The following sections tell how to make each connection. In most cases, you will sim-

ply need to connect a standard cable. All of the connector pin assignments are

shown in Appendix A.

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.
