Power
and
signal
cables
for
internal
drives
Your
computer
uses
cables
to
connect
IDE
and
SCSI
devices
to
the
power
supply
and
to
the
system
board.
(See
“System-board
internal
connectors”
on
page
12
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.
v
When
you
install
a
drive,
ensure
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
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.
v
If
two
IDE
devices
are
on
a
single
cable
and
only
one
is
a
hard
disk
drive,
the
hard
disk
drive
must
be
set
as
a
master
device.
The
following
cables
are
provided:
v
Power
cables:
Four-wire
power
cables
connect
the
drives
to
the
power
supply.
At
the
end
of
these
cables
are
plastic
connectors
that
can
be
attached
to
different
drives;
these
connectors
vary
in
size.
v
Signal
cables:
Signal
cables
are
typically
flat
cables,
also
called
ribbon
cables,
that
connect
IDE,
SCSI,
and
diskette
drives
to
the
system
board.
Two
or
three
types
of
signal
cable
come
with
your
computer.
–
IDE:
The
wider
IDE
signal
cable
has
three
connectors.
One
of
these
connectors
is
attached
to
the
drive,
one
is
a
spare,
and
the
third
is
attached
to
