Fan Headers
The X7DB8+ has eight fan headers,
designated Fan1 through Fan8. Fan
speed is controlled via Thermal Man-
agement with a BIOS setting. See the
table on the right for pin defi nitions.
Note: Fan1-4 are 3-pin fans and
Fan5-8 are 4-pin fans. Pins 1-3 of
the 4-pin fan headers are backward
compatible with traditional 3-pin fans.
When using a Thermal Management
setting, use all 3-pin fans or all 4-pin
fans on the serverboard. Do not use
3-pin fans and 4-pin fans together.
Serial Ports
The COM1 serial port is located beside
the mouse port. 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.
