How to install Lenovo ThinkSystem SR250 x16 PCIe Riser

Step 1: Power down the server, shut it down cleanly through the operating system, and disconnect all power and network cables to prevent any electrical hazards during installation.

Step 2: Remove the server cover or access panel according to Lenovo’s service documentation to expose the motherboard/backplane area where the PCIe riser connects.

Step 3: Locate the dedicated PCIe riser slot on the SR250 motherboard/backplane layout. Confirm there is an available slot and no adjacent components that would obstruct the riser’s orientation.

Step 4: Align the SR250 x16 PCIe Riser with the riser connector and seating guide. Gently but firmly insert the riser into the slot until it is fully seated, ensuring the connectors are fully mated and flush with the backplane.

Step 5: Secure the riser to the chassis mounting points using the supplied screws or fasteners. Tighten to specification to prevent movement during vibration or handling inside the rack.

Step 6: If you plan to install PCIe expansion cards, insert each card into the riser’s x16 slot, one at a time, and secure with its own retention mechanism. Verify that the cards are seated evenly and aligned with the PCIe slots.

Step 7: Reassemble the server cover, reconnect power and cables, and power on the system. Enter the BIOS/UEFI to confirm the PCIe riser and any installed cards are detected, then load the operating system and drivers as needed.

Note: Always handle components with anti‑static precautions and consult Lenovo’s official installation guide for model‑specific instructions or variations in chassis configuration. This ensures optimal performance and maintains warranty coverage where applicable.
