Removing the TPM

Removing the TPM

  • If the private key of the TPM interface board is used to encrypt data, back up the data before removing the TPM.

    If the data is not backed up, the encrypted data cannot be decrypted after the TPM is replaced.

  • If the TPM function has been set on the BIOS, record the settings before removing the TPM. After replacing the TPM, configure the related settings on the BIOS again.

    For details, see the Huawei Server Purley Platform BIOS Parameter Reference.
