Built to support PCIe Gen5 speeds, it enables your server to take advantage of the latest accelerator cards and high‑bandwidth peripherals, helping you push compute capacity without compromising space or manageability.

• Dual PCIe Gen5 x16 slots (Full-height/Full-length): The riser kit provides two PCI Express 5.0 x16 connectors in a full‑height, full‑length footprint. This design maximizes compatibility with high‑performance graphics cards, accelerator cards, NVMe storage, and high‑bandwidth network adapters, delivering the dense, scalable expansion DL145 Gen11 servers demand for data‑center workloads. With PCIe Gen5, you gain substantial forward‑looking bandwidth to support data‑intensive applications, enabling faster data movement and lower bottlenecks across complex configurations.
• FHFL form factor for flexible deployment: Specifically engineered for full‑height, full‑length slot configurations, this riser kit fits naturally into server chassis that accommodate large cards and aggressive PCIe layouts. The FHFL design ensures secure seating, optimal airflow, and reliable electrical contact, which translates into stable long‑term performance in dense data‑center environments. This makes it an excellent choice for HPC nodes, AI inference servers, and enterprise deployments where space planning and airflow management are critical.
• Gen5 performance optimized for modern accelerators: By supporting PCIe Gen5 up to x16 per slot, this riser kit unlocks the full potential of next‑generation GPUs, FPGAs, and other accelerator devices. PCIe Gen5 delivers higher per‑lane bandwidth and improved signaling, enabling smoother data transfer, faster boot and initialization times for new cards, and improved sustained throughput under heavy workloads. It’s a forward‑looking upgrade path that extends the life of your DL145 Gen11 system while meeting today’s performance demands.
• Robust compatibility with HPE ecosystem: As an official component designed for HPE ProLiant platforms, the DL145 Gen11 x16 FHFL PCIe Gen5 Slot 2 Riser Kit integrates into the HPE server lifecycle with confidence. Expect verified electrical and mechanical compatibility, validated installation procedures, and streamlined service when paired with supported HPE BIOS, firmware, and management tools. This integration helps maintain warranty integrity and reduces the risk of misalignment or interoperability issues that can arise with generic third‑party risers.
• Future‑proof expansion with ease of installation: The kit is engineered to simplify expansion planning, enabling straightforward upgrades as your workloads evolve. With two Gen5 x16 paths, you can add memory‑intensive GPUs, high‑throughput NVMe adapters, or sophisticated networking accelerators without redesigning the server chassis. The user experience is enhanced by reliable connector alignment, sturdy mechanical mounting, and a design that minimizes downtime during installation, so you can scale performance with minimal operational disruption.

how to install HPE ProLiant DL145 Gen11 x16 FHFL PCIe Gen5 Slot 2 Riser Kit

• Power down the DL145 Gen11 server and unplug all power and network connections to ensure a safe, static‑free environment.
• Remove the server cover or access panel according to the HPE DL145 Gen11 service guide to expose the PCIe backplane area and the slot 2 region where the riser will be installed.
• Identify the dedicated slot 2 riser socket on the system board or backplane, following the manufacturer’s labeling and alignment markers to ensure proper insertion orientation.
• Carefully align the DL145 Gen11 x16 FHFL PCIe Gen5 Slot 2 Riser Kit with the socket, ensuring the connectors line up precisely. Press firmly but evenly to seat the riser without bending any pins or forcing seating alignment.
• Secure the riser kit with the appropriate mounting hardware provided with the kit, ensuring the assembly is snug but not over‑tight to prevent chassis strain or misalignment.
• Reconnect any removed cables or connectors, re‑attach the server cover, reconnect power, and boot the system. Enter the BIOS/UEFI to verify that both PCIe Gen5 x16 slots are detected and enabled, and install or update any necessary firmware or BIOS settings to optimize Gen5 operation.
