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).

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.

Note
If the conga-HPC/EVAL-Client 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. Only works in ATX mode. AT mode does not support this feature.
