How to install HPE ProLiant DL380 Gen11 2U x16/x16/x16 Primary Riser Kit

• Power down and prepare the server: Shut down the DL380 Gen11, unplug power cords, and surface‑clean the work area to prevent static discharge. Ensure you’re working on a grounded anti‑static mat or strap.
• Access the expansion plane: Remove the server cover, service door, and any front bezel components as required by your DL380 Gen11 maintenance procedure to access the riser plane.
• Remove existing riser components (if applicable): If replacing or upgrading an existing riser configuration, carefully disconnect and remove the prior riser module following the factory service guide.
• Align and seat the Primary Riser Kit: Gently insert the riser into the designated expansion plane connectors, ensuring proper alignment with the motherboard PCIe slots and mounting points. Do not force connectors; they should seat with a light, even push.
• Secure the riser kit: Fasten the riser kit to the chassis using the supplied screws or retention hardware. Confirm that all connectors are fully engaged and that the module sits flush against the mounting brackets.
• Reconnect, reassemble, and test: Reinstall any removed covers, reattach power, and power on the server. Enter the system firmware or operating system to verify detection of all three PCIe x16 expansion lanes, and run a baseline I/O benchmark to confirm stability and throughput.
