Fan Headers
The X7DBE/X7DB8 has eight fan
headers, designated Fan1 through
Fan8. Fan speed is controlled via
Thermal Management with a BIOS
setting. See the table on the right for
pin defi nitions.
Note:
Fans 5-8 are 4-pin fans. Pins
1-3 of the fan headers are backward
compatible with traditional 3-pin fans.
The onboard fan speed is controlled
by a BIOS setting. When using a
Thermal Management setting, use all
3-pin fans or all 4-pin fans (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.
