2-6 Connectors and Headers
ATX Power Connector
The main power supply connector
(JPW1) on the PDSMi-LN4 meets the
SSI (Superset ATX) specifi cation.
You can only use a 24-pin power sup-
ply cable on the motherboard. Make
sure that the orientation of the con-
nector 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.
