Table 31 Rapid Shutdown Signal Descriptions - Congatec COM Express conga-TCV2 User Manual

Signal Pin # Description
PWR_OK B24 Power OK from main power supply. A high value indicates that the power is
good
SUS_STAT# B18 Indicates imminent suspend operation; used to notify LPC devices
SUS_S3# A15 Indicates system is in Suspend to RAM state.
Active-low output. An inverted copy of SUS_S3# on the carrier board (also
known as "PS_ON") may be used to enable the non-standby power on a typical
ATX power supply.
SUS_S4# A18 Indicates system is in Suspend to Disk state. Active low output
SUS_S5# A24 Indicates system is in Soft Off state
WAKE0# B66 PCI Express wake up signal
WAKE1# B67 General purpose wake up signal
May be used to implement wake-up on PS/2 keyboard or mouse activity
BATLOW# A27 Battery low input
This signal may be driven low by external circuitry to signal that the system
battery is low, or may be used to signal some other external power-
management event.
LID# A103 Lid button used by the ACPI operating system for a LID switch
Note: For proper detection, assert a pulse width of at least 16 ms.
SLEEP# B103 Sleep button used by the ACPI operating system to bring the system to sleep
state or to wake it up again
Note: For proper detection, assert a pulse width of at least 16 ms.
