Install a riser 1/2 assembly

Use this information to install a riser 1 assembly or riser 2 assembly.

About this task

  • Read Installation Guidelines to ensure that you work safely.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.


  1. Touch the static-protective package that contains the new riser card to any unpainted surface on the outside of the server. Then, take the new riser card out of the package and place it on a static-protective surface.
  2. Install a riser card in a riser cage.

    1. Align the holes in the riser card with the mounting studs on the bracket. Install the riser card to the bracket in the direction as shown.
    2. Install the two screws to secure the riser card to the bracket.
  3. Install PCIe adapters. For information about supported PCIe adapters and PCIe slots, see PCIe slots and configurations.
    Carefully handle the PCIe adapter by its edges.

    1. Align the PCIe adapter with the PCIe slot on the riser card. Carefully press the PCIe adapter straight into the slot until it is securely seated and its bracket also is secured.
    2. Rotate the PCIe adapter retention latch to the closed position.
  4. Check the rearwall matrix and decide which rearwall brackets need to be installed or removed for installing your riser assemblies. See Install the rearwall brackets, Install the rearwall brackets and Install a B1/B2 rearwall bracket (middle).
  5. Install a riser 1 assembly or riser 2 assembly. The illustration shows installing the riser 1 assemblies. The procedure is the same for installing riser 2 assemblies.

    1. Align the riser adapter in the riser cage with the riser slot on the system board. Carefully press the riser card straight into the slot until it is securely seated.
    2. (Optional) If there is one screw on the riser cage, tighten the screw.

After you finish

Refer to Internal cable routing to connect any cables to the PCIe adapters.
