Removing and Replacing the Trusted Platform Module
The Trusted Platform Module (TPM) is an optional security component which enhances security
capabilities for the server if it is running the HP-UX operating system. The TPM is a security
chip that is unique to the server. It performs key security processes independent of other hardware
components. The TPM creates and stores additional encryption keys from the root key of the
system. The encryption keys created by the TPM encapsulate system application encryption keys
to provide an additional layer of security for sensitive system data.
The fundamental capabilities of the TPM include:
•
Platform authentication
•
Sensitive information protection
•
Data integrity
•
System privacy
IMPORTANT:
You must run the supported version of the HP-UX operating system to utilize
the TPM security component.
WARNING!
Ensure that the system is powered off and all power sources are disconnected
from the server prior to performing this procedure.
Voltages are present at various locations in 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.
Removing the TPM
To remove the TPM, follow these steps:
1.
Back up the current TPM settings. See the HP-UX operating system documentation for more
information.
2.
Power off the server and disconnect the power cables. See
“Powering On and Powering Off
the Server” (page 78)
.
3.
If rack mounted, slide the server completely out from the rack. See
“Extending the Server
from the Rack” (page 143)
.
