Removing and replacing the system board
IMPORTANT: If your system board has a TPM installed, you must order a new TPM when you
order a replacement system board.
Before replacing the system board, you must first back up the current TPM settings. See the HP-UX
operating system documentation for more information.
The TPM is not a customer-installable component. If the TPM needs to be replaced, contact an HP
authorized service provider.
CAUTION: Once the TPM is installed on your system board, it cannot be removed. If the TPM
fails, the system board needs to be replaced. Attempting to remove the TPM from the system board
will void any existing HP service contract and cause the server to fail.
