Lenovo ThinkSystem SR550/SR590/SR650 (x16/x8)/(x16/x16) PCIe FH Riser 2 Kit

The Lenovo PCIe FH Riser 2 Kit for ThinkSystem SR550, SR590 and SR650 is a full-height riser solution that enables flexible PCIe expansion in compatible Lenovo server platforms. Designed to provide reliable internal connectivity, this riser supports mixed lane configurations to accommodate a variety of add-in cards and high-performance peripherals. The multicolour design identifies connectors and card positions for easier installation and maintenance.

Advantages

This riser kit supports both x16/x8 and x16/x16 PCIe configurations, offering flexibility when populating PCIe slots. Its internal form factor is optimized for rack server environments, providing stable electrical connections and maintaining signal integrity under typical data center conditions. The design simplifies system upgrades and expansions while remaining compatible with specified ThinkSystem models.

Suitable for

• Adding multiple PCIe cards such as network adapters, storage controllers or accelerators
• Server upgrades where additional full-height PCIe slots are required
• Data center environments running compute, storage or networking workloads

Key specifications

• Host interface: PCIe
• Output interface: PCIe
• PCIe lane configurations: x16/x8 and x16/x16 supported
• Form factor: internal, full-height riser
• Colour: multicolour (connector/cable identification)

How to use

Install the riser kit into a compatible Lenovo ThinkSystem SR550, SR590 or SR650 server following the server manufacturer's service manual. Power down the server and disconnect power before installation. Align the riser with the server's riser slot and secure it per the chassis instructions. After seating the riser, install PCIe cards into the available full-height slots and verify seating and retention brackets. Reconnect power and confirm that the system firmware recognizes installed devices and lane configurations.

Recommendations

Do not use this older Riser 2 kit with systems that require compatibility with the A100; that combination is not supported. For reliable operation, ensure firmware and BIOS are up to date and use the riser only in the specified Lenovo ThinkSystem models. Follow electrostatic discharge (ESD) precautions and data center installation procedures.
