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.
