Drive specifications
The following describes some of the drives you can install in each bay and
their height requirements.
Bay 1: This bay can accommodate a 5.25-inch drive that has a
maximum height of 41.3 mm (1.6 in.). Normally, this bay holds a
factory-installed CD-ROM, DVD-ROM, or CD-RW drive (varies by
model).
Bay 2: This bay can accommodate a 5.25-inch drive such as a
CD-ROM, DVD-ROM, or CD-RW drive. You can also install a 3.5 inch
drive in this bay with a commercially-available 3.5-inch to 5.25-inch
mounting kit. The maximum height for any drive is 41.3 mm (1.6 in.).
Bay 3 This bay contains the factory-installed 3.5-inch diskette drive.
The maximum height for a replacement diskette drive is 25.4 mm (1.0
in.).
Bay 4: This bay contains the factory installed 3.5-inch hard disk drive.
The maximum height for a replacement 3.5-inch hard disk drive is 25.4
mm (1.0 in.).
Power and signal cables for internal drives
Cables connect drives to the power supply and system board. The following
cables are provided:
Ÿ
Four-wire
power cables connect most drives to the power supply. At the
end of these cables are plastic connectors that attach to different drives;
these connectors vary in size. Also, certain power cables attach to the
system board.
Ÿ
Flat
signal cables, also called ribbon cables, connect the drives to EIDE
and diskette drive connectors on the system board (see “Identifying
parts on the system board” on page 65 for the location of these
connectors). There are three drive signal cables in your computer:
– Primary IDE cable: This cable connects the factory-installed hard
disk drive to the Primary EIDE connector on the system board.
This cable supports one drive only.
– Secondary IDE cable: This cable connects the factory-installed
CD-ROM, DVD-ROM, or CD-RW drive in bay 1 to the secondary
EIDE connector on the system board. If a factory-installed drive is
in bay 2, this cable supports that drive also. If there is not a
factory-installed drive in bay 2, there is a spare connector on the
cable that you can use, if you are installing an IDE drive in bay 2.
– Diskette drive cable: This cable connects the factory-installed
diskette drive to the diskette drive connector on the system board.
