4.12 Trusted Platform Module (TPM)
The TPM module version 2.0 component is specifically designed to enhance platform security above-and-beyond the capabilities of
today’s software by providing a protected space for key operations and other security critical tasks. Using both hardware and
software,
the TPM protects encryption and signature keys at their most vulnerable stages
—
operations when the keys are being used
unencrypted in plain-text form. The TPM shields unencrypted keys and platform authentication information from software-based
attacks.
NOTE
The Intel
®
TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic counters. One major function of the monotonic
counters is for anti-replay protection of the internal Intel
®
TPM data. If the battery is removed or exhausted, the Intel
®
TPM data will
be deleted in accordance with Trusted Computing Group guidelines. Please back-up TPM keys and data before removing the battery.
4.13 Replacing the system battery
In all CIARA Horizon D10500 / T10500 models the battery is a standard 3 V Lithium battery model CR-2032. This type of battery should
last at least 3 years, if the system is not in use. When the computer is plugged in, the standby current from the power supply extends
the life of the battery. If the battery wears out, your system will no longer retain BIOS information when turned off. For example, you
will get a message stating that the time and date are invalid. If this happens, you should replace the battery, or call your CIARA service
representative.
CAUTION :
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same type as recommended by CIARA. The
disposal of used batteries is subject to environment issues and we recommend that this work be done by a qualified CIARA technician
who will dispose safely of the used battery.
NOTE
The Intel TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic counters. One major function of the monotonic
counters is for anti-replay protection of the internal Intel TPM data. If the battery is removed or exhausted, the Intel TPM data will be
deleted in accordance with Trusted Computing Group guidelines. Please back-up TPM keys and data before removing the battery.
To replace the battery, follow these steps :
1. Observe the precautions.
2. Turn
off all peripheral devices connected to the computer. Disconnect the computer’s power cord from
the AC power source (wall outlet or power adapter).
3. Remove the computer cover.
4. Locate the battery on the board.
5. With a medium flat-bladed screwdriver, gently pry the battery free from its connector.
Note the orientation of the “+” and “
-
” on the battery.
6. Install the new battery in the connector, orienting the “+” and “
-
” correctly.
7. Replace the computer cover.
4.14 Installing an upgrade CPU
All CIARA Horizon D10500 / T10500 models may be enhanced by the installation of a higher performing CPU. Since this upgrade
necessitates a lot of care and attention, it should be carried out by a CIARA authorized service centre. Please take a note that the
CIARA Horizon D10500 / T10500 models use exclusively LGA1150 processor technologies and are not compatible with other types of
processors.
