Step
4
It
is
possible
that
another
installed
adapter
is
causing
the
problem.
Do
the
following:
1.
Remove
all
installed
adapters
except
the
one
the
CD-ROM
drive
is
attached
to
and
the
one
used
for
the
console.
2.
Try
to
boot
the
standalone
diagnostics
again.
3.
If
unable
to
load
standalone
diagnostics,
go
to
“Step
5.”
4.
If
standalone
diagnostics
load,
reinstall
adapters
(and
attached
devices
as
applicable)
one
at
a
time
and
retry
the
boot
operation
until
the
problem
recurs.
Then
replace
the
adapter
or
device
that
caused
the
problem.
(The
primary
I/O
drawer
backplane
can
also
cause
the
device
or
adapter
to
fail.)

Step
5
The
CD-ROM
drive,
SCSI
cable,
SCSI
adapter,
graphics
adapter,
or
the
primary
I/O
drawer
backplane
is
most
likely
defective.
A
TTY
terminal
attached
to
the
serial
port
also
can
be
used
to
determine
if
the
graphics
adapter
is
causing
the
problem.
This
is
done
by
removing
the
graphics
adapter,
attaching
a
TTY
to
the
serial
port,
and
retrying
standalone
diagnostics.
If
the
standalone
diagnostics
load,
replace
the
graphics
adapter.
1.
Replace
the
CD-ROM
drive.
2.
Replace
the
SCSI
cable.
3.
If
the
CD-ROM
drive
is
attached
to
a
SCSI
adapter
rather
than
the
integrated
SCSI
on
the
primary
I/O
drawer
backplane,
replace
the
SCSI
adapter.
4.
Replace
the
primary
I/O
drawer
backplane.
5.
If
you
replaced
the
indicated
FRUs
and
the
problem
is
still
not
corrected,
or
the
above
descriptions
did
not
address
your
particular
situation,
go
to
