If
you
are

Some
computers
have
both
a
processor
board
and
a
system
board.
If
you
are
instructed
to
replace
either
the
processor
board
or
the
system
board,
and
replacing
one
of
them
does
not
correct
the
problem,
reinstall
that
board,
and
then
replace
the
other
one.
v
If
an
adapter
or
a
device
consists
of
more
than
one
FRU,
any
of
the
FRUs
may
be
the
cause
of
the
error.
Before
replacing
the
adapter
or
device,
remove
the
FRUs,
one
by
one,
to
see
if
the
symptoms
change.
Replace
only
the
FRU
that
changed
the
symptoms.

Important
notice
for

Some
components
mounted
on
a
system

cause
a
system
malfunction.

Do
not
drop
a
system
board
or
apply
any
excessive
force
to
it.
v
Avoid
rough
handling
of
any
kind.
v

bending
a
system

How
to
use
error
messages
Use
the
error
codes
displayed
on
the
screen
to
diagnose
failures.
If
more
than
one
error
code
is
displayed,
begin
the
diagnosis
with
the
first
error
code.
Whatever
causes
the
first
error
code
may
also
cause
false
error
codes.
If
no
error
code
is
displayed,
see
whether
the
error
symptom
is
listed
in
the
Symptom-to-FRU
Index
for
the
computer
you
are
servicing.
