Fan Connectors
Two fan connectors are provided, Fan 1 is recommended for the CPU heat-sink fan,
Fans 2 can be used for any other case or heat-sink fan, however fan 2 does not have
the fan speed monitoring capability.
The pin assignment for these connectors are as follows:
Pin 1 – Ground.
Pin 2 - +12V.
Pin 3 – Sensor
Main Power Connector
When used with an ATX-compliant power supply that supports remote power on/off, the
motherboard can turn off the system power through software control.
To enable soft-off control in software, advanced power management must be enabled
in the Setup program and in the operating system. When the system BIOS receives the
correct APM command from the operating system, the BIOS turns off power to the
computer.
With soft-off enabled, if power to the computer is interrupted by a power outage or a
disconnected power cord, when power resumes, the computer returns to the power
state it was in before power was interrupted (on or off).
Management Extension Hardware
The optional Management Extension component (Analog Device AMD9240A) provides
the instrumentation capabilities designed to reduce the total cost of owning a PC when
used with Intel LANDesk Client Manager. Feature include:
• Integrated temperature monitoring.
• Fan speed monitoring.
• Power supply voltage monitoring to detect levels above or below acceptable values.
• Registers for storing POST hardware test results and error codes.
• Chassis Intrusion - This is carried out by the installation of a light sensitive device on
the motherboard (close to the BIOS). This will detect the presence of light if the
chassis cover is removed. Alternatively, a header (close to the BIOS) is installed on
the motherboard for the connection of a micro switch to detect chassis intrusion.
When suggested ratings for temperature, fan speed, or voltage are exceeded, an
interrupt is activated to report the status.
