WARNING! Ensure that the system is powered off and all power sources have been
disconnected from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
IMPORTANT: You must run the supported version of the HP-UX operating system to utilize
the TPM security component.
