CAUTION
Only the back panel USB, front panel USB, VGA, and PS/2 connectors have overcurrent
protection. The Desktop Boards' internal connectors are not overcurrent protected and should
connect only to devices inside the computer's chassis, such as fans and internal peripherals. Do

presented by the external devices could cause damage to the computer, the interconnecting cable,
and the external devices themselves.
