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


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 voltages (+5 V, +12 V, +3.3 V, Vbat 3.3, Vcore1

and Vcore2) to detect levels above or below acceptable values

• Thermally monitored closed-loop fan control, for all fans, that can adjust the

fan speed as needed.

• SMBus

interface
