How to install Lenovo ThinkSystem SR550/SR590/SR650 PCIe FH Riser 2 Kit

• Step 1: Power down the server completely, unplug the power cords, and ground yourself to prevent static discharge before handling internal components.
• Step 2: Remove the server cover and locate the PCIe expansion area that corresponds to the FH riser slot designated for the SR550/SR590/SR650 family. Review any server maintenance documentation to confirm the correct riser placement.
• Step 3: If a previous PCIe riser is installed, carefully release and remove it following the system maintenance guidelines. Inspect connectors for dust or debris and ensure the PCIe slot and mounting points are clean and unobstructed.
• Step 4: Align the Lenovo ThinkSystem PCIe FH Riser 2 Kit with the motherboard PCIe slot and the chassis’ mounting holes. Gently seat the riser into the slot, applying even pressure to avoid bending pins, then secure the kit with the provided screws or mounting hardware. Confirm that the connector is fully seated and that the riser sits flush with the chassis.
• Step 5: If you will be installing PCIe devices, connect any necessary power or data cables as required by your server configuration, then reassemble the chassis cover. Reconnect power, boot the server, and enter BIOS/UEFI to verify PCIe slot recognition and to adjust any lane or slot settings as recommended by Lenovo for your workload. Finally, install or update drivers and firmware to ensure optimal compatibility and performance.
