Installing
a
drive
The
following
notes
describe
the
types
of
hard
disk
drives
and
tape
drives
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
drive:
v
The
server
supports
up
to
six
1-inch
(26
mm)
slim-high,
3.5-inch,
hot-swap
hard
disk
drives
without
an
optional
SAS
backplane
installed.
The
server
supports
12
hard
disk
drives
when
an
optional
SAS
backplane
is
installed.
v
For
a
list
of
supported
options
for
the
server,
see
http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
v
The
hot-swap
bays
are
arranged
horizontally
in
the
standard
hard
disk
drive
cage;
the
server
scans
the
hard
disk
drives
and
assigns
drive
IDs
in
the
following
order:
0
through
11.
v
Inspect
the
drive
tray
for
signs
of
damage.
v
Make
sure
that
the
drive
is
correctly
installed
in
the
tray.
v
If
a
RAID
controller
is
installed
in
the
server,
see
the
documentation
that
comes
with
the
controller
for
instructions
for
installing
a
hard
disk
drive.
v
All
hot-swap
drives
in
the
server
should
have
the
same
throughput
speed
rating;
mixing
drives
with
different
speed
ratings
might
cause
all
drives
to
operate
at
the
lower
throughput
speed.
v
To
minimize
the
possibility
of
damage
to
the
hard
disk
drives
when
you
are
installing
the
server
in
a
rack
configuration,
install
the
server
in
the
rack
before
installing
the
hard
disk
drives.
v
You
do
not
have
to
turn
off
the
server
to
install
hot-swap
drives
in
the
hot-swap
drive
bays.
However,
you
must
turn
off
the
server
when
performing
any
steps
that
involve
installing
or
removing
cables.
v
If
the
server
will
be
configured
for
RAID
operation
using
a
ServeRAID
controller,
you
must
configure
the
disk
arrays
before
installing
the
operating
system.
See
the
ServeRAID
documentation
on
the
IBM
ServeRAID
Support
CD
for
additional
information
about
RAID
operation
and
complete
instructions
for
using
ServeRAID
Manager.
v
The
server
supports
up
to
two
5.25-inch,
half-high,
SCSI
tape
drives
or
one
full-high
SCSI
tape
drive
in
the
5.25-inch
bays.
A
SCSI
adapter
is
required
to
support
the
tape
drives.
Install
the
adapter
in
the
first
available
slot
that
is
nearest
the
I/O
board
to
ensure
that
you
can
connect
the
SCSI
cable
to
the
tape
drive.
Route
the
SCSI
cable
along
the
same
path
as
the
existing
media-signal
cable.
Start
at
the
SCSI
adapter
and
route
the
SCSI
cable
over
the
I/O
board
and
through
the
cable
retention
clip;
then,
route
the
cable
through
the
cable
channel
and
through
the
server
to
the
5.25-inch
tape
drive
bays.
To
install
a
full-high
tape
drive,
remove
the
metal
rails
and
screws
from
inside
the
chassis
and
attach
the
rails
to
the
tape
drive
using
the
four
identical
screws.
Fasten
the
drive
in
the
bay
using
the
two
remaining
screws.
To
install
a
half-high
tape
drive,
remove
the
blue
rails
from
the
back
of
the
5.25-inch
filler
panel
and
snap
the
rails
on
the
tape
drive.
The
following
illustration
shows
the
cable
routing
and
the
location
of
the
rails
and
screws
for
installing
a
full-high
tape
drive.
