Jumper Settings for Processor Fan Failure Detection
Jumper JP5
Processor Fan Failure Detection Setting
The 686IPK system board supports processor fan “failure detection”
function. Make sure your processor fan also supports this function. To
enable this function, set JP5 to On. You will hear music if your fan fails
to function. If your processor fan is less than 3600 RPM or does not
support the “failure detection” function, leave JP5 in its default setting.
Please note - the connector on your fan must be a 3-pin connector and
the third pin an “open collector” type. Connect the 3-pin connector to J4.
Factory Testing Jumpers
The jumpers below are for factory testing only and should always be set
to their default configuration. Reconfiguring these jumpers will cause
problems with your system board.
JP4: Off
JP6: 1-3, 2-4 On
