Installing
and
replacing
components
This
chapter
provides
instructions
to
help
you
install
or
remove
customer
replaceable
units
(CRUs),
such
as
hot-swap
drives,
fans,
RAID
controllers,
and
power
supplies.
This
chapter
also
provides
instructions
to
help
you
add
new
DS4000
EXP100
expansion
units
to
existing
DS4100
configuration.

Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
electronic
devices
and
your
system.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
To
reduce
the
possibility
of
electrostatic
discharge,
observe
the
following
precautions:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
Handle
the
device
carefully,
holding
it
by
its
edges
or
its
frame.
v
Do
not
touch
solder
joints,
pins,
or
exposed
printed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
possibly
damage
the
device.
v
While
the
device
is
still
in
its
static-protective
package,
touch
it
to
an
unpainted
metal
part
of
the
storage
server
for
at
least
two
seconds.
This
drains
static
electricity
from
the
package
and
from
your
body.
v
Remove
the
device
from
its
package
and
install
it
directly
into
your
storage
server
without
setting
it
down.
If
it
is
necessary
to
set
the
device
down,
place
it
in
its
static-protective
package.
Do
not
place
the
device
on
your
storage
server
cover
or
any
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather
because
heating
reduces
indoor
humidity
and
increases
static
electricity.
Working
with
hot-swap
hard
disk
drives
Drives
are
devices
that
the
system
uses
to
store
and
retrieve
data.
This
section
explains
how
you
can
increase
the
storage-server
capacity
by
adding
more
drives
or
replacing
existing
drives
with
ones
containing
a
larger
capacity.
Before
you
begin,
complete
the
following
tasks:
v
Read
the
safety
and
handling
guidelines
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.
Attention:
Never
hot-swap
a
drive
CRU
when
its
green
Activity
LED
is
flashing.
Hot-swap
a
drive
CRU
only
when
its
amber
Fault
LED
is
completely
on
and
not
flashing
or
when
the
drive
is
inactive
with
the
green
Activity
LED
on
and
not
flashing.
