how to install Lenovo ThinkSystem 1U G3 X16/x16 PCIe Riser1 LP+LP Option Kit

• Power down the server, unplug from any power source, and follow your data center’s safety and lockout procedures before opening the chassis.
• Open the ThinkSystem 1U chassis and locate the PCIe riser area designated for expansion cards. Remove any existing riser components if the upgrade replaces or supplements them, following the server maintenance guide.
• Carefully align the Riser1 LP+LP kit with the motherboard riser connectors and seating points. Insert the riser into the slot with even pressure, ensuring a secure, square seating and that all connectors are fully mated.
• Secure the riser to the chassis using the appropriate mounting screws and verify that there is sufficient clearance around the installed PCIe slots to maintain unobstructed airflow for both the riser and any PCIe cards you plan to attach.
• Insert your PCIe devices (such as GPUs or NICs) into the dual x16 expansion slots, ensuring that each card is firmly seated and that any required power connectors from the chassis are connected to the devices as per the device documentation.
• Reconnect any data and power cables, close the chassis, and power the server back on. Enter the BIOS/UEFI and confirm that the PCIe devices are recognized. Update firmware if necessary using Lenovo management tools, and verify the operating system detects the new expansion hardware.
