Installing
a
hard
disk
drive
The
following
notes
describe
the
types
of
hard
disk
drives
that
your
server
supports
and
other
information
that
you
must
consider
when
installing
a
hard
disk
drive:
v
The
server
supports
two
25.4-mm
(1-inch),
slim,
3.5-inch
hard
disk
drives.
SCSI
server
models
come
with
a
hot-swap
SCSI
backplane.
v
The
SCSI
server
models
support
low
voltage
differential
(LVD)
hot-swap
drives.
Each
hot-swap
drive
is
in
a
tray,
which
has
a
green
activity
LED
and
an
amber
status
LED
in
the
upper-right
corner.
These
LEDs
are
lit
if
the
drive
is
active
and,
in
some
cases,
if
the
drive
fails.
Each
hot-swap
drive
has
a
single-connector-
attached
(SCA)
connector,
which
is
connected
directly
into
the
hot-swap
SCSI
backplane.
The
backplane
is
attached
to
connector
J12
on
the
system
board
and
controls
the
SCSI
IDs
for
the
hot-swap
drives.
Note:
The
drive
in
bay
1
is
assigned
SCSI
ID
0;
the
drive
in
bay
2
is
assigned
SCSI
ID
1.
v
A
non-hot-swap
hard
disk
drive
does
not
require
a
backplane
or
tray
and
it
does
not
have
indicator
LEDs.
However,
you
must
attach
the
blue
rails
that
come
with
the
drive
before
installing
it
in
the
server.
v
A
non-hot-swap
hard
disk
drive
has
a
jumper
block
on
the
rear.
Install
a
jumper
in
the
cable-selection
position
of
the
jumper
block.
For
details,
see
the
notes
under
step
4
on
page
21,
and
the
documentation
that
comes
with
the
drive.
v
If
you
install
only
one
hard
disk
drive,
for
faster
startup,
install
it
in
the
primary
startup
device
bay.
For
hot-swap
SCSI
drives,
the
drive
in
bay
1
is
the
primary
startup
device.
For
SATA
drives,
the
drive
in
bay
2
is
the
primary
startup
device.
v
If
you
are
installing
a
hot-swap
drive,
continue
with
“Installing
a
hot-swap
hard
disk
drive”
on
page
20.
If
you
are
installing
a
non-hot-swap
drive,
go
to
“Installing
a
non-hot-swap
hard
disk
drive”
on
page
21.
