2. Fan Connectors
There are two fan connectors on the
P6F104 mainboard for the cooling fans.
The connectors support fans of 12V DC/
500mAMP (6 WATT) or less. When the
system goes into sleep state, fan should be
shut down to eliminate audible noise and
reduce power consumption.
3. IrDA-compliant IR (Infrared) Connector
This 5-pin connector connects to an
wireless transmitting and receiving
infrared module via a cable and a
bracket connect to back panel. This
cable and mounting bracket should
come with the IrDA modules.
4. Floppy Drive Connector (One 34-pin Block)
A floppy disk drive ribbon cable has 34
wires and 2 connectors to support 2
floppy disk drives. The connector with
twisted wires always connects to drive
A, and the connector with untwisted
wires connects to drive B. You must
orient the cable connector so that the
pin 1(color) edge of the cable is at the
pin 1 of the I/O port connector.
