boards,
wear
a
wrist
strap
and
connect
it
to
the
chassis
prior
to
starting
maintenance.
■
If
excessive
force
is
applied
to
the
motherboard
unit,
the
components
mounted
on
the
printed
boards
could
be
damaged.
When
handling
the
motherboard
unit,
observe
the
following
precautions:
■
Handle
the
motherboard
unit
by
holding
it
by
the
handle.
■
When

the
motherboard
unit
from
its
packaging,
keep
the
motherboard
unit
horizontal
until
you
lay
it
on
the
cushioned
ESD
mat.
■
Connectors
and
components
on
the
motherboard
unit
have
thin
pins
that
bend
easily.
Therefore,
do
not
place
the
motherboard
unit
on
a
hard
surface.
■
Be
careful
not
to
damage
the
small
parts

by
incorrect
handling.
Do
not
touch
the
heat
sinks
with
your
hands
or
other
objects
while
replacing
or
removing
motherboard
units.
If
a
heat
sink
becomes
disconnected
or
is
broken,
obtain
a
replacement
motherboard
unit.
When
storing
or
carrying
a
motherboard
unit,
ensure
that
the
heat
sinks
are
sufficiently
protected.
■
When
removing
a
cable
such

latch
lock
of
the
connector,
use
a
flat
headed
screwdriver
to

and
release
the

If
you
use
force
to
remove
the
cable,
the
LAN
port
of
the
motherboard
unit
or
a
PCI
Express
(PCIe)
card
may
be
damaged.
■
Do
not
use
any
power
cords
other

and
there
are
no
other
such
defects.
Do
not
mount
the
