Required Connection
Note 1: The 12V DC input is limited to 12A by design. It provides up to 144W power input to
the motherboard. Please keep onboard power use within the power limits specified above.
Over-current DC power use may cause damage to the motherboard.
Note 2: Do not use the 4-pin DC power at JPW2 when the 24-pin ATX Power at JPW1 is
connected to the power supply. Do not plug in both JPW1 and JPW2 at the same time..

3.2 Headers and Connectors

Fan Headers
There are two 4-pin fan headers on the motherboard. Although pins 1-3 of the fan headers
are backward compatible with the traditional 3-pin fans, we recommend you use 4-pin fans to
take advantage of the fan speed control via Pulse Width Modulation through the BMC. This
allows the fan speeds to be automatically adjusted based on the motherboard temperature.
External Speaker
The JD2 header is for the external speaker. If you wish to use an external speaker, connect
its cable to pins 1-4.
