3. Ensure the battery is carefully removed. This is performed by holding the battery socket
stationary with one hand while tilting the battery away from the battery socket using the other
hand. See Figure 77
CAUTION: Ensure the battery socket is secured and stationary when tilting the battery out
of or into the battery socket. If the socket is not held firmly, the socket solder joint could crack
and separate from the board surface, rendering your system inoperable.

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.
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. Replacing a failed TPM must be performed
by an HP CE, but a customer can move the TPM from a failed system board to a new system board.
The fundamental capabilities of the TPM include:
• Platform authentication
• Sensitive information protection
• Data integrity
• System privacy
