How to install HPE ProLiant Server Family Riser Cards

Installing a ProLiant riser card is a straightforward process that follows standard server maintenance procedures. To ensure a safe and successful installation, prepare your workspace, review your server’s maintenance manual for model-specific steps, and follow these general guidelines. Always power down, unplug, and discharge any static electricity before handling internal components. Ground yourself using an anti-static strap if available, and keep track of screws and connectors to avoid misplacements during reassembly.

• Step 1 — Power down and prepare: Power down the server, remove the access panel, and disconnect power cables. Place the unit on a stable, non-conductive surface and ensure you have adequate lighting to view internal components.
• Step 2 — Access the riser slot: Identify the correct PCIe riser expansion slot for your ProLiant model. Some chassis provide dedicated riser slots beneath the motherboard tray or behind a removable shroud. Carefully remove any protective covers, if present, and verify there is no obstruction in the slot.
• Step 3 — Remove existing riser or prepare the new card: If replacing an older riser, unscrew and detach it following the server’s maintenance procedure. If installing a new riser, prepare the card by verifying connectors and ensuring it is free of debris. Handle the card by its edges to avoid damaging components.
• Step 4 — Install the riser card: Align the riser card with the slot’s connector, then press firmly to seat the card evenly. Secure the card with the appropriate screws or retention mechanism as defined by your server model. Double-check that the card is fully seated and that there is no visible gap between the slot and the riser.
• Step 5 — reconnect, close, and test: Reattach any cables or shielding that were removed for access, replace the server cover, and reconnect power. Power up the server and enter the system BIOS/UEFI or iLO interface to confirm that the riser card is detected. Run a basic POST check and verify that the new PCIe devices are recognized by the operating system once booted.

For model-specific steps, refer to your server’s maintenance and installation guide. While the general process remains consistent across ProLiant families, connector orientations, screw locations, and required firmware versions can vary. After installation, ensure firmware and drivers are up to date to realize the full benefits of the expanded PCIe capabilities and to maintain compatibility with future hardware and software updates.

Frequently asked questions

• Q: What is the purpose of a riser card in HPE ProLiant servers?
• A: A riser card provides additional PCIe expansion options by connecting to the motherboard’s PCIe lanes, enabling more devices to be used inside the server while maintaining a compact form factor.
• Q: Are HPE ProLiant riser cards compatible with all ProLiant models?
• A: Riser card compatibility depends on the server model and firmware version. Always verify compatibility with your specific ProLiant model and consult the vendor’s compatibility matrix before purchase or installation.
• Q: Do I need special drivers to use the new PCIe devices on a riser card?
