Notes: 1. This cabling example does not apply to the ServeRAID-5i controller, which uses the integrated SCSI controller with RAID capabilities on the system board. 2. An optional ServeRAID-5i controller can be installed only in PCI-X slot 4. Slot 4 is the only PCI-X slot that supports the ServeRAID-5i controller requirements. 3. Connections made to external SCSI devices will be asynchronous. If you are connecting the adapter to any internal SCSI backplane or device, you will need to purchase additional SCSI cables. Contact your IBM marketing representative or reseller for additional information about the number and types of cables that your server configuration requires. Your server comes with one SCSI cable that can only be used with the integrated SCSI controller with RAID capabilities that is on the system board. One end of this SCSI cable is attached to the connector on the SCSI backplane, and the other end is attached to the SCSI channel A connector on the system board. The SCSI channel B connector on the system board is available for use, but the server does not come with a cable attached to it. The following procedure describes the cable routing that is necessary when you install a ServeRAID controller other than ServeRAID-5i. Notes: 1. See the documentation that comes with your adapter for any cabling instructions. 2. Cable identifiers are printed on the cables that come with your server and options. Use these identifiers to connect the cables to the correct connectors. For example, the hard disk drive cables are labeled "HDD option." Complete the following steps to cable the ServeRAID controller: 1. Determine the number of SCSI channels that you want to use on the ServeRAID controller. 2. Review the information in "Installation guidelines" on page 45, "Handling static-sensitive devices" on page 46, and "Safety information" on page 169. 3. Turn off the server and disconnect all power cords and external cables ("Turning off the server" on page 9); then, remove the server cover (see "Removing the server left-side cover and bezel (tower model)" on page 55 or "Removing the server top cover and bezel (rack configuration)" on page 57). 4. Lift the adapter-retention clip on top of the adapter-support bracket; then, remove the full-length adapters. 5. Lift and remove the plastic dividers from PCI-X slots 5 and 6 by lifting the ends of the dividers out of the adapter support bracket and tilting the dividers up out of the server. 6. Disconnect internal cables as necessary, remove the air-baffle assembly, and remove the adapter-support bracket from the server. For complete details, see "Removing and installing the adapter-support bracket" on page 58. Note: You must remove the air-baffle assembly whenever you remove the adapter-support bracket. 7. Disconnect the internal SCSI cable from SCSI connector A (J44) or B (J51) on the system board. See "System-board internal cable connectors" on page 49 for the location of the SCSI connectors.

Notes:
1.
This
cabling
example
does
not
apply
to
the
ServeRAID-5i
controller,
which
uses
the
integrated
SCSI
controller
with
RAID
capabilities
on
the
system
board.
2.
An
optional
ServeRAID-5i
controller
can
be
installed
only
in
PCI-X
slot
4.
Slot
4
is
the
only
PCI-X
slot
that
supports
the
ServeRAID-5i
controller
requirements.
3.
Connections
made
to
external
SCSI
devices
will
be
asynchronous.
If
you
are
connecting
the
adapter
to
any
internal
SCSI
backplane
or
device,
you
will
need
to
purchase
additional
SCSI
cables.
Contact
your
IBM
marketing
representative
or
reseller
for
additional
information
about
the
number
and
types
of
cables
that
your
server
configuration
requires.
Your
server
comes
with
one
SCSI
cable
that
can
only
be
used
with
the
integrated
SCSI
controller
with
RAID
capabilities
that
is
on
the
system
board.
One
end
of
this
SCSI
cable
is
attached
to
the
connector
on
the
SCSI
backplane,
and
the
other
end
is
attached
to
the
SCSI
channel
A
connector
on
the
system
board.
The
SCSI
channel
B
connector
on
the
system
board
is
available
for
use,
but
the
server
does
not
come
with
a
cable
attached
to
it.
The
following
procedure
describes
the
cable
routing
that
is
necessary
when
you
install
a
ServeRAID
controller
other
than
ServeRAID-5i.
Notes:
1.
See
the
documentation
that
comes
with
your
adapter
for
any
cabling
instructions.
2.
Cable
identifiers
are
printed
on
the
cables
that
come
with
your
server
and
options.
Use
these
identifiers
to
connect
the
cables
to
the
correct
connectors.
For
example,
the
hard
disk
drive
cables
are
labeled
“HDD
option.”
Complete
the
following
steps
to
cable
the
ServeRAID
controller:
1.
Determine
the
number
of
SCSI
channels
that
you
want
to
use
on
the
ServeRAID
controller.
2.
Review
the
information
in
“Installation
guidelines”
on
page
45,
“Handling
static-sensitive
devices”
on
page
46,
and
“Safety
information”
on
page
169.
3.
Turn
off
the
server
and
disconnect
all
power
cords
and
external
cables
(“Turning
off
the
server”
on
page
9);
then,
remove
the
server
cover
(see
“Removing
the
server
left-side
cover
and
bezel
(tower
model)”
on
page
55
or
“Removing
the
server
top
cover
and
bezel
(rack
configuration)”
on
page
57).
4.
Lift
the
adapter-retention
clip
on
top
of
the
adapter-support
bracket;
then,
remove
the
full-length
adapters.
5.
Lift
and
remove
the
plastic
dividers
from
PCI-X
slots
5
and
6
by
lifting
the
ends
of
the
dividers
out
of
the
adapter
support
bracket
and
tilting
the
dividers
up
out
of
the
server.
6.
Disconnect
internal
cables
as
necessary,
remove
the
air-baffle
assembly,
and
remove
the
adapter-support
bracket
from
the
server.
For
complete
details,
see
“Removing
and
installing
the
adapter-support
bracket”
on
page
58.
Note:
You
must
remove
the
air-baffle
assembly
whenever
you
remove
the
adapter-support
bracket.
7.
Disconnect
the
internal
SCSI
cable
from
SCSI
connector
A
(J44)
or
B
(J51)
on
the
system
board.
See
“System-board
internal
cable
connectors”
on
page
49
for
the
location
of
the
SCSI
connectors.
