Power Button
To control the system with a power button a switch may be connected to the pins 5-6 of
connector. The PWR_BTN# signal is low-active and is connected directly to the
corresponding pin of the Qseven
TM
module.
LID Button
To make use of the LID signal, a switch may be connected to the pins 7-8 of the
connector. The LID_BTN# signal is low-active and is connected directly to the corresponding
pin of the Qseven
TM
module.
Suspend Signal
The SUS_S3# and SUS_S5# signals are also available on pin9 and pin10 respectively of the
connector. These signals are low-active and are connected directly to the
corresponding pins of the Qseven
TM
module.
S3 Cold/ S3 Hot Feature (J1102)
The MSC Q7 MB EP6 board provides power saving feature in S3 (Suspend to RAM) mode.
Two separate jumper options are provided on J1101 in order to choose either for S3-cold or
S3-hot for both baseboard and the Q7 module. The jumper option can be set to ensure
minimum power consumed by system in S3 state.

12V SATA and Fan Voltage
An on board voltage regulator is used to provide 12V for the SATA and Fan. The voltage
regulator delivers 12V (1A max) when 15V < VCCIN < 28V. (See also 3.22.1 12V LVDS
Backlight)
When the input is 12V, this input voltage can be directly coupled to the SATA power
connector and Fan voltage selector J901. A jumper J1302 is provided to enable this.
