You
are
here
because
the
diagnostic
tests
did
not
identify
the
failure,
the
Devices
List
is
incorrect,
or
the
system
is
inoperative.
Notes:
1.
If
you

A
damaged
CMOS
can
cause
undetermined
problems.
3.

can
cause
undetermined
problems.
See
“Recovering
SAL/EFI
code”
on
page

Check
the
LEDs
on
all
the
power
supplies
(see
“Power
supply
LED
errors”
on
page
180).
If
the

indicate
the
power
supplies
are
working
correctly,
return
here
and
do
the

reconfigure
each
time).
v
Any
external

v
Top
power
board
v
Processor

Notes:
1.
If
the
problem
goes
away
when
you
remove
an
adapter
from
the
system,
and
replacing
that
adapter
does
not
correct
the
problem,
suspect
the
PCI-X
board.
2.
If
you
suspect
a
networking
problem
and
all
the
system
tests
pass,
suspect
a
network
cabling
problem
external
to
the
system.
