WARNINGS
The procedures in this chapter assume familiarity with the general terminology associated with
personal computers and with the safety practices and regulatory compliance required for using
and modifying electronic equipment.
Disconnect the computer from its power source and from any telecommunications links,
networks, or modems before performing any of the procedures described in this chapter.
Failure to disconnect power, telecommunications links, networks, or modems before you open
the computer or perform any procedures can result in personal injury or equipment damage.
Some circuitry on the board can continue to operate even though the front panel power
button is off.
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.
