How to install Lenovo ThinkSystem 2U E/x16/x16 PCIe G4 Riser 1/2 Option Kit

• Step 1: Power down the server and disconnect all power sources. Remove the server cover to access the interior, following your data center’s safety procedures and Lenovo’s maintenance guidelines to prevent ESD and component damage.
• Step 2: Identify the designated PCIe riser slots within the 2U chassis. Review the ThinkSystem service and maintenance manual to confirm slot alignment, mounting points, and connector orientation specific to your model.
• Step 3: If existing risers or expansion cards are present, carefully detach them from the motherboard or backplane, noting any attached cables and securing screws. Keep track of screws and spacers, as you will reuse some hardware during installation.
• Step 4: Align the Lenovo ThinkSystem 2U E/x16/x16 PCIe G4 Riser 1/2 Option Kit riser cards with the slot openings and connector pins. Gently seat the risers, ensuring a clean, snug engagement without forcing the connectors. Secure the risers with the provided mounting hardware to maintain rigid alignment during operation and vibration conditions.
• Step 5: Route any required power or signal cables in a manner that preserves airflow and prevents cable pinch. Use cable ties or guides to keep cables organized and away from fan blades. Confirm that cables are not contacting moving components or obstructing PCIe slots.
• Step 6: Reinstall the server cover, reconnect all power sources, and power up the system. Enter the BIOS/UEFI to verify that the new riser configuration is recognized and that the PCIe devices are detected with the expected lane assignments.
• Step 7: In the host operating system, install or update drivers for the PCIe devices connected through the riser. Run a basic diagnostic to confirm device visibility, bandwidth, and stability under representative workloads. If you plan to use multiple PCIe devices, verify that inter-device bandwidth and resource allocation meet your performance goals.
• Step 8: Conduct a light operational test to monitor temperatures, fan speeds, and power consumption during initial boot and initial load. Ensure that the system remains within safe thermal margins and that cooling is adequate for the added components.
