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.
Use
an
ESD
wrist
strap
and
the
ESD
connectors
on
the
BladeCenter
T
unit.
Electrostatic
discharge
(ESD)
is
the
release
of
stored
static
electricity
that
can
damage
electric
circuits.
Static
electricity
is
often
stored
in
your
body
and
discharged
when
you
come
in
contact
with
an
object
with
a
different
potential.
The
ESD
wrist
strap
safely
channels
the
electricity
from
your
body
to
a
proper
ground
(the
BladeCenter
T
unit).
Use
an
ESD
wrist
strap
whenever
you
are
working
on
the
BladeCenter
T
unit,
especially
when
you
are
handling
modules,
options,
and
blade
servers.
To
work
properly,
the
wrist
strap
must
have
a
good
contact
at
both
ends
(touching
your
skin
at
one
end
and
connected
to
the
ESD
connector
on
the
front
or
back
of
the
BladeCenter
T
unit.)
