Table 10. IDs of simple-swap drives Drive bay ID 4 0 5 1 6 2 7 3 Power and signal cables for internal drives The server uses cables to connect SATA-attached, simple-swap SATA, hot-swap SAS, and hot-swap SATA devices to the power supply and to the system board. (See "System-board internal connectors" on page 16 for the locations of system-board connectors.) Review the following information before you connect 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 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 ends 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 SATA attached, SATA, SAS, and diskette drives to the system board. Two or three types of signal cables come with the server: - SATA attached (for optical drives): The flat SATA-attached signal cable has two connectors. One of these connectors is attached to the optical drive, and one is attached to one of the connectors on the system board. - (Optional) USB diskette drive: The narrower signal cable has two connectors. One is attached to the diskette drive, and the other is attached to the connector (J11) on the system board. - Simple-swap SATA: Simple-swap SATA models come with four SATA cables that are already connected to the system board and the backplate at the rear of the simple-swap drive cage. - Hot-swap SAS/SATA: Hot-swap SAS/SATA models come with one or two (depending on the model) data cables that connect the SAS/SATA controller to the hot-swap backplane. The data cable provides inherent connectivity for the SAS or SATA drives that the server supports. Therefore, additional cabling is not required for these drives. For more information about the requirements for SAS/SATA cable and connecting SAS/SATA devices, see the documentation that comes with these devices. 40 System x3200 M2 Types 4367 and 4368: User's Guide

Power
and
signal
cables
for
internal
drives
The
server
uses
cables
to
connect
SATA-attached,
simple-swap
SATA,
hot-swap
SAS,
and
hot-swap
SATA
devices
to
the
power
supply
and
to
the
system
board.
(See
“System-board
internal
connectors”
on
page
16
for
the
locations
of
system-board
connectors.)
Review
the
following
information
before
you
connect
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
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
ends
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
SATA
attached,
SATA,
SAS,
and
diskette
drives
to
the
system
board.
Two
or
three
types
of
signal
cables
come
with
the
server:
SATA
attached
(for
optical
drives):
The
flat
SATA-attached
signal
cable
has
two
connectors.
One
of
these
connectors
is
attached
to
the
optical
drive,
and
one
is
attached
to
one
of
the
connectors
on
the
system
board.
(Optional)
USB
diskette
drive:
The
narrower
signal
cable
has
two
connectors.
One
is
attached
to
the
diskette
drive,
and
the
other
is
attached
to
the
connector
(J11)
on
the
system
board.
Simple-swap
SATA:
Simple-swap
SATA
models
come
with
four
SATA
cables
that
are
already
connected
to
the
system
board
and
the
backplate
at
the
rear
of
the
simple-swap
drive
cage.
Hot-swap
SAS/SATA:
Hot-swap
SAS/SATA
models
come
with
one
or
two
(depending
on
the
model)
data
cables
that
connect
the
SAS/SATA
controller
to
the
hot-swap
backplane.
The
data
cable
provides
inherent
connectivity
for
the
SAS
or
SATA
drives
that
the
server
supports.
Therefore,
additional
cabling
is
not
required
for
these
drives.
For
more
information
about
the
requirements
for
SAS/SATA
cable
and
connecting
SAS/SATA
devices,
see
the
documentation
that
comes
with
these
devices.
