4.1.5 Power-Up Control
The module's SUS_S3# signal controls the ATX power supply control signal (PS_ON#). When the system goes to Suspend to RAM (S3) or
Soft Off (S5), the module's chipset asserts the 'SUS_S3#' signal. Through the use of an inverter, the low active 'PS_ON#' signal goes high and
switches off the ATX power supply.
When the system is in a power-down system state, any system wake-up event invokes the chipset of the module to deassert the 'SUS_S3#'
signal. With the deassertion, the system transitions to Full-On state (S0).
4.1.6 Module Type Detection
The signals TYPE0, TYPE1, and TYPE2 indicate the pinout type of the module connected to the carrier board. These pins are either open (NC)
or strapped to ground (GND) by the module as shown in the table below.
Table 15 Module Type Detection Pinout Description
TYPE2 TYPE1
N.C N.C
N.C N.C
N.C GND
N.C GND
GND N.C
GND N.C
GND GND
GND GND
Note
1. If the conga-HPC/uATX-Server detects an incompatible module pinout, an onboard logic prevents the board from powering up the whole
system by controlling the 'PS_ON#' signal of the ATX power supply. This feature works only in ATX mode.
2. Pin header X56 is for congatec internal use only.
