9.1 9.1 Overview
The following individual functions are implemented:
• Temperature monitoring and over/under temperature indication
• Watchdog
• Fan monitoring
Messages can be output from the monitoring modules to the applications.
The SOM software (Safecard On Motherboard) and DiagMonitor software on CD (optional)
are available for this.
The DiagMonitor software CD contains the monitoring software, the software for the stations
to be monitored, and a library for creating user-specific applications.
The description of the driver and SOM program are available on the CD "Documentation and
Drivers" under Drivers & Updates\<device>\...
9.2 9.2 Temperature monitoring
Temperature monitoring
The temperature is recorded by means of three thermocouples. One thermocouple monitors
the processor temperature, another the temperature in the area near the power supply, and
a third the air intake temperature next to the DVI interface.
When the temperature is out of the range of one of the three set temperature thresholds, the
following error reactions are triggered:
Reaction Option
Device and CPU fans accelerate to maximum
speed.
None
SOM or DiagMonitor- software is activated None
The temperature error is retained until the temperatures have fallen below the thresholds
and are reset by one of the following measures:
• Error acknowledgement in the SOM program (manually by means of the broom icon)
• Restart of the device.
