The other internal connectors/headers 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/headers 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. NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. This section describes the board's connectors and headers. The connectors and headers can be divided into these groups: • Back panel I/O connectors (see page 44) • Component-side connectors and headers (see page 45) 43

CAUTION
Only the following connectors and headers have overcurrent protection:
Back panel
and front panel USB.
The other internal connectors/headers 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/headers 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.

NOTE
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable.
Use
shielded cable that meets the requirements for full-speed devices.
This section describes the board’s connectors and headers.
The connectors and
headers can be divided into these groups:
•
Back panel I/O connectors (see page 44)
