Product Description

1.13 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

1.13.1Hardware 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
