About this task

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:Once 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.

Removing the TPM

Steps
  1. Locate the TPM connector on the system board.
  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.
  5. Pull the plastic rivet out of its slot on the system board.

Installing the TPM

Steps
  1. To install the TPM, align the edge connectors on the TPM with the slot on the TPM connector.
  2. Insert the TPM into the TPM connector such that the plastic rivet aligns with the slot on the system board.
  3. Press the plastic rivet until the rivet snaps into place.
