Efore You Begin; Removing And Replacing Front-Panel Inserts; Connecting The Drive - Dell 4100 Installation And Troubleshooting Manual

efore You Begin

This chapter describes how to install the following
options:
•
Drives that use the computer's built-in diskette drive
controller.
•
Tape drives that use a controller card
NOTE: If you are installing a SCSI hard-disk drive, see
Chapter 10, "Installing Drives in the Internal Bays."
In order to remove or install drives in the external bays,
you must remove the computer covers and front bezel
according to the instructions in "Removing the Computer
Covers" and "Removing the Front Bezel" in Chapter 7.
To protect the inside of the computer from foreign par-
ticles, a plastic front-panel insert covers each empty
external drive bay. Before you install a drive in an empty
bay, you must first remove the front-panel insert.
Whenever you remove a drive, be sure to replace the
front-panel insert over the empty bay.
Removing and Replacing Front-Panel
Inserts
To remove the front-panel insert for a drive bay you
intend to use, first remove the front bezel as instructed in
"Removing the Front Bezel" in Chapter 7. Then, facing
the inside of the front bezel, press against the center of
the insert with your thumbs until the insert bows suffi-
ciently to loosen the tabs on the sides of the insert (see
Figure 9-2). Pull the insert out of the bezel.
To replace a front-panel insert, position the insert over
the bay opening from the inside of the front bezel and
carefully press the insert into place. A tab on each side of
the insert snaps into a corresponding latch on the inside
of the front bezel.
