Strategy
for
replacing
FRUs
Before
replacing
parts
Make
sure
that
all
diskette
fixes
are
installed
before
replacing
any
FRUs
listed
in
this
manual.
Use
the
following
strategy
to
prevent
unnecessary
expense
for
replacing
and
servicing
FRUs:
v
If
you
are
instructed
to
replace
a
FRU
but
the
replacement
does
not
correct
the
problem,
reinstall
the
original
FRU
before
you
continue
.
v
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.
Attention:
The
setup
configuration
on
the
computer
you
are
servicing
may
have
been
customized.
Running
Automatic
Configuration
may
alter
the
settings.
Note
the
current
configuration
settings
(using
the
View
Configuration
option);
then,
when
service
has
been
completed,
verify
that
those
settings
remain
in
effect.
