 kit is operating correctly. Run a diagnostic suite or a trusted virtualization or benchmarking test to verify stable throughput across the new PCIe lanes and confirm there are no slot conflicts with other expansion cards. Maintain a record of your hardware changes for future service events and ensure your monitoring tools are configured to alert on any PCIe or device-level anomalies. If you encounter any issues during installation, consult Lenovo support resources or your authorized service provider for guidance to avoid voiding warranties or compromising system stability.
