2.1.3 Temperature monitoring
Sensors monitor temperature values in many different areas in the APC910. The locations of the temperature
sensors can be seen in "Figure 4: Temperature sensor locations" on page 22. The values listed in "Table 6:
Temperature sensor locations" on page 22 represent the defined maximum temperature

for the respective
measurement point. An alarm is not triggered if this temperature is exceeded. These temperatures can be read in
BIOS or in approved Microsoft Windows operating systems via the B&R Control Center.
Additionally, the hard disks for APC910 systems available from B&R are equipped with S.M.A.R.T, or Self Moni-
toring, Analysis, and Reporting Technology. This makes it possible to read various parameters, for example the
temperature, using software (e.g. HDD thermometer - freeware) in approved Microsoft operating systems (except
Windows CE).

can be read in
BIOS (menu item Advanced - OEM Features - System Board Features / CPU Board Features - Temperature
Values) or in Microsoft Windows operating systems via the B&R Control Center

.
For applications that don't use Windows, the temperatures can be evaluated using the B&R implementation guide.
In addition to the implementation guide, there are also MS-DOS sample programs available.
