How to install Lenovo ThinkSystem SR250/SR150 x8/x8 PCIe Riser

• Power down the server, unplug power cords, and discharge static from yourself before handling any internal components.
• Remove the server chassis cover to gain access to the motherboard area and the dedicated PCIe riser slot or mezzanine connector specified by Lenovo for the SR250/SR150 platform.
• Identify the correct riser connector on the motherboard area and prepare the riser card for installation, ensuring the connector matches the alignment of the slot.
• Gently insert the riser into the motherboard riser slot, making sure the connectors seat evenly. Align the screw holes on the riser with the chassis mounting points.
• Secure the riser with the appropriate screws, then route or manage any necessary cables or backplane connections as required by the server model and your PCIe device mix.
• Install any PCIe devices (NICs, storage controllers, RAID adapters, or accelerators) into the two x8 slots on the riser, following device manufacturer instructions for seating and mounting.
• Replace the server cover, reconnect power, and power on the system. Enter the system BIOS/UEFI to verify the riser is detected and that PCIe devices are recognized by the operating system.
