6.19 Power Jumper Settings

CNY6:
PWR_OK Config
CNY7:
Power Up Config
*The Super I/O detects a power button event using the 'PSIN' pin. When a power button event occurs, the power-
up logic of the Super I/O sets 'PSOUT#' low and asserts 'PWRBTN#' of the module's chipset. The Super I/O also
sets the 'PWRCTL#' pin to low, which asserts the 'PS_ON#' signal and switches on the ATX power supply.
JPY1:
AT/ATX MODE
In AT mode, JPY1 shorts PS_ON# to ground
directly to force power on.
JPY10: PS_ON# Signal Source
All ADLINK modules support S3 mode and
consecutive power down of ATX power supply.
For modules that connect the S3 signal, PS_ON#
should always be set to SUS_S3# as source (even when S3 mode is disabled in the BIOS). For
modules that do not bring out the S3 signal, PS_ON# should be set to SUS_S5# as source.
JPZ3:
AT Power 5V Setting
With an AT power supply is connected to
the Express-BASE, JPZ3 can be used to
provide 5VSB to the COM module from
the carrier board.
