Internal connectors
1.
Serial port connector (10-1 pin COM)
This connector is for a serial (COM) port. Connect the serial port module cable to this
connector, then install the module to a slot opening at the back of the system chassis.
The COM module is purchased separately.
Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan of
maximum 1A (12 W) fan power.
2.
CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN 1/2)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector
