Electrostatic
discharge
(ESD)
and
ESD
protection:
ESD
can
damage
drives,
boards,
and
other
parts.
We
recommend
that
you
perform
all
procedures
in
this
chapter
only
at
an
ESD
workstation.
If
one
is
not
available,
provide
some
ESD
protection
by
wearing
an
antistatic
wrist
strap
attached
to
chassis
ground
any
unpainted
metal
surface
on
the
server
when
handling
parts.
ESD
and
handling
boards:
Always
handle
boards
carefully.
They
can
be
extremely
sensitive
to
electrostatic
discharge
(ESD).
Hold
boards
only
by
their
edges.
After
removing
a
board
from
its
protective
wrapper
or
from
the
server,
place
the
board
component
side
up
on
a
grounded,
static
free
surface.
Use
a
conductive
foam
pad
if
available
but
not
the
board
wrapper.
Do
not
slide
board
over
any
surface.
Installing
or
removing
jumpers:
A
jumper
is
a
small
plastic
encased
conductor
that
slips
over
two
jumper
pins.
Some
jumpers
have
a
small
tab
on
top
that
can
be
gripped
with
fingertips
or
with
a
pair
of
fine
needle
nosed
pliers.
If
the
jumpers
do
not
have
such
a
tab,
take
care
when
using
needle
nosed
pliers
to
remove
or
install
a
jumper;
grip
the
narrow
sides
of
the
jumper
with
the
pliers,
never
the
wide
sides.
Gripping
the
wide
sides
can
damage
the
contacts
inside
the
jumper,
causing
intermittent
problems
with
the
function
controlled
by
that
jumper.
Take
care
to
grip
with,
but
not
squeeze,
the
pliers
or
other
tool
used
to
remove
a
jumper,
or
the
pins
on
the
board
may
bend
or
break.
