Installing Drives

Y
our Dell computer has five drive bays for installing
the following types of drives:
•
The user-accessible drive cage at the front of the
computer consists of one 3.5-inch bay (dedicated to
a 3.5-inch diskette drive) and two 5.25-inch drive
bays that can hold up to two half-height, 5.25-inch
devices—typically tape drives or CD-ROM drives.
•
The two vertically positioned hard-disk drive bays
can each hold a 3.5-inch enhanced integrated drive
electronics (EIDE) or small computer system inter-
face (SCSI) hard-disk drive. The bay on the right (as
you face the front of the computer) can hold a
1-inch-high (or smaller) drive, whereas the bay on
the left accommodates a 1.6-inch-high (or smaller)
drive.
The next four sections contain information that you will
need in several of the installation procedures described
later in the chapter. The remaining sections of this chap-
ter cover installing each type of drive individually.
NOTE: In all the following procedures, left and right refer
to your left and right as you face the front of the computer (see
Figure 9-1).

onfiguring Your Drive
Because you may need to tailor a drive to work with your
system, certain installation instructions in this chapter
refer you to the documentation that came with the drive
for information on enabling termination or changing
jumpers or switches.
Drives installed by Dell are configured to work with your
system. However, check the documentation that came
with any new drive to verify that the jumpers and
switches are set correctly for your particular configura-
tion, and make any necessary alterations (see "Jumpers"
and "Switches" in Appendix B).
For example, when installing a second drive on an EIDE
channel, you must ensure that it is configured for the
Cable Select jumper setting so that it will operate prop-
erly with the other EIDE drive on the channel.
