3-14 Option Installation
Diskette Drive Signal Cable
A two-connector diskette drive signal cable comes attached to the system board and to the
standard 1.44-MB diskette drive. If your system comes standard with an Iomega Ditto tape
backup unit, the signal cable has three connectors.
Depending on your system, installation of a tape backup unit may require the replacement
of the existing diskette drive signal cable with a three-connector cable. Connect an optional
tape backup unit to the middle connector on the three-connector diskette drive signal cable.
The colored edge of the cable goes to pin 1 on the cable connector. Align the red edge of
the cable with pin 1 (the notched end) on the drive connector.
Figure 3-10 shows a three-connector diskette drive signal cable.

IDE Signal Cables
Each system comes with a three-connector IDE interface cable attached to the primary IDE
connector and the installed hard disk. A second IDE cable connects to the CD-ROM drive
and to the secondary IDE connector. In some systems, a Zip drive also comes attached to
the primary IDE cable.
Figure 3-11 shows a typical three-connector IDE cable. If the IDE cable is not keyed with a
connector tab, align the colored edge of the cable with the pin 1 side of the drive connector.
