HP Trusted Platform Module option
Use these instructions to install and enable a TPM on a supported server. This procedure includes three
sections:
1. Installing the Trusted Platform Module board (on page 20).
2. Retaining the recovery key/password (on page 21).
3. Enabling the Trusted Platform Module (on page 21).
TPM installation requires the use of drive encryption technology, such as the Microsoft® Windows®
BitLocker™ Drive Encryption feature. For more information on BitLocker™, see the Microsoft website
(http://www.microsoft.com
).
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 becomes a permanent part of the system
board.
• When installing or replacing hardware, HP service providers cannot enable the TPM or the
encryption technology. For security reasons, only the customer can enable these features.
