Step 1. Remove the riser assembly by grasping its edges and carefully lift it straight up and off the chassis.
Then, lay it upside down on a flat, clean, and static-protective surface.
Step 2. Locate an appropriate PCIe slot. See "Rear view" on page 22 to identify the PCIe slots of your
server.
Step 3. If the slot is covered with a slot bracket, open the retention latch and remove the slot bracket from
the riser assembly. Store the bracket in case that you later remove the PCIe adapter and need the
bracket to cover the place.
Step 4. Position the PCIe adapter near the PCIe slot. Then, carefully press the PCIe adapter straight into
the slot until it is securely seated. Ensure that the PCIe adapter bracket is secured by the riser
adapter bracket.
