Install a PCIe riser assembly

Follow instructions in this section to install a PCIe riser assembly. The procedure must be executed by a trained technician.

About this task

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.
  • The server support up to three PCIe risers, see the following illustration for corresponding locations.

Procedure

  1. Install the PCIe riser assembly in riser slot 1.
    1. Connect the PCIe riser assembly cables. See PCIe riser cable routing for more information on the internal cable routing.
    2. Align the guide hole on the PCIe riser with the guide post on the system board assembly; then, insert the PCIe riser assembly into the PCIe slot on the system board assembly.
    3. Fasten the thumbscrew to secure the PCIe riser assembly.

  2. Install the rear riser support bracket before installing PCIe riser assembly in riser slot 2.
    1. Insert the rear riser support bracket into the riser slot until it is in place.
    2. Fasten the ten M3 screws (PH2, 10 x M3, 0.9 newton-meters, 8 inch-pounds) to secure the rear riser support bracket to the chassis.

  3. Install the PCIe riser assembly in riser slot 2.
    1. Connect the PCIe riser assembly cables. See PCIe riser cable routing for more information on the internal cable routing.
    2. Align the guide hole on the PCIe riser with the guide post on the system board assembly; then, insert the PCIe riser assembly into the PCIe slot on the system board assembly.
    3. Fasten the thumbscrew to secure the PCIe riser assembly.

  4. If necessary, attach the labels to both ends of the cable.
    1. Attach the white space portion of the label to one end of the cable.
    2. Wrap the label around the cable and attach it to the white space portion.
    3. Repeat to attach the other label to the opposite end of the cable.
