Pin Definitions (USB2/3, USB4/5)

Four additional USB headers (USB2/3 and USB4/5) are included on the serverboard. These may be used for front side access. A USB cable (not included) is needed for the connec- tion. See the table on the right for pin defi nitions.

Fan Headers

The PDSMU has six fan headers, des- ignated Fan1 through Fan6. All are 4-pin fans to provide a Pulse Width Modulated (PWM) signal, however pins 1-3 of the headers are backward compatible with traditional 3-pin fans. Connect the CPU heatsink fan and the system (chassis) fans to these headers. Their speed is controlled via Thermal Management with a BIOS setting. See the tables on the right for pin defi nitions.

Note: Pin 10 is included on the header but not on the port. NC indicates no connection.

Note: When using Thermal Management set- tings, please use all 3-pin fans or all 4-pin fans. Please do not use both 3-pin fans and 4-pin fans together.
