Installing
a
drive
in
the
rear
hard
disk
drive
cage
The
following
notes
describe
the
types
of
hard
disk
drives
that
the
server
supports
and
other
information
that
you
must
consider
when
you
install
a
hard
disk
drive:
v
The
server
supports
two
25.4
mm
(1-inch),
slim,
3.5-inch
non-hot-swap
hard
disk
drives.
v
The
server
does
not
support
hot-swap
hard
disk
drives.
v
The
server
comes
with
a
front
hard
disk
drive
cage
and
a
rear
hard
disk
drive
cage.
In
the
standard
configuration,
the
server
comes
with
a
hard
disk
drive
in
the
front
drive
cage.
You
can
install
an
additional
hard
disk
drive
in
the
rear
drive
cage.
The
rear
drive
cage
is
adjacent
to
the
power
supply.
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
install
the
drive
in
either
the
front
or
rear
drive
cage
that
comes
with
the
server.
v
The
front
hard
disk
drive
cage
is
under
the
CD
or
DVD
drive
assembly.
Therefore,
you
must
remove
the
CD
or
DVD
drive
assembly
to
access
the
front
hard
disk
drive
cage.
If
you
decide
to
replace
the
hard
disk
drive
in
the
front
drive
cage,
follow
the
instructions
in
“Replacing
the
front
hard
disk
drive”
on
page
36.
v
You
can
install
either
two
SAS
hard
disk
drives
or
two
SATA
hard
disk
drives
in
the
server.
The
server
does
not
support
combining
SAS
and
SATA
drives
in
the
same
configuration.
Operating
the
server
with
an
unsupported
hard
disk
drive
configuration
might
cause
unpredictable
results.
For
a
list
of
supported
drives
for
the
server,
see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
v
If
you
install
only
one
hard
disk
drive,
for
faster
startup,
install
it
in
the
primary
startup
device
location;
that
is,
the
front
drive
cage.
If
you
install
a
second
hard
disk
drive,
install
it
in
the
rear
drive
cage.
v
You
do
not
have
to
set
any
jumpers
or
switches
on
the
hard
disk
drives
before
you
install
the
drives
in
the
server.
Removing
the
rear
hard
disk
drive
cage
assembly
Before
you
can
install
a
hard
disk
drive
in
the
rear
hard
disk
drive
cage
or
remove
a
drive
from
this
drive
cage,
you

cage
