The
server
supports
hot-plug,
hot-add,
and
hot-swap
devices
and
is
designed
to
operate
safely
while
it
is
turned
on
and
the
cover
is
removed.
Follow
these
guidelines
when
you
work
inside
a
server
that
is
turned
on:
v
Avoid
wearing
loose-fitting
clothing
on
your
forearms.
Button
long-sleeved
shirts
before
working
inside
the
server;
do
not
wear
cuff
links
while
you
are
working
inside
the
server.
v
Do
not
allow
your
necktie
or
scarf
to
hang
inside
the
server.
v
Remove
jewelry,
such
as
bracelets,
necklaces,
rings,
and
loose-fitting
wrist
watches.
v
Remove
items
from
your
shirt
pocket,
such
as
pens
and
pencils,
that
could
fall
into
the
server
as
you
lean
over
it.
v
Avoid
dropping
any
metallic
objects,
such
as
paper
clips,
hairpins,
and
screws,
into
the
server.
Handling
static-sensitive
devices
Attention:
Static
electricity
can
damage
the
server
and
other
electronic
devices.
To
avoid
damage,
keep
static-sensitive
devices
in
their
static-protective
packages
until
you
are
ready
to
install
them.
To
reduce
the
possibility
of
damage
from
electrostatic
discharge,
observe
the
following
precautions:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
The
use
of
a
grounding
system
is
recommended.
For
example,
wear
an
electrostatic-discharge
wrist
strap,
if
one
is
available.
Always
use
an
electrostatic-discharge
wrist
strap
or
other
grounding
system
when
working
inside
the
server
with
the
power
on
v
Handle
the
device
carefully,
holding
it
by
its
edges
or
its
frame.
v
Do
not
touch
solder
joints,
pins,
or
exposed
circuitry.
v
Do
not
leave
the
device
where
others
can
handle
and
damage
it.
v
While
the
device
is
still
in
its
static-protective
package,
touch
it
to
an
unpainted
metal
surface
on
the
outside
of
the
server
for
at
least
2
seconds.
This
drains
static
electricity
from
the
package
and
from
your
body.
v
Remove
the
device
from
its
package
and
install
it
directly
into
the
server
without
setting
down
the
device.
If
it
is
necessary
to
set
down
the
device,
put
it
back
into
its
static-protective
package.
Do
not
place
the
device
on
the
server
cover
or
on
a
metal
surface.
v
Take
additional
care
when
handling
devices
during
cold
weather.
Heating
reduces
indoor
humidity
and
increases
static
electricity.
Returning
a
device
or
component
If
you
are
instructed
to
return
a
device
or
component,
follow
all
packaging
instructions,
and
use
any
packaging
materials
for
shipping
that
are
supplied
to
you.
Connecting
the
cables
You
must
turn
off
the
server
before
you
connect
any
cables
to
or
disconnect
any
cables
from
the
server.
See
the
documentation
that
comes
with
optional
devices
for
additional
cabling
instructions.
It
might
be
easier
for
you
to
route
cables
before
you
install
certain
devices.
