Enable TPM

The server supports Trusted Platform Module (TPM), Version 1.2 or Version 2.0

Note
For customers in Chinese Mainland, integrated TPM is not supported. However, customers in Chinese Mainland can install a Trusted Cryptographic Module (TCM) adapter or a TPM adapter (sometimes called a daughter card).
When a system board is replaced, you must make sure that the TPM policy is set correctly.
CAUTION
Take special care when setting the TPM policy. If it is not set correctly, the system board can become unusable.
  • Set the TPM policy
    By default, a replacement system board is shipped with the TPM policy set to undefined. You must modify this setting to match the setting that was in place for the system board that is being replaced.
  • Hide/observe TPM
    TPM is enabled by default to encrypt data transfer for system operation. Optionally, you can disable TPM using Unified Extensible Firmware Interface (UEFI) or Lenovo XClarity Essentials OneCLI.
  • Update the TPM firmware
    Optionally, you can update the TPM firmware using Lenovo XClarity Essentials OneCLI.
