4-3 Motherboard RAS Functions

The NSA-series Industrial PC can read standard PC RAS data (voltage,
temperature, fan rpm). It also has additional unique RAS functions, such as POST
error logging, POST error retry, and CMOS data recovery.

4-3-1 Standard PC RAS Data

The NSA-series Industrial PC can read the following standard PC RAS data.
No.
CPU temperature
1
sensor
No. of fan rotations
2
(See note.)
3 Board voltage
4 POST error logs
Note: The NSA-series Industrial PC does not have a fan.
Although the NSA-series Industrial PC will read RAS data from the super I/O chip
Note
(SMSC LPC47M192) and the chipset (Intel 855GME+Intel 6300ESB) on the
motherboard, it does not do conversions, such as converting to degrees of
temperature. Refer to respective datasheets for data processing (data conversion)
details.

4-3-2 Unique RAS Functions

POST Error Log
When POST errors occur, the 4-byte POST error code, time, month, and date for
up to 32 errors are logged as individual POST error records. These records can
be read from the BIOS setup menu.
Error data can be retained indefinitely without relying on the internal battery for
backup because POST error logs are saved in the motherboard EEPROM. This
also means that error data can only be deleted from the BIOS setup menu.
Note: After 32 errors, the most recent error will overwrite the oldest error.
Individual error records cannot be deleted. If you delete one error record, they will
all be deleted.
Monitored
hardware data
Temperature data read via the SMBus interface
(hardware monitor interface). (Not converted to degrees
centigrade)
Fan rpm (2 fans) and the fan log (per fan) read via the
SMBus interface (hardware monitor interface). (Not
converted to rotations per minute)
Voltages read via the SMBus interface (hardware monitor
interface). The following voltages can be read.
HVCC (3.3 V)
V12 (+12 V)
V5 (+5 V)
VTR (3.3 V)
V25 (+2.5 V)
Vccp
V18 (+1.8 V)
V15 (+1.5 V)
(Not converted to voltage)
BIOS startup log data (approximately 40 bytes for the 10
most recent errors) read from specified CMOS
addresses in the chipset.
