Notes:
1.
Be
sure
to
unplug
the
power
cords
before
removing
or
installing
processor
cards
or
the
system
backplane
to
avoid
damage
to
it.
2.
This
MAP
assumes
that
a
CD-ROM
drive
is
installed
and
connected
to
the
integrated
EIDE
adapter,
and
a
diagnostic
CD-ROM
disc
is
available.
3.
If
a
power-on
password
or
privileged-access
password
is
set,
you
are
prompted
to
enter
the
password
before
the
diagnostic
CD-ROM
can
load.
4.
The
term
POST
indicators
refers
to
the
device
mnemonics
that
appear
during
the
power-on
self-test
(POST).
5.
The
service
processor
might
have
recorded
one
or
more
symptoms
in
its
error
log.
v
If
you
arrived
here
after
performing
a
slow
boot,
look
for
a
possible
new
error
that
occurred
during
the
slow
boot.
If
there
is
a
new
error,
and
its
actions
call
for
a
FRU
replacement,
perform
those
actions.
If
this
does
not
resolve
the
problem,
go
to
“Step
1548-1”
on
page
114.
v
If
an
additional
slow
boot
has
not
been
performed,
or
if
the
slow
boot
did
not
yield
a
new
error
code,
look
at
the
error
that
occurred
just
before
the
original
error.
Perform
the
actions
associated
with
that
error.
If
the
problem
is
not
resolved,
go
to“Step
1548-1”
on
page
114.
v
If
a
slow
boot
results
in
the
same
error
code,
and
there
are
no
error
codes
before
the
original
error
code,
go
to
“Step
1548-1”
on
page
114.
It
is
a
good
idea
to
examine
that
error
log
before
proceeding
(see
“System
Information
Menu”
on
page
238).
6.
The
service
processor
might
have
been
set
by
the
user
to
monitor
system
operations
and
to
attempt
recoveries.
You
might
want
to
disable
these
actions
while
you
diagnose
and
service
the
system.
If
you
disable
them,
make
notes
of
their
current
settings
so
that
you
can
restore
them
before
you
leave.
The
following
settings
may
be
of
interest
to
you.

Setup
Menu,
go
to
the
Serial
Port
Selection
Menu
and
disable
call-out
on
both
serial
ports.

that
the
system
has
not
been
set
to
boot
to
the
SMS
menus
or
to
the
open
firmware
prompt.
From
the
System
Power
Control
Menu,
select

Purpose
of
this
MAP
This
MAP
is
used
to
locate
defective
FRUs
not
found
by
normal
diagnostics.
For
this
procedure,
diagnostics
are
run
on
a
minimally
configured
system.
If
a
failure
is
detected
on
the
minimally
configured
system,
the
remaining
FRUs
are
exchanged
one
at
a
time
until
the
failing
FRU
is
identified.
If
a
failure
is
not
detected,
FRUs
are
added
back
until
the
failure
occurs.
The
failure
is
then
isolated
to
the
failing
FRU.
