Board Connectors 

The board connectors can be divided into three groups: 

• 

Back panel connectors 

• 

Midboard connectors 

— 

Audio connectors 

— 

Power and hardware connectors 

— 

Add-in board and peripheral interface connectors 

• 

Front panel connectors 

 CAUTION 

Many of the midboard and front panel connectors provide operating voltage (+5 V DC and 
+12 V DC, for example) to devices inside the computer chassis, such as fans and internal 
peripherals.  These connectors are not overcurrent protected.  Do not use these connectors for 
powering devices external to the computer chassis.  A fault in the load presented by the external 
devices could cause damage to the computer, the interconnecting cable, and the external devices 
themselves.
