report a configuration modification, including memory capacity or number of memory cards change, hard disk drive change, optical
device or processor change. These changes will also generate a configuration change signal, transmitted to the DASH or DMI agent.
4.15 Replacing the system battery
In all CIARA Astro SN-170T models the battery is a standard 3.3 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 micro PC 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 micro PC. Disconnect the micro PC’s power cord from
the AC power source (wall outlet or power adapter).
3. Remove the micro PC 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 micro PC cover.
4.16 Installing an upgrade CPU
All CIARA Astro SN-170T 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 Astro SN-170T
models use exclusively LGA1150 processor technologies and are not compatible with other types of processors.
