Step 1. Start the server and when prompted, press F1 to display Lenovo XClarity Provisioning Manager.
Step 2. If the power-on Administrator password is required, enter the password.
Step 3. From the System Summary page, click
Update VPD

Step 4. Set the policy to one of the following settings.
•
TCM enabled - China only
. Customers in the People’s Republic of China should choose this
setting if a TCM adapter is installed
•
TPM enabled - ROW
. Customers outside of the People’s Republic of China should choose this
setting.
•
Permanently disabled
. Customers in the People’s Republic of China should use this setting if
no TCM adapter is installed
Although the setting
undefined
is available as a policy setting, it should not be used.
