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 hard drives.
CAUTION: Do not attempt to remove the TPM plug-in module from the system board. Once the TPM plug-in module is installed,
it is cryptographically bound to that specic 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.
