Replacing the TPM
Use the following procedure to install the TPM.
IMPORTANT: The TPM is only supported on the HP-UX operating system. You must be running
the supported version of the HP-UX OS to use the TPM security component.
The TPM replacement must be performed by an authorized HP CE, but you can move the TPM
from a failed system board to a new system board.
1. Install the new TPM on the system board by pushing it down onto the posts on the system
board.
For the location of the TPM on the system board, see Figure 63 (page 137). The TPM is keyed
to fit only one way.
2. Install the access panel.
See “Replacing the Right Access Panel” (page 117).
3. Place the server blade back into the enclosure and power it up.
See “Replacing the Server Blade in the Enclosure” (page 115).
4. Synchronize the TPM state with the system board by doing the following:
Examine the current TPM state at EFI by using the secconfig command.
• If the TPM is enabled, disable it with the secconfig tpm off command.
• If the TPM is disabled, enable it with the secconfig tpm on command.
