Serial Ports

The COM1 serial port is located on the IO backplane. COM2 is a header on the serverboard (see serverboard layout for location). See the table on the right for pin defi nitions.

Fan Headers

The X7DBU has fi ve eight headers, designated Fan1 through Fan8. FAN5 through FAN8 are for 4-pin Pulse Width Modulated (PWM) fans and are to be connected to the CPU heatsink fans. Their speed is controlled via Thermal Management with a BIOS setting. FAN1 through FAN4 are 3- pin, non-PWM fans. See the tables on the right for pin defi nitions.
