How to Install Lenovo ThinkSystem x16/x16 PCIe G4 Riser3 Kit

Follow these steps to install the Riser3 Kit safely and effectively. Ensure you have the proper tools, and consult your server’s maintenance manual for chassis-specific procedures and safety guidelines.

• Power down the server completely, unplug all power sources, and discharge static from your body before handling internal components. Move the system to a static-free workspace and wear an anti-static wrist strap if available.
• Remove the server cover or access panel according to Lenovo’s service documentation to access the motherboard, PCIe slots, and backplane region where the riser will be installed.
• Identify the designated PCIe Gen4 x16/x16 expansion slot pair and, if required by your chassis, temporarily remove adjacent blanking plates to accommodate the Riser3 Kit’s form factor.
• Align the Riser3 Kit carefully with the motherboard/backplane connectors and press evenly to seat it fully. Avoid applying lateral force; ensure the connectors engage securely and that the module sits flush with the chassis.
• Reconnect any necessary power or auxiliary connections specified for the riser module. Reinstall the server cover, ensuring all cabling is routed for optimal airflow and accessibility.
• Power on the system and enter the BIOS/UEFI to verify that the riser is detected. Install or update drivers for any GPUs, NVMe devices, or accelerators connected through the riser, then run a quick validation test to confirm proper operation.
