Ac/Dc Power Connector (Cn3, Cn17); Power Switch; I/O Voltage Selection - Advantech MIC-3043 User Manual

3.5.1 AC/DC Power Connector (CN3, CN17)

These connectors accept the separate AC/DC power input.
Note: The power connector CN17 is not compatible with
ATX pin assignment. Do not use an ATX power
supply instead of DC power supply.

3.5.2 Power Switch

This connector provides power control over the plug-in power module. If
the CompactPCI chassis provides a 2-pin power switch cord, connect this
cord to the CN15 connector to control the power by the power switch.
3.5.3 V I/O Voltage Selection
This jumper is used to select the V I/O voltage. The backplane allows
V I/O to be set to either 5 V or 3.3 V. Since the default is configured for
use with 5V 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).
