The diagram below shows the location of the various temperature sensors:
Figure 2.12 Thermal Sensor Locations
2.4.9.1 Electronic Label: FRU EEPROM
The FWA-1320 supports an onboard FRU EEPROM which can be accessed via
SMBus 0 using afru.
Alternatively, FRU information is also embedded in DMI Tables 1/2/3 and can be dis-
played with DMI parsing tools like dmidecode.
2.5 Advanced Platform Features
2.5.1 Intrusion Detection
The FWA-1320 does not support intrusion detection by default. This feature has been
reserved in the motherboard design, though, and can be enabled at system level via
customization. Please contact your Advantech representative should you be inter-
ested in this option.
2.5.2 Watchdog
The FWA-1320 provides a programmable watchdog that may be used to reset the
system in case it bites due to malfunctioning application software to restore the unit
to a known good state. The watchdog is based on intel’s TCO timer and is integrated
in the Atom C2000 device. The TCO watchdog timer is supported under Linux via a
kernel driver (iTCO_wdt.ko). Please refer to Linux as well as ATOM C2000 documen-
tation should you need more details.
2.5.3 LAN Bypass
For a detailed description of the LAN Bypass functionality and the related software
API, please refer to the Advanced LAN Bypass User’s Manual.
