Installing
and
replacing
devices
This
chapter
contains
information
about
installing
and
replacing
devices.
Working
with
hot-swap
hard
disk
drives
This
section
explains
how
you
can
increase
the
storage
expansion
enclosure
capacity
by
adding
more
hard
disk
drives
or
replacing
existing
drives
with
ones
containing
a
larger
capacity.
Before
you
begin:
v
Read
the
safety
and
handling
guidelines
provided
in
and
in
v
Ensure
that
your
current
system
configuration
is
working
properly.
v
Back
up
all
important
data
before
you
make
changes
to
data
storage
devices.
Before
you
install
or
remove
drive
CRUs,
review
the
following
information:
v
Blank
trays:
An
storage
expansion
enclosure
without
a
full
set
of
drives
(14)
contains
blank
trays
in
the
unused
drive
bays.
Before
installing
new
drives,
you
must
remove
these
empty
trays.
Save
the
empty
trays
for
future
use.
Each
of
the
14
bays
must
always
contain
either
a
blank
tray
or
a
hot-swap
hard
disk
drive.
v
Drive
CRUs:
Your
storage
expansion
enclosure
supports
IBM
2
Gb/s
fibre
channel
hard
disk
drives.
v
Drive
CRU
labels:
A
label
is
provided
on
the
front
of
each
hard
disk
drive.
Use
this
label
to
record
the
location
information
for
each
drive
before
you
remove
it.
Ensure
that
you
keep
track
of
the
drives
and
their
corresponding
bays.
Also,
record
the
location
information
in
(If
you
install
a
drive
in
the
wrong
bay,
you
might
lose
data.)
v
Drive
LEDs:
Each
drive
tray
has
two
LEDs,
which
indicate
the
status
for
that
drive.
See
for
the
drive
LED
states
and
descriptions.

v
Fibre
channel
loop
IDs:
When
you
install
a
hard
disk
drive
in
the
storage
expansion
enclosure,
the
drive
tray
connects
into
a
printed
circuit
board
called
the
midplane
.
The
midplane
sets
the
fibre
channel
loop
ID
automatically,
based
on
the
setting
of
the
enclosure
ID
switch
and
the
physical
location
(bay)
of
the
drive
CRU.
v
Hot-swap
hardware:
Your
storage
expansion
enclosure
contains
hardware
that
enables
you
to
replace
a
failed
hard
disk
drive
without
turning
off
the
storage
expansion
enclosure.
You
can
continue
to
operate
your
system
while
a
hard
disk
drive
is
removed
or
installed.
These
drives
are
known
as
hot-swap
hard
disk
drives.
