f. Press the adapter firmly into the adapter connector. g. Reinstall the PCI-X dividers between the Active PCI-X adapter slots. h. Push down on the blue adapter guide to keep the adapter steady. i. Close the tab; then, push down on the orange adapter retention latch until it clicks into place, securing the adapter. 6. Connect the internal cables to the adapter. 7. If you have other options to install or remove, do so now. 8. Close the server cover; then, go to "Completing the installation" on page 33. Cabling a ServeRAID adapter Some xSeries 445 models come with an optional IBM ServeRAID™ adapter installed to control the internal hot-swap hard disk drives. If you are installing an optional IBM ServeRAID adapter, see the ServeRAID documentation and the cabling information in this section to install the ServeRAID adapter. Servers that do not come with an IBM ServeRAID adapter installed come with two SCSI cables: v One end of the first SCSI cable is attached to the connector on the SCSI backplane, and the other end is attached to the connector for the integrated SCSI controller under fans 3 and 4. v The second SCSI cable is preinstalled along the inside of the server and both ends are loose inside the server. When you install a ServeRAID adapter, you will connect this cable to the adapter and to the SCSI backplane. The following procedure describes the internal cabling for installing a ServeRAID adapter. Important: When installing multiple ServeRAID adapters in a server that has the PCI-X slot enabled for high scan (boot) priority, ensure that the ServeRAID adapter controlling the startup (boot) drive is installed in a PCI slot that is scanned before the PCI slots that contain the other ServeRAID adapters. See "Installing an adapter" on page 26. Complete the following steps to cable the ServeRAID adapter: 1. Read the safety information beginning on page v and "Installation guidelines" on page 7. 2. Turn off the server and disconnect all power cords and external cables; then, open the server cover (see "Opening the cover" on page 9). 3. Remove fans 3 and 4, which are located just behind the PCI-X slots (see the illustration on page 5 for the locations of the fans). 4. Disconnect the short SCSI cable from the SCSI backplane and the integrated SCSI controller on the I/O board; then, store this short cable in a safe place for future use. 5. Install the ServeRAID adapter in a PCI-X slot (see "Installing an adapter" on page 26). Chapter 2. Installing options 29

Cabling
a
ServeRAID
adapter
Some
xSeries
445
models
come
with
an
optional
IBM
ServeRAID
™
adapter
installed
to
control
the
internal
hot-swap
hard
disk
drives.
If
you
are
installing
an
optional
IBM
ServeRAID
adapter,
see
the
ServeRAID
documentation
and
the
cabling
information
in
this
section
to
install
the
ServeRAID
adapter.
Servers
that
do
not
come
with
an
IBM
ServeRAID
adapter
installed
come
with
two
SCSI
cables:
v
One
end
of
the
first
SCSI
cable
is
attached
to
the
connector
on
the
SCSI
backplane,
and
the
other
end
is
attached
to
the
connector
for
the
integrated
SCSI
controller
under
fans
3
and
4.
v
The
second
SCSI
cable
is
preinstalled
along
the
inside
of
the
server
and
both
ends
are
loose
inside
the
server.
When
you
install
a
ServeRAID
adapter,
you
will
connect
this
cable
to
the
adapter
and
to
the
SCSI
backplane.
The
following
procedure
describes
the
internal
cabling
for
installing
a
ServeRAID
adapter.
Important:
When
installing
multiple
ServeRAID
adapters
in
a
server
that
has
the
PCI-X
slot
enabled
for
high
scan
(boot)
priority,
ensure
that
the
ServeRAID
adapter
controlling
the
startup
(boot)
drive
is
installed
in
a
PCI
slot
that
is
scanned
before
the
PCI
slots
that
contain
the
other
ServeRAID
adapters.
See
“Installing
an
adapter”
on
page
26.
Complete
the
following
steps
to
cable
the
ServeRAID
adapter:
1.
Read
the
safety
information
beginning
on
page
v
and
“Installation
guidelines”
on
page
7.
2.
Turn
off
the
server
and
disconnect
all
power
cords
and
external
cables;
then,
open
the
server
cover
(see
“Opening
the
cover”
on
page
9).
3.
Remove
fans
3
and
4,
which
are
located
just
behind
the
PCI-X
slots
(see
the
illustration
on
page
5
for
the
locations
of
the
fans).
4.
Disconnect
the
short
SCSI
cable
from
the
SCSI
backplane
and
the
integrated
SCSI
controller
on
the
I/O
board;
then,
store
this
short
cable
in
a
safe
place
for
future
use.
5.
Install
the
ServeRAID
adapter
in
a
PCI-X
slot
(see
“Installing
an
adapter”
on
page
26).
