1U Rackmount System
XHardware Health Configuration
This feature allows the user to monitor Hardware Health of the system and review the status of each
item when displayed.
CPU Overheat Alarm
This option allows the user to select the CPU Overheat Alarm setting which determines when the CPU
Warning:
1.Any temperature that exceeds the CPU threshold tempera- ture predefined by the CPU manufacturer
may result in CPU overheat or system instability. When the CPU temperature reaches this predefined
threshold, the CPU and system cooling fans will run at full speed.
2. To avoid possible system overheating, please be sure to provide adequate airflow to your system.
The options are:
o The Early Alarm: Select this setting if you want the CPU overheat alarm (includ- ing the LED and the
buzzer) to be triggered as soon as the CPU temperature reaches the CPU overheat threshold as
predefined by the CPU manufacturer.
o The Default Alarm: Select this setting if you want the CPU overheat alarm (including the LED and the
buzzer) to be triggered when the CPU temperature reaches about 5oC above the threshold tempera-
ture as predefined by the CPU manufacturer to give the CPU and system fans additional time needed
for CPU and system cooling. In both the alarms above, please take immediate action as shown below.
CPU 1 Temperature/ CPU 2 Temperature/ System Temperature
This feature displays current temperature readings for the CPU and the System. The following items
will be displayed for your reference only:
CPU 1 Temperature/CPU 2 Temperature
The CPU thermal technology that reports absolute temperatures (Celsius/Fahren- heit) has been
upgraded to a more advanced feature by Intel in its newer processors. The basic concept is each CPU
is embedded by unique temperature information that the serverboard can read. This 'Temperature
Threshold' or 'Temperature Tolerance' has been assigned at the factory and is the baseline on which
the serverboard takes action during different CPU temperature conditions (i.e., by increasing CPU
Fan speed, triggering the Overheat Alarm, etc). Since CPUs can have different 'Tem- perature Toler-
ances', the installed CPU can now send information to the serverboard what its 'Temperature Toler-
ance' is, and not the other way around. This results in better CPU thermal management.
