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
subsystem
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
subsystem
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
subsystem
cover
or
any
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather
because
heating
reduces
indoor
humidity
and
increases
static
electricity.
Upgrading
your
RAID
controllers
