Firmware
Checkpoints
System
firmware
uses
checkpoints
(progress
codes)
in
the
range
of
Exxx
to
EFFF.
These
checkpoints
occur
during
system
startup
and
can
be
useful
in
diagnosing
certain
problems.
Service
processor
checkpoints
are
listed
in
“Service
Processor
Checkpoints”
on
page
138.
Attention:
If
you
replace
FRUs
or
perform
an
action
and
the
problem
is
still
not
corrected,
go
to
“MAP
1540:
Minimum
Configuration”
on
page
110
unless
otherwise
indicated
in
the
tables.
If
you
replace
FRUs
or
perform
an
action
and
the
problem
is
corrected,
go
to

.
Note:
Firmware
can
hang
due
to
multiple
causes.
In
many
cases,
it
can
be
caused
by
the
primary
processor
or
a
memory
problem
in
the
first
64
MB
of
real
memory.
If
a
location
code
is
not
provided
with
the
checkpoint,
the
following
procedure
will
use
the
primary
processor
and
low
memory
as
the
probable
FRUs.
1.
If
firmware
is
hung
(E100
through
EFFF)
and
a
location
code
is
displayed
on
the
second
line
of
the
operator
panel,
use
that
location
code
as
the
primary
FRU.
2.
If
no
location
code
is
present
or
if
replacing
the
primary
FRU
indicated
in
the
location
code
did
not
fix
the
problem,
then
perform
the
following
actions:
a.
Power
off
the
system
and
go
to
the
service
processor

when
prompted
for
an
address.
d.
Look
at
the
byte
of
data
at
address
330.
If
the
value
is
FF,
go
to
note
3.
If
the
value
is
00-0F,
replace
the
processor
card,
location:
U1.1-P1-C1.
Attempt
to
reboot
the
system.
If
the
system
hangs
at
the
same
checkpoint,
go
to
3.
If
the
system
hangs
at
a
new
checkpoint,
perform
the
actions
associated
with
the
new
checkpoint.
3.
Power
off
the
system.
From
the
service
processor
main
menu,
select
option

then
option

Menu
.
Identify
the
first
configured
memory
riser
card
and
octal
of
DIMMs.
Replace
the
first
octal
of
DIMMs.
4.
If
replacing
the
first
octal
of
configured
DIMMs
does
not
fix
the
problem,
replace
the
memory
riser
card.
If
the
problem
is
still
not
fixed,
