D201GLY2 Technical Product Specification

Product Description

1.10 Hardware Management Subsystem

The hardware management features enable the board to be compatible with the Wired

for Management (WfM) specification. The Winbond W83627DHG-B I/O controller is

used to implement hardware monitoring and fan control. The features of this 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 four voltages (+5 V, +V_1P8_CORE, +VCCP, and

+12 V) to detect levels above or below acceptable values

• Thermally monitored closed-loop fan control, for system fan, 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.
