User Manual

IMPORTANT:
In UEFI Boot Mode, the HPE TPM 2.0 Gen10 Kit can be configured to operate as TPM 2.0 (default) or
TPM 1.2 on a supported server. In Legacy Boot Mode, the configuration can be changed between TPM
1.2 and TPM 2.0, but only TPM 1.2 operation is supported.
HPE Trusted Platform Module 2.0 Guidelines
CAUTION:
Always observe the guidelines in this document. Failure to follow these guidelines can cause hardware
damage or halt data access.
When installing or replacing a TPM, observe the following guidelines:
• Do not remove an installed TPM. Once installed, the TPM is bound to the system board. If an OS is
configured to use the TPM and it is removed, the OS may go into recovery mode, data loss can occur, or
both.
• When installing or replacing hardware, Hewlett Packard Enterprise service providers cannot enable the
TPM or the encryption technology. For security reasons, only the customer can enable these features.
• When returning a system board for service replacement, do not remove the TPM from the system board.
When requested, Hewlett Packard Enterprise Service provides a TPM with the spare system board.
• Any attempt to remove the cover of an installed TPM from the system board can damage the TPM cover,
the TPM, and the system board.
• If the TPM is removed from the original server and powered up on a different server, data stored in the
TPM including keys will be erased.
• When using BitLocker, always retain the recovery key/password. The recovery key/password is required to
complete Recovery Mode after BitLocker detects a possible compromise of system integrity or system
configuration.
• Hewlett Packard Enterprise is not liable for blocked data access caused by improper TPM use. For
operating instructions, see the TPM documentation or the encryption technology feature documentation
provided by the operating system.
Disabling Chipset-TPM
CAUTION:
Chipset-TPM is not available after power is removed from the system and the HPE TPM 2.0 Gen10 Kit
is installed. Do not install the HPE TPM 2.0 Gen10 Kit if Chipset-TPM is enabled and the operating
system is using Chipset-TPM features. Otherwise, the OS may go into recovery mode, data loss can
occur, or both. If an OS is installed and using Chipset-TPM, follow the OS vendor instructions to disable
the OS TPM features before changing any TPM functionality.
Before installing and enabling the HPE TPM 2.0 Gen10 Kit, verify that Chipset-TPM is disabled. For more
information on disabling Chipset-TPM, see the UEFI System Utilities User Guide for HPE ProLiant Gen10
Servers and HPE Synergy on the Hewlett Packard Enterprise website.
