4.6 Installing FDD and Slim CD-ROM Drive
Installation of a floppy disk drive and slim CD-ROM drive is similar to
that for a hard disk drive. The metal plate for holding the FDD and the
CD-ROM support bracket are on the left side of the shielding case. The
26-pin and 40-pin yellow FPC cables are for connecting the FDD and
CD-ROM respectively. Only 3.5" floppy disk drives (720 KB and 1.44
MB) and slim CD-ROM drives can be attached to the metal plate and
CD-ROM support bracket.
1.
Detach and remove the plastic rear cover and side panel.
2. There is a metal plate which holds the FDD and slim CD-ROM
drive to the metal shielding case. There is also a slim CD-ROM
support bracket which is attached to the shielding case. There are
two screws ("A") on the metal plate. Unscrew these two screws.
(See Fig. 4-5.)
3. Push the metal plate toward the outside of the unit. This will free it
from the two lugs of the shielding case.
4. Slide the CD-ROM support bracket toward the outside of the panel
PC, and remove it.
5. Place the FDD on the metal plate. There are four small screws, two
on each side of the metal plate. Tighten these screws.
6. Place the support bracket against the slim CD-ROM drive. It should
fit neatly into the space allocated for the bracket. (See Fig. 4-5.)
7. Attach the support bracket to the slim CD-ROM drive by tightening
the two small screws located in the bracket.
8. Insert the FDD assembly into the shielding case. Then insert the
slim CD-ROM drive assembly into the shielding case. Make sure
that the hooked lug on the slim CD-ROM drive assembly engages
into the corresponding slot of the combined FDD assembly and
shielding case.
9. Connect the FDD cable (26-pin to 26-pin) and CD-ROM cable (40-
pin to 40-pin). The other end of the FDD cable is connected to con-
nector CN10 on the PC board. The other end of the CD-ROM cable
is connected to connector CN18 on the PC board.
10. Slide the FDD assembly and slim CD-ROM assembly toward the
inside of the panel PC, as far as they will go.
11. Secure the two screws ("A") of the metal plate to the shielding case.
