Universal Serial Bus
Headers
Three additional USB headers (USB2/
USB3 and USB4) 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.

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 eight headers, des-
ignated 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.
