Upgrading the Trusted Platform Module
Prerequisites
1. Follow the safety guidelines listed in Safety instructions.
2. Follow the procedures in Before working inside your system.
NOTE: The NX440 system does not support UEFI mode.
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. Work with the customer to create and safely store
this recovery key. When replacing 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: 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, the removed TPM
cannot be reinstalled or installed on another system board.
NOTE:
● Ensure that your operating system supports the version of the TPM module being installed.
● Ensure that you download and install the latest BIOS firmware on your system.
● Ensure that the BIOS is configured to enable UEFI boot mode.

2. Press to hold the module down and remove the screw using the security Torx 8-bit shipped with the TPM module.
3. Slide the TPM module out from its connector.
4. Push the plastic rivet away from the TPM connector and rotate it 90° counterclockwise to release it from the system board.
