1. Make preparations for this task.
   1. Power off the node (see Power off the node); then, disconnect all external cables from the node.

   3. Remove the top cover (see Remove the top cover).
   4. If the PCIe riser assembly is installed, remove it from the node and disconnect the PCIe cables from the system board (see Remove the PCIe riser assembly and Internal cable routing).
2. Disconnect the cables from the rear I/O module.
3. Remove the rear I/O module.
   1. Remove the four screws from the rear I/O module as illustrated.
