12. Connect required cables to the adapter. Route cables so that they do not block the flow of air from the fans. If you are installing an optional SCSI adapter, see "Cabling an optional SCSI adapter" for additional information. 13. If you have other adapters to install or remove, do so now. 14. If you have installed a full-length adapter, rotate the front adapter-support bracket to the closed (locked) position. 15. Reinstall the rear adapter-retention bracket; then, rotate the bracket to the closed (locked) position. Note: If any adapters in the server are large or have heavy cables attached to them, you can remove the rear adapter-retention bracket and secure all of the adapters with expansion-slot screws. The expansion-slot screws are stored on the frame-support bracket. 16. If you have other options to install, do so now; otherwise, replace the frame-support bracket (see "Removing and installing the support bracket" on page 32) and go to "Completing the installation" on page 60. Cabling an optional SCSI adapter If the server model supports internal SCSI hard disk drives, you can install an optional SCSI adapter to control them. With a SCSI adapter installed, you can configure the internal hard disk drives into disk arrays that use higher levels of RAID functionality than the integrated SCSI controller. You can also cable a SCSI adapter to external hard disk drives. See the SCSI adapter option documentation for complete instructions for installing a SCSI adapter and for additional information about SCSI adapters. Notes: 1. This information in this section does not apply to the ServeRAID 6i+ adapter, which uses the integrated SCSI controller with RAID capabilities on the system board. 2. If the server model supports internal SATA hard disk drives, installing an optional SCSI adapter enables you to add external SCSI tape drives to the server. The information in this section does not apply to a SCSI adapter that will be used to add external SCSI tape drives. 3. An optional SCSI adapter or cable option is required to connect external SCSI devices. Complete the following steps to cable an optional SCSI adapter: 1. Install the SCSI adapter (see "Installing an adapter" on page 51). 2. Connect the SCSI signal cable to the adapter and to one or more of the signal-cable connectors on the rear of the SCSI devices. 3. Connect the SCSI-activity-indicator cable to the adapter and to the SCSI LED connector (JSCSI) on the system board (see "System board internal connectors" on page 86). 54 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

Connect
required
cables
to
the
adapter.
Route
cables
so
that
they
do
not
block
the
flow
of
air
from
the
fans.
If
you
are
installing
an
optional
SCSI
adapter,
see
“Cabling
an
optional
SCSI
adapter”
for
additional
information.
13.
If
you
have
other
adapters
to
install
or
remove,
do
so
now.
14.
If
you
have
installed
a
full-length
adapter,
rotate
the
front
adapter-support
bracket
to
the
closed
(locked)
position.
15.
Reinstall
the
rear
adapter-retention
bracket;
then,
rotate
the
bracket
to
the
closed
(locked)
position.
Note:
If
any
adapters
in
the
server
are
large
or
have
heavy
cables
attached
to
them,
you
can
remove
the
rear
adapter-retention
bracket
and
secure
all
of
the
adapters
with
expansion-slot
screws.
The
expansion-slot
screws
are
stored
on
the
frame-support
bracket.
16.
If
you
have
other
options
to
install,
do
so
now;
otherwise,
replace
the
frame-support
bracket
(see
“Removing
and
installing
the
support
bracket”
on
page
32)
and
go
to
“Completing
the
installation”
on

60.
Cabling
an
optional
SCSI
adapter
If
the
server
model
supports
internal
SCSI
hard
disk
drives,
you
can
install
an
optional
SCSI
adapter
to
control
them.
With
a
SCSI
adapter
installed,
you
can
configure
the
internal
hard
disk
drives
into
disk
arrays
that
use
higher
levels
of
RAID
functionality
than
the
integrated
SCSI
controller.
You
can
also
cable
a
SCSI
adapter
to
external
hard
disk
drives.
See
the
SCSI
adapter
option
documentation
for
complete
instructions
for
installing
a
SCSI
adapter
and
for
additional
information
about
SCSI
adapters.
Notes:
1.
This
information
in
this
section
does
not
apply
to
the
ServeRAID
6i+
adapter,
which
uses
the
integrated
SCSI
controller
with
RAID
capabilities
on
the
system
board.
2.
If
the
server
model
supports
internal
SATA
hard
disk
drives,
installing
an
optional
SCSI
adapter
enables
you
to
add
external
SCSI
tape
drives
to
the
server.
The
information
in
this
section
does
not
apply
to
a
SCSI
adapter
that
will
be
used
to
add
external
SCSI
tape
drives.
3.
An
optional
SCSI
adapter
or
cable
option
is
required
to
connect
external
SCSI
devices.
Complete
the
following
steps
to
cable
an
optional
SCSI
adapter:
1.
Install
the
SCSI
adapter
(see
“Installing
an
adapter”
on
page
51).
2.
Connect
the
SCSI
signal
cable
to
the
adapter
and
to
one
or
more
of
the
signal-cable
connectors
on
the
rear
of
the
SCSI
devices.
3.
Connect
the
SCSI-activity-indicator
cable
to
the
adapter
and
to
the
SCSI
LED
connector
(JSCSI)
on
the
system
board
(see
“System
board
internal
connectors”
on
page
86).
