Safety Precautions
Dell Compellent
33
Do
not
work
alone
when
working
with
high
‐
voltage
components.
Do
not
use
mats
designed
to
decrease
electrostatic
discharge
as
protection
from
electrical
shock.
Instead,
use
rubber
mats
that
have
been
specifically
designed
as
electrical
insulators.
Do
not
remove
covers
from
the
Power
Control
Module
(PCM).
Disconnect
the
power
connection
before
removing
a
PCM
from
the
enclosure.
Do
not
remove
a
faulty
PCM
unless
you
have
a
replacement
model
of
the
correct
type
ready
for
insertion.
A
faulty
PCM
must
be
replaced
with
a
fully
operational
module
within
24
hours.
Permanently
unplug
the
enclosure
before
you
move
it
or
if
you
think
it
has
become
damaged
in
any
way.
When
powered
by
multiple
AC
sources,
disconnect
all
supply
power
for
complete
isolation.
General Safety Precautions
To
avoid
injury
and
damage
to
the
equipment,
always
follow
general
safety
precautions.
Keep
the
area
around
the
chassis
clean
and
free
of
clutter.
Place
the
chassis
cover
and
any
system
components
that
have
been
removed
away
from
the
controller
or
on
a
table
so
that
they
are
not
in
the
way
of
foot
traffic.
While
working
on
the
controller,
do
not
wear
loose
clothing
such
as
neckties
and
unbuttoned
shirt
sleeves,
which
can
come
into
contact
with
electrical
circuits
or
be
pulled
into
a
cooling
fan.
Remove
any
jewelry
or
metal
objects
from
your
body
because
they
are
excellent
metal
conductors
that
can
create
short
circuits
and
harm
you
if
they
come
into
contact
with
printed
circuit
boards
or
areas
where
power
is
present.
Do
not
lift
an
enclosure
by
the
handles
of
the
Power
Cooling
Modules
(PCMs).
They
are
not
designed
to
hold
the
weight
of
the
entire
enclosure,
and
the
enclosure
cover
may
become
bent.
Before
moving
an
enclosure,
remove
the
PCMs
to
minimize
weight.
In
order
to
comply
with
applicable
safety,
emission,
and
thermal
requirements,
do
not
remove
bay
covers
from
enclosures.
Make
sure
that
all
bays
are
populated
with
plug
‐
in
modules.
Do
not
remove
bay
covers
or
drives
until
ready
to
replace
them.
Warning:
Disconnect
power
from
the
controller
when
removing
or
installing
components
that
are
not
hot
‐
swappable.
When
disconnecting
power,
first
power
down
the
controller
using
the
Storage
Center
System
Manager
and
then
unplug
the
power
cords
from
all
the
power
supply
modules
in
the
controller.
Warning:
To
avoid
injury,
do
not
attempt
to
the
lift
a
controller
or
enclosure
by
yourself.
Always
get
assistance
when
lifting
the
controller.
Caution:
Do
not
operate
the
controller
without
the
cover,
except
when
replacing
cooling
fans.
Warning:
The
memory
modules
may
be
hot
for
several
minutes
after
the
controller
has
been
powered
down.
Wait
for
the
memory
modules
to
cool
before
handling
them.
