Power and Signal Cables
Your computer uses cables to connect the power supply to the riser card and to
integrated drive electronics (IDE) drives. The diskette drive is also powered
through a cable attached to the riser card. The following cables are provided:
Four-wire power cables connect most drives to the power supply. At the ends of
these cables are plastic connectors that attach to different drives; these
connectors vary in size. Also, some power cables attach to the riser card.
Flat signal cables, sometimes called ribbon cables, connect IDE drives to the riser
card. There are two sizes of signal cables that come with your computer:
– The wider signal cable attaches to the installed hard disk drive and to the
primary IDE connector on the back of the riser card.
– The narrower signal cable attaches to the diskette drive and to the diskette
drive connector on the back of the riser card.
The following illustration shows the connectors on the riser card.
