Removing system board

Prerequisites

CAUTION If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create a recovery key during program or system setup. Be sure to create and safely store this recovery key. If you replace this system board, you must supply the recovery key when you restart your system or program before you can access the encrypted data on your drives.
CAUTION Do not attempt to remove the TPM plug-in module from the system board. After the TPM plug-in module is installed, it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in module breaks the cryptographic binding, and it cannot be reinstalled or installed on another system board.
  1. Follow the safety guidelines listed in Safety instructions.
  2. Follow the procedure listed in Before working inside your system.
  3. Remove the following:
    1. Non-GPU air shroud or GPU air shroud
    2. Cooling fan assembly.
    3. Processor and heat sink module
    4. Backplane cables connected to the system board
    5. Power interposer board (PIB).
      CAUTION When replacing the system board, disconnect the cables from the system board, but do not disconnect the cables attached to the PIB.
    6. Expansion card risers
    7. iDSDM/vFlash card
    8. Internal USB key, if installed
    9. USB 3.0 module cable connected to the system board
    10. Processor blanks, if installed
      CAUTION To prevent damage to the processor socket when replacing a faulty system board, ensure that you cover the processor socket with the processor dust cover.
    11. Network daughter card.
    12. Drive cage (rear), if installed.
