2.8 Connectors

CAUTION

Only the following connectors have overcurrent protection: back panel USB, front panel USB, and PS/2.

The other internal connectors are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves.

This section describes the board’s connectors. The connectors can be divided into these groups:

Back panel I/O connectors (see page 44)
