To remove the system board, complete the following steps.
  1. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
    Attention
    Do not allow the server to fall over.
  2. Unlock and remove the left-side cover (see Removing the left-side cover).
  3. Remove the air baffle (see Removing the air baffle).
  4. Remove the fan cage assembly (see Removing the fan cage assembly).
  5. Note where the cables are connected to the system board; then, disconnect them.
