12.
Attach
the
new
drive
to
the
drive
tray.
Place
the
drive
on
the
drive
tray
and
align
the
holes
on
the
drive
with
the
mounting
pins
on
the
drive
tray.
Gently
pull
both
sides
of
the
drive
tray
outward
and
insert
the
mounting
pins
into
the
holes
on
the
drive.
13.
Slide
the
drive
into
the
drive
bay
until
the
drive
snaps
into
place.
14.
Determine
whether
the
drive
is
a
Serial
ATA
or
SCSI
device;
then,
connect
one
end
of
the
applicable
signal
cable
into
the
back
of
the
drive
and
the
other
end
of
this
cable
into
the
applicable
Serial
ATA
or
SCSI
connector
on
the
system
board.
If
there
are
open
connectors
on
the
cables
connecting
existing
Serial
ATA
or
SCSI
drives,
you
can
use
these
cables
to
connect
the
new
drive.
See
“Power
and
signal
cables
for
internal
drives”
for
additional
information
about
cabling
drives
and
“System-board
internal
connectors”
on
page
36
for
the
location
of
Serial
ATA
and
SCSI
connectors
on
the
system
board.
15.
Route
the
signal
cable
so
that
it
does
not
block
the
airflow
to
the
rear
of
the
drives
or
over
any
microprocessor.
16.
Connect
the
power
cable
to
the
back
of
the
drive.
The
connectors
are
keyed
and
can
be
inserted
only
one
way.
17.
Push
the
drive
cage
outward,
and
press
in
on
the
drive-cage
release
tab.
Rotate
the
cage
part-way
into
the
computer;
then,
reconnect
any
power
cables
you
disconnected
in
step
8
and
rotate
the
cage
the
rest
of
the
way
back
into
the
computer.
Make
sure
that
the
drives
and
cables
do
not
strike
the
microprocessor
fan
sink.
18.
If
you
have
other
options
to
install
or
remove,
do
so
now.
19.
Replace
the
support
bracket
(see
“Removing
and
installing
the
support
bracket”
on
page
38).
20.
Replace
the
side
cover
(see
“Replacing
the
side
cover”
on
page
63).
21.
Reconnect
the
external
cables
and
power
cords;
then,
turn
on
the
attached
devices
and
the
computer.
Power
and
signal
cables
for
internal
drives
Your
computer
uses
cables
to
connect
IDE,
Serial
ATA,
and
SCSI
devices
to
the
power
supply
and
to
the
system
board.
(See
“System-board
internal
connectors”
on
page
36
for
the
location
of
system-board
connectors.)
Review
the
following
information
before
connecting
power
and
signal
cables
to
internal
drives:
v
The
drives
that
are
preinstalled
in
your
computer
come
with
power
and
signal
cables
attached.
If
you
replace
any
drives,
remember
which
cable
is
attached
to
which
drive,
or
label
the
cables.
v
When
you
install
a
drive,
make
sure
that
one
of
the
drive
connectors
of
the
signal
cable
is
connected
to
the
drive
and
that
the
connector
at
the
other
end
of
the
signal
cable
is
connected
to
the
system
board.
v
When
you
install
a
drive,
set
the
jumpers
either
to
disable
auto-start
or
to
delay
startup,
to
prevent
the
system
power
supply
from
being
overtaxed
by
all
drives
trying
to
spin
up
at
once.
v
The
computer
has
two
IDE
buses,
primary
and
secondary.
Each
of
these
buses
supports
up
to
two
IDE
devices.
The
primary
IDE
bus
uses
connector
IDE1
on
the
system
board
and
the
secondary
IDE
bus
uses
connector
IDE2.
v
If
you
have
only
one
IDE
device
on
a
cable,
it
must
be
set
as
a
master
device.
v
If
two
IDE
devices
are
used
on
a
single
cable,
one
must
be
designated
as
the
master
device
and
the
other
as
the
subordinate
device;
otherwise,
the
computer
might
not
recognize
some
of
the
IDE
devices.
The
master
and
subordinate
designation
is
determined
by
switch
or
jumper
settings
on
each
IDE
device.
