The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable. All of the
connector pin assignments are shown in Appendix C.
Warning! Always completely disconnect the power cord from
your chassis whenever 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.
