Cabling an optional SCSI adapter You can install an optional SCSI adapter in your server to control the internal hard disk drives. With a SCSI adapter installed, you can configure the internal hard disk drives into disk arrays. You can also cable a SCSI adapter to external hard disk drives. See your SCSI adapter option documentation for complete instructions for installing a SCSI adapter in your server and for additional information about SCSI adapters. Notes: 1. This information in this section does not apply to the ServeRAID-6i controller, which uses the integrated SCSI controller with RAID capabilities on the system board. 2. 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 40). 2. Connect the SCSI signal cable to the adapter and to one or more of the signal-cable connectors to the rear of the SCSI devices. 3. Connect the SCSI-activity-indicator cable to the adapter and to the SCSI-LED connector (J18) on the system board. See "System-board internal connectors" on page 91 for the location of the SCSI-LED connector.

Cabling
an
optional
SCSI
adapter
You
can
install
an
optional
SCSI
adapter
in
your
server
to
control
the

hard
disk
drives.
With
a
SCSI
adapter
installed,
you
can
configure
the
internal
hard
disk
drives
into
disk
arrays.
You
can
also
cable
a
SCSI
adapter
to
external
hard
disk
drives.
See
your
SCSI
adapter
option
documentation
for
complete
instructions
for
installing
a
SCSI
adapter
in
your
server
and
for
additional
information
about
SCSI
adapters.
Notes:
1.
This
information
in
this
section
does
not
apply
to
the
ServeRAID-6i
controller,
which
uses
the
integrated
SCSI
controller
with
RAID
capabilities
on
the
system
board.
2.
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
40).
2.
Connect
the
SCSI
signal
cable
to
the
adapter
and
to
one
or
more
of
the
signal-cable
connectors
to
the
rear
of
the
SCSI
devices.
3.
Connect
the
SCSI-activity-indicator
cable
to
the
adapter
and
to
the
SCSI-LED
connector
(J18)
on
the
system
board.

internal
connectors”
on
page
