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.
Power Fail Header
Connect a cable from your power sup-
ply to the Power Fail header to provide
you with warning of a power supply
failure. The warning signal is passed
through the PWR_LED pin to indicate
a power failure. See the table on the
right for pin defi nitions.
Fan Headers
The X6DHT-G 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: 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 on the
motherboard. Do not use 3-pin fans
and 4-pin fans together.
