Tolerance Description
TYPE[0:2]# PDS The TYPE pins indicate to the Carrier Board the Pin-out Type that is
implemented on the module. The pins are tied on the module to either
ground (GND) or are no-connects (NC). For Pin-out Type 1, these pins
are don’t care (X).
TYPE2# TYPE1# TYPE0#
X X X Pin-out Type 1
NC NC NC Pin-out Type 2
NC NC GND Pin-out Type 3 (no IDE)
NC GND NC Pin-out Type 4 (no PCI)
NC GND GND Pin-out Type 5 (no IDE, no PCI)
The Carrier Board
should implement combinatorial logic that monitors
the module TYPE pins and keeps power off (e.g deactivates the
ATX_ON signal for an ATX power supply) if an incompatible module
pin-out type is detected. The Carrier Board logic
may also implement a
fault indicator such as an LED.
Power and GND Pin

Tolerance Description
VCC_12V Power Primary power input: +12V nominal. See Electrical Specifications
section for allowable input range. All available VCC_12V pins on
the connector(s)
shall be used.
VCC_5V_SBY Power Standby power input: +5.0V nominal. See Electrical
Specifications section for allowable input range. If VCC5_SBY is
used, all available VCC_5V_SBY pins on the connector(s)
shall
be used. Only used for standby and suspend functions. May be
left unconnected if these functions are not used in the system
design.
VCC_RTC Power Real-time clock circuit-power input. Nom3.0V. See
Electrical Specifications section for details.
GND Power Ground - DC power and signal and AC signal return path.
All available GND connector pins
shall be used and tied to
Carrier Board GND plane.
