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.
