Attention:
Static
electricity
that
is
released
to
internal
server
components
when

of
data.
To
avoid
this
potential
problem,
always
use
an
electrostatic-discharge
wrist
strap
or
other
grounding
system
when
working
inside
the
server
with
the
power
on.

7.
Grasp
the

front.
8.
Lift
the

out
of
the
server,
and
make
sure
that
the

tabs
clear
the
