Card Riser PCIe x16 Lenovo 5C51D95675 pentru extindere server

Lenovo 5C51D95675 is a PCIe x16 riser card engineered to provide an additional PCIe x16 expansion slot on compatible Lenovo server platforms. It allows installation of full-length PCIe cards by repositioning the slot away from the motherboard plane to accommodate chassis constraints and improve access. The riser supports installation of graphics accelerators, network interface cards, RAID or HBAs and other PCIe x16 devices to increase processing, networking and storage I/O capabilities.

Advantages

The riser card is designed for straightforward mechanical integration in Lenovo server chassis that accept this form factor, offering a reliable electrical interface to the system PCIe bus. It preserves signal integrity for x16 lanes while enabling physical placement of expansion cards where the motherboard layout or drive bays would otherwise block direct installation. The component reduces the need for custom adapters and minimizes internal cable routing by providing a dedicated, board-mounted expansion solution.

Suitable for

• Installing full-length PCIe x16 graphics or accelerator cards in constrained chassis
• Adding high-performance network adapters (10GbE, 25GbE, or similar) when onboard slots are limited
• Expanding storage controller or HBA capacity for additional drives or RAID configurations
• Upgrading server I/O capability without changing the motherboard

Key specifications

• Interface: PCI Express x16 electrical interface
• Form factor: Riser card designed for compatible Lenovo server chassis
• Supported card length: Full-length PCIe add-in cards (depends on chassis clearance)
• Lanes: x16 signal mapping for maximum bandwidth according to platform support
• Compatibility: Designed for specific Lenovo server models that accept this riser form factor

How to use

Turn off and disconnect power from the server before opening the chassis. Locate the riser socket or mounting position indicated by the server maintenance guide and carefully seat the riser card into the designated connector on the system board or chassis backplane. Secure the riser to the chassis using the provided standoffs or screws to ensure stable mechanical support. Insert the PCIe x16 add-in card into the riser slot, verify proper seating and retention, then close the chassis and restore power. After booting, confirm that the server firmware and operating system detect the installed card and install any required drivers or firmware updates.

Recommendations

Verify chassis compatibility and available clearance for full-length cards prior to purchase. Check the server hardware compatibility list or maintenance manual to ensure platform support for the riser and the intended PCIe device. Use appropriate anti-static precautions when handling the riser and add-in cards, and update system firmware if necessary to enable full functionality of installed PCIe devices.
