10.3  Higer Power Common Redundant Power Distribution Board (PDB) 
The Power Distribution Board (PDB) for the Intel
®
 Server Chassis P4000M supports the 
Common Redundant power supply in a 1+1 redundant configuration. The PDB is designed to 
plug directly to the output connector of the PS and it contains 3 DC/DC power converters to 
produce other required voltages: +3.3VDC, +5VDC, and 5V standby along with additional over 
current protection circuit for the 12V rails.  
The Intel
®
 Server Chassis P4304XXMUXX family includes this PDB.
