1.10 Hardware Management Subsystem
The hardware management features enable the board to be compatible with the Wired for
Management (WfM) specification.
The SMSC SCH5017 I/O controller is used to implement
hardware monitoring and fan control.
The features of the SMSC SCH5017 I/O controller 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 VSB, +1.5 V, and +VCCP) to
detect levels above or below acceptable values
•
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
1.10.1
Fan Monitoring
Fan monitoring can be implemented using Intel
®
Desktop Utilities, LANDesk* software, or third-
party software.
For information about
Refer to
The functions of the fan connectors
Section 1.11.2.2, page 27
1.10.2
Chassis Intrusion and Detection
The board supports a chassis security feature that detects if the chassis cover is removed.
The
security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion
connector.
When the chassis cover is removed, the mechanical switch is in the closed position.
For information about
Refer to
The location of the chassis intrusion connector
