1.10.4 LAN Subsystem Software
LAN software and drivers are available from Intel’s World Wide Web site.
For information about Refer to
Obtaining LAN software and drivers Section 1.3, page 17
1.11 Hardware Management Subsystem
The hardware management features enable the Desktop Boards to be compatible with the Wired
for Management (WfM) specification. The Desktop Board has several hardware management
features, including the following:
•
Fan monitoring and control (through the hardware monitoring and fan control ASIC)
•
Thermal and voltage monitoring
•
Chassis intrusion detection
1.11.1 Hardware Monitoring and Fan Control ASIC
The features of the hardware monitoring and fan control ASIC 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
