2-6 Connectors and Headers
ATX Power Connector
The main power supply connector
(JPW1) on the PDSML-LN1/PDSML-
LN2 meets the SSI (Superset ATX)
specifi cation. You can only use a 24-
pin power supply cable on the mother-
board. Make sure that the orientation
of the connector is correct. You must
also use the 8-pin (JPW2) processor
power connector for adequate power
supply to the system (below.) See the
table on the right for pin defi nitions.
Processor Power Connector
In addition to the Primary ATX power
connector (above), the 12V 8-pin Pro-
cessor connector at JPW2 must also
be connected to your power supply
to provide adequate power supply to
the system.
