Warning! Always completely disconnect the power cord from your chassis when-
ever you are working on it. Do not make connections while the power is
on. Sensitive electronic components can be damaged by a sudden rush
of power. Only experienced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static charge before touching the
CPU card. Modern electronic devices are very sensitive to static electric
charges. Use a grounding wrist strap at all times. Place all electronic
components on a static-dissipative surface or in a static-shielded bag
when they are not in the chassis.
