Remove the PCIe riser assembly

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.
   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).
2. Remove the PCIe riser assembly from the node.
   1. Loosen the captive screw that secures the PCIe riser assembly to the node.
   2. Carefully hold the PCIe riser assembly by its edges and lift it out of the node.
   3. Disconnect the PCIe riser power cable from the riser.

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.
