Electrostatic
discharge
To
prevent
damage
to
the
system,
be
aware
of
the
precautions
you
need
to
follow
when
setting
up
the
system
or
handling
parts.
A
discharge
of
static
electricity
from
a
fi
nger
or
other
conductor
may
damage
system
boards
or
other
static-sensitive
devices.
This
type
of
damage
may
reduce
the
life
expectancy
of
the
device.
To
prevent
electrostatic
damage,
observe
the
following
precautions:
•
To
avoid
hand
contact,
transport
and
store
products
in
static-safe
containers.
•
Keep
static-sensitive
parts
in
their
containers
until
they
arrive
at
static-free
workstations.
•
Place
parts
on
a
grounded
surface
before
removing
them
from
their
containers.
•
Avoid
touching
pins,
leads,
or
circuitry.
•
Always
be
properly
grounded
when
touching
a
static-sensitive
component
or
assembly
(see
26).
Grounding
methods
There
are
several
methods
for
grounding.
Use
one
or
more
of
the
following
methods
when
handling
or
installing
static-sensitive
parts:
•
Use
a
wrist
strap
connected
by
a
ground
cord
to
a
grounded
workstation
or
computer
chassis.
Wrist
straps
are
fl
exible
straps
with
a
minimum
of
1
megohm
(±10
percent)
resistance
in
the
ground
cords.
To
provide
proper
ground,
wear
the
strap
snug
against
the
skin.
•
Use
heel
straps,
toe
straps,
or
boot
straps
at
standing
workstations.
Wear
the
straps
on
both
feet
when
standing
on
conductive
fl
oors
or
dissipating
fl
oor
mats.
•
Use
conductive
fi
eld
service
tools.
•
Use
a
portable
fi
eld
service
kit
with
a
folding
static-dissipating
work
mat.
If
you
do
not
have
any
of
the
recommended
equipment
for
proper
grounding,
have
an
HP-authorized
reseller
install
the
part.
NOTE:
For
more
information
on
static
electricity,
or
assistance
with
product
installation,
contact
your
HP-authorized
reseller.
