DMIC connector (4-pin DMIC)
The DMIC connector is for connecting the digital microphone
module used in All-in-One chassis.
Chassis intrusion header (4-1 pin CHASSIS)
This header is for a chassis-mounted intrusion detection sensor
or switch. Connect one end of the chassis intrusion sensor or
switch cable to this header. The chassis intrusion sensor or
switch sends a high-level signal to this header when a chassis
component is removed or replaced. The signal is then generated
as a chassis intrusion event.
By default, the pin labeled "Chassis Signal" and "Ground" are
shorted with a jumper cap. Remove the jumper caps only when
you intend to use the chassis intrusion detection feature.
Front panel audio connector (10-1 pin
AAFP)
This connector is for a chassis-mounted
front panel audio I/O module that supports
either HD Audio or legacy AC`97 audio
standard. Connect one end of the front
panel audio I/O module cable to this
connector.
Internal stereo speaker header (4-pin SPK_OUT)
The internal mono speaker header allows connection to an
internal, low-power speaker for basic system sound capability.
The subsystem is capable of driving a speaker load of 4 Ohms at
3 Watts (rms).
