how to install Supermicro RSC-R2UU-A4E8

• Power down the server and unplug all power sources. Ground yourself to prevent electrostatic discharge and remove the chassis cover to access the motherboard area.
• Identify a compatible PCIe slot on the motherboard and an available expansion plane area in the chassis that aligns with the left-slot riser card’s orientation. Confirm there is sufficient clearance for all four installed PCIe cards once the riser is seated.
• Carefully align the left-slot riser card with the motherboard PCIe edge connector and the corresponding expansion plane or riser slot. Apply even pressure to seat the card securely, ensuring a firm, worry-free connection without bending the connector pins.
• Secure the riser card to the chassis using the appropriate screws or retention hardware per the chassis design. Ensure the card remains stable under typical operating conditions to reduce vibration-related wear and to maintain PCIe signal integrity.
• Route any needed cables or interface connections cleanly to avoid obstruction of airflow and to prevent cable interference with fans or other components. Reattach the chassis cover and power up the server. Enter the BIOS/UEFI to confirm that all four PCIe x8 slots are recognized and that the expansion cards are enumerated correctly by the system.
