Power and signal cables for internal drives The server uses cables to connect parallel IDE, simple-swap SATA, hot-swap SATA and hot-swap SAS devices to the power supply and to the system board. (See the User's Guide 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 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 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 IDE connector on the system board. The spare connector can be used to connect an additional IDE optical drive or tape drive to the server. The CD or DVD drive is attached to an ATA 100 signal cable. The blue connector is attached to the system board. The connector on the other end is attached to the master IDE device. The middle connector attaches to an optional optical device or tape drive. v Simple-swap SATA: The combination signal/power cable connects to the system board and simple-swap backplate to provide signal and power to the simple-swap SATA drives. Simple-swap SATA models come with one of the combination signal/power cable connected to the system board and the simple-swap SATA backplate. Notes: 1. You can install the optional ServeRAID-8k Controller in the simple-swap SATA models to get RAID level-5 support. If you install the ServeRAID-8k Controller, you will need to switch the hard disk drive signal cable to a different connector on the system board and connect a RAID level-5 Enabler plug to the system board. See the User's Guide for information on how to install and cable ServeRAID-8k Controller in simple-swap SATA models for RAID level-5 support. 2. When you install the optional ServeRAID-8k Controller in the simple-swap SATA models for RAID support, make sure that you remove the dust shield (if one is present) from the signal connector on the system board before installing the signal cable. Carefully grasp the dust shield and pull it out of the signal connector. v You can order an optional IBM ServeRAID-MR10is VAULT SAS/SATA Controller that supports RAID levels 0, 1, 5, 6, 10, 50, and 60. You can install the ServeRAID-MR10is SAS/SATA controller only in server models with eight 3.5 inch hot-swap hard disk drives installed. For instructions on how to install the ServeRAID-MR10is SAS/SATA controller, see the User's Guide. Note: Note: The onboard RAID controller will be disabled by BIOS when the ServeRAID-MR10is SAS/SATA controller is installed in the server. Chapter 2. Installing options 27

Power
and
signal
cables
for
internal
drives
The
server
uses
cables
to
connect
parallel
IDE,
simple-swap
SATA,
hot-swap
SATA
and
hot-swap
SAS
devices
to
the
power
supply
and
to
the
system
board.
(See
the
User’s
Guide
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
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
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
IDE
connector
on
the
system
board.
The
spare
connector
can
be
used
to
connect
an
additional
IDE
optical
drive
or
tape
drive
to
the
server.
The
CD
or
DVD
drive
is
attached
to
an
ATA
100
signal
cable.
The
blue
connector
is
attached
to
the
system
board.
The
connector
on
the
other
end
is
attached
to
the
master
IDE
device.
The
middle
connector
attaches
to
an
optional
optical
device
or
tape
drive.
v
Simple-swap
SATA:
The
combination
signal/power
cable
connects
to
the
system
board
and
simple-swap
backplate
to
provide
signal
and
power
to
the
simple-swap
SATA
drives.
Simple-swap
SATA
models
come
with
one
of
the
combination
signal/power
cable
connected
to
the
system
board
and
the
simple-swap
SATA
backplate.
Notes:
1.
You
can
install
the
optional
ServeRAID-8k
Controller
in
the
simple-swap
SATA
models
to
get
RAID
level-5
support.
If
you
install
the
ServeRAID-8k
Controller,
you
will
need
to
switch
the
hard
disk
drive
signal
cable
to
a
different
connector
on
the
system
board
and
connect
a
RAID
level-5
Enabler
plug
to
the
system
board.
See
the
User's
Guide
for
information
on
how
to
install
and
cable
ServeRAID-8k
Controller
in
simple-swap
SATA
models
for
RAID
level-5
support.
2.
When
you
install
the
optional
ServeRAID-8k
Controller
in
the
simple-swap
SATA
models
for
RAID
support,
make
sure
that
you
remove
the
dust
shield
(if
one
is
present)
from
the
signal
connector
on
the
system
board
before
installing
the
signal
cable.
Carefully
grasp
the
dust
shield
and
pull
it
out
of
the
signal
connector.
v
You
can
order
an
optional
IBM
ServeRAID-MR10is
VAULT
SAS/SATA
Controller
that
supports
RAID
levels
0,
1,
5,
6,
10,
50,
and
60.
You
can
install
the
ServeRAID-MR10is
SAS/SATA
controller
only
in
server
models
with
eight
3.5
inch
hot-swap
hard
disk
drives
installed.
For
instructions
on
how
to
install
the
ServeRAID-MR10is
SAS/SATA
controller,
see
the
User's
Guide
.
Note:
Note:
The
onboard
RAID
controller
will
be
disabled
by
BIOS
when
the
ServeRAID-MR10is
SAS/SATA
controller
is
installed
in
the
server.
