Remove the PCIe riser assembly

Follow instructions in this section to remove the PCIe riser assembly.

About this task

To avoid potential danger, make sure to read and follow the safety information.

Attention

Read Installation Guidelines and Safety inspection checklist to make sure that you work safely.

Note

Depending on the specific configuration, the hardware might look slightly different from the illustrations in this section.

Procedure

  1. Make preparations for this task.
    1. Power off the node (see Power off the node); then, disconnect all external cables from the node.
      Note
      If necessary, press the release clip with a flat-head screwdriver to remove an external network cable from the rear of a 2U node.

    2. Remove the node from the chassis (see Remove a node from the chassis); then, carefully lay the node on a flat, static-protective surface, orienting the node with the front toward you.
      Note
      • When removing the node, note the node tray number and make sure to install the node in the same tray from which it was removed. Reinstalling the node into a different tray requires the node to be reconfigured.
      • For safety, make sure to hold the node with both hands when lifting the node.
    3. Remove the top cover (see Remove the top cover).
    4. If the GPU air duct is installed in the node, remove it (see Remove the GPU air duct).
    5. If the internal adapter bracket is installed and blocks the way of removing the fan cage, disconnect all the cables from the internal adapter; then, remove the internal adapter bracket from the node (see Remove the internal adapter bracket).
    6. Disconnect all the fan cables from the system board; then, remove the fan cage from the node (see Remove the fan cage).
  2. Remove the PCIe riser assembly from the node.
    1. Loosen the captive screw that secures the PCIe riser assembly to the node.
    2. Disconnect the PCIe riser power cable from the riser.
    3. Carefully hold the PCIe riser assembly by its edges and lift it out of the node.

  3. If necessary, disconnect all the PCIe riser cables from the system board (see PCIe riser cable routing); then, lay the PCIe riser assembly on a flat, static-protective surface.
    Note

After you finish

  1. To replace a PCIe adapter, see Remove a PCIe adapter and Install a PCIe adapter.
  2. If necessary, replace or remove the PCIe riser card from the riser cage.

  3. Install a replacement unit or filler (see Install a PCIe riser assembly).
    Note
    For proper cooling and air flow, make sure to install a riser filler when there is no riser cage installed in the node.
  4. If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
