7. Pull the loops of the drive assembly toward each other; then, carefully slide the drive assembly into the drive bay until it stops and release the loops. Note: Do not release the loops on the drive assembly until it is completely seated. 8. Attach the signal cable to the drive: a. Attach one end of the signal cable to the corresponding connector on the rear of the drive. b. Attach the other end of the signal cable to the corresponding connector on the system board. 9. Connect the power cable to the rear of the drive. The connectors are keyed and can be inserted only one way. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 44. Power and signal cables for internal drives The server uses cables to connect parallel IDE, simple-swap SATA, and SAS devices to the power supply and to the system board. (See "System-board internal connectors" on page 14 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 the server 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, make sure that one of the signal cable drive connectors is connected to the drive and that the connector at the other end of the signal cable is connected to the system board or a compatible adapter or controller that you have installed. 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 server 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 When you route a cable, make sure that it does not block the airflow to the rear of the drives or over the microprocessor or DIMMs. 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. Use either a four-wire power cable or SATA power cable with SATA drives, but do not use both at the same time (use one or the other). v Signal cables: Signal cables are typically flat cables, also called ribbon cables, that connect parallel IDE, SATA, SAS, and diskette drives to the system board. Two or three types of signal cables come with the server: - 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 the primary or secondary IDE connector on the system board. The spare connector can be used to connect an additional IDE drive to the server. The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100 signal cables are color-coded. The blue connector is attached to the system board. 36 xSeries 206m Types 8485 and 8490: User's Guide

Power
and
signal
cables
for
internal
drives
The
server
uses
cables
to
connect
parallel
IDE,
simple-swap
SATA,
and
SAS
devices
to
the
power
supply
and
to
the
system
board.
(See
“System-board
internal
connectors”
on
page
14
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
the
server
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,
make
sure
that
one
of
the
signal
cable
drive
connectors
is
connected
to
the
drive
and
that
the
connector
at
the
other
end
of
the
signal
cable
is
connected
to
the
system
board
or
a
compatible
adapter
or
controller
that
you
have
installed.
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
server
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
When
you
route
a
cable,
make
sure
that
it
does
not
block
the
airflow
to
the
rear
of
the
drives
or
over
the
microprocessor
or
DIMMs.
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.
Use
either
a
four-wire
power
cable
or
SATA
power
cable
with
SATA
drives,
but
do
not
use
both
at
the
same
time
(use
one
or
the
other).
v
Signal
cables:
Signal
cables
are
typically
flat
cables,
also
called
ribbon
cables,
that
connect
parallel
IDE,
SATA,
SAS,
and
diskette
drives
to
the
system
board.
Two
or
three
types
of
signal
cables
come
with
the
server:
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
the
primary
or
secondary
IDE
connector
on
the
system
board.
The
spare
connector
can
be
used
to
connect
an
additional
IDE
drive
to
the
server.
The
CD-ROM
drive
is
attached
to
an
ATA
100
signal
cable.
ATA
100
signal
cables
are
color-coded.
The
blue
connector
is
attached
to
the
system
board.
