2.5.2 ATX Power Connector (ATXPW1 )
This connector accepts one standard ATX power supply.
Note: Do not use ATX power supplies and plug-in power modules at
the same time.
2.5.3 Power Connectors for Peripherals (CN3 and
CN4)
The CN3 and CN4 connectors provide power to the peripherals, such
as hard disk drives or floppy disk drives.
2.5.4 Power Inlet and Ground Screw Terminals
(T1~T5)
These screw terminals accept AC or DC power input. T1 ~ T5 provides
power to CN6 and CN7. Depending on the input requirement (AC or
DC) of the plug-in power modules intended for CN6 and CN7,
connect either AC or DC source power.
2.5.5 V I/O Voltage Selection (JP1)
This jumper is used to select the V I/O voltage. MIC-3401/
MIC-3401H allows V I/O to be set to either 5 V or 3.3 V. Connect the
two pins labeled "+5 V" with a cap to set V I/O to 5 V , and connect the
two pins labeled "+3.3 V" with a cap to set V I/O to 3.3 V. Since the
MIC-3401/MIC-3401H default is configured for use with 5 V
CompactPCI boards (blue keyed connectors), once the jumper is set
to 3.3 V, the CompactPCI keys must be changed to 3.3 V at the same
time (as yellow keyed connectors). Please contact Advantech for
detail.
