Fan Monitoring; Chassis Intrusion And Detection - Intel D845GRG Using Manual

1.12.1.2 Hardware Monitoring and Fan Control ASIC
The features of the hardware monitoring and fan control ASIC (Analog Devices ADM1027,
National Semiconductor LM85, Standard Microsystems SMSC EMC6D101, or equivalent)
include:
•
Internal ambient temperature sensor
•
Two remote thermal diode sensors for direct monitoring of processor temperature and ambient
temperature sensing
•
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 V, +2.5 V, and +VCCP1) to
detect levels above or below acceptable values
•
Fan monitoring for all three fans
•
Thermally monitored closed-loop fan control, for all three fans, that can adjust the fan speed or
switch the fans on or off as needed
•
SMBus interface

1.12.2 Fan Monitoring

Fan monitoring can be implemented using Intel
Manager, or third-party software. The level of fan monitoring and control is dependent on the
hardware monitoring ASIC used

The functions of the fan connectors

1.12.3 Chassis Intrusion and Detection

The Desktop Boards support a chassis security feature that detects if the chassis cover is removed.
For the chassis intrusion circuit to function, the chassis' power supply must be connected to AC
power. The security feature uses a mechanical switch on the chassis that attaches to the chassis
intrusion connector. The mechanical switch is open for normal computer operation.
✏
NOTE
Chassis intrusion detection may be implemented using Intel LANDesk Client Manager or third-
party software.
