ATX Power Connector
The main power supply connector
(JPW1) on the PDSM4/PDSME meets
the SSI (Superset ATX) specifi cation.
Make sure that the orientation of the
connector is correct. You must also
use the 8 pin (JPW2) power connec-
tor 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.
