Fan Headers
The X7DWU has eight headers, des-
ignated Fan1 through Fan8. FAN7
and FAN8 are for the CPU heatsinks.
These 4-pin fan headers are for Pulse
Width Modulated (PWM) fans and
their speed is controlled via Thermal
Management with a BIOS setting.
See the tables 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.
Note:
Pin 10 is included on the header but not on
the port. NC indicates no connection.
