Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification
46
1.13 Hardware Management Subsystem
The hardware management features enable the board to be compatible with the Wired for
Management (WfM) specification. The board has several hardware management features,
including the following:
• Hardware monitoring
• Chassis intrusion detect connector (optional)
• Fan control and monitoring (implemented on both the SMSC LPC47M132 and optional SMSC
LPC47M142 I/O controllers)
For information about Refer to
The WfM specification Table 4, page 19
Fan control functions of the SMSC LPC47M132 and
optional SMSC LPC47M142 I/O controllers
Section 1.13.2, page 46
1.13.1 Hardware Monitor Component
The hardware monitor component provides low-cost instrumentation capabilities. The features of
the component include:
• Internal ambient temperature sensing
• Remote thermal diode sensing for direct monitoring of processor temperature (if supported in
the processor)
• Power supply monitoring (+12 V, +5 V, +3.3 V, +2.5 V, 3.3 VSB, and V
CCP) to detect levels
above or below acceptable values
• SMBus interface
1.13.2 Chassis Intrusion Detect Connector (Optional)
The board supports a chassis security feature that detects if the chassis cover is removed. For the
chassis intrusion circuit to function, the chassis’ power supply must be connected to AC power.
The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion
detect connector. The mechanical switch is closed for normal computer operation. Chassis
intrusion detection can be supported with third party SMBus software.
For information about Refer to
The location of the optional chassis intrusion detect connector Figure 14, page 69
