!Computer mainboards and components contain very delicate IC chips. To protect them
against damage caused from electric static, you have to follow some precautions:
• Unplug your computer when you work inside.
• Hold components by the edge, don't touch their leads.
• Use a grounded wrist strap.
Place the mainboard and the components on a grounded antistatic pad whenever you
work outside the computer.
Once you have installed the system board, you should remove the battery protection (i.e.
the thin plastic plate between battery and contact spring).

Temperature monitoring / system monitoring
One goal of temperature and system monitoring is to reliably protect the computer hardware against
damage caused by overheating. In addition, any unnecessary noise is also to be prevented with a
reduced fan speed, and information is to be provided on the system state. The cover monitoring is
used to protect the system against unauthorized opening.
The temperature and system monitoring are controlled by an onboard controller developed by
Siemens.
The following functions are supported:
Temperature monitoring:
Measurement of the processor temperature and the system temperature with an
onboard temperature sensor, measurement of the external temperature with an
optional I²C temperature sensor.
Temperature control:
The temperature is controlled with the fan speed and/or by reducing the clock
frequency of the processor. The clock frequency of the processor is dependent on
the setting in the BIOS setup. Temperature dependent regulation of processor speed
enables reduced fan rotation speed which means less noise.
Fan monitoring:Removed, blocked or sticky fans are detected. Blocked or sticky fans are operated
with 12 V pulse voltage. Fans removed while the system is switched off are signaled
by the Display news LED when the system is switched on again and processed by the
BIOS or the application.
Fan control: The fan speed of the power supply fan and fan 1 is controlled in dependence on the
temperature.
Sensor monitoring:
A fault or removal of a temperature sensor is detected. In this case all affected fans
runs at maximum speed to achieve the greatest possible protection of the hardware.
Temperature sensors removed while the system is switched off are signaled by the
Display news LED and processed by the BIOS or the application.
Cover monitoring:
Unauthorized opening of the cover is detected, even when the system is switched
off. However, this will not be indicated until the system is operating again.
Voltage monitoring:
The voltages 12 V, 5 V and the CMOS battery are monitored.
With hardware monitoring - regardless of the operating system and processor - the advantages
compared to conventional software monitoring are clear:
− suitable for all operating systems and processor types
− no additional load on processor (performance)
− optimum reliability, even if process faults or faults are present in the operating system
− optimum noise reduction
Three different operating modes are available and can be configured in the BIOS Setup: Auto, Silent
and Enhanced Cooling.
