3.5.1 AC/DC Power Connector (CN3, CN17)
These connectors accept the separate AC/DC power input.
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).

Note:
The power connector CN17 is not compatible with 
ATX pin assignment. Do not use an ATX power 
supply instead of DC power supply.
