Intel Desktop Board D815EFV/D815EPFV Technical Product Specification
1.13.3 Fan Control and Monitoring
1.14 CNR Connector (Optional)
✏
46
The SMSC LPC47M132 I/O controller and the optional SMSC LPC47M142 I/O controller both
provide fan tachometer input for the processor fan (fan 1) and system fan (fan 2) and fan control
output for the system fan (fan 2) and the chassis fan (fan 3). Monitoring and control can be
implemented using third-party software.
The CNR connector supports the audio, modem, USB, and LAN interfaces of the Intel 815E and
Intel 815EP chipsets. Figure 10 shows the signal interface between the riser and the ICH2.
NOTE
The USB interface from the ICH2 to the CNR is optional on this board.
The interfaces supported by the CNR connector include (but are not limited to) the following:
