Solving
undetermined
problems
If
the
diagnostic
tests
did
not
diagnose
the
failure
or
if
the
server
is
inoperative,
use
the
information
in
this
section.
If
you
suspect
that
a
software
problem
is
causing
failures
(continuous
or
intermittent),
see
Damaged
data
in
CMOS
memory
or
damaged
BIOS
code
can
cause
undetermined
problems.
To
reset
the
CMOS
data,
use
the
clear
CMOS
switch
to
clear
the
CMOS
memory;
see
If
you
suspect
that
the
BIOS
code
is
damaged,
see
Check
the
LEDs
on
all
the
power
supplies.
If
the
LEDs
indicate
that
the
power
supplies
are
working
correctly,
complete
the
following
steps:
1.
Turn
off
the
server.
2.
Make
sure
that
the
server
is
cabled
correctly.
3.
Remove
or
disconnect
the
following
devices,
one
at
a
time,
until
you
find
the
failure.
Turn
on
the
server
and
reconfigure
it
each
time.
v
Any
external
devices.
v
Surge-suppressor
device
(on
the
server).
v
Modem,
printer,
mouse,
and
non-IBM
devices.
v
Each
adapter.
v
Hard
disk
drives.
v
Memory
modules.
The
minimum
configuration
requirement
is
two
512
MB
DIMM
on
the
system
board.
v
Service
processor.
The
following
minimum
configuration
is
required
for
the
server
to
start:
v
One
microprocessor
v
Two
512
MB
DIMM
on
the
system
board
v
One
power
supply
v
Power
cord
v
Power
backplane
v
ServeRAID
SAS
adapter
v
System
board
4.
Turn
on
the
server.
If
the
problem
remains,
suspect
the
following
components
in
the
following
order:
a.
Memory
module
b.
Microprocessor
c.
Power
backplane
d.
System
board
If
the
problem
is
solved
when
you
remove
an
adapter
from
the
server
but
the
problem
recurs
when
you
reinstall
the
same
adapter,
suspect
the
adapter;
if
the
problem
recurs
when
you
replace
the
adapter
with
a
different
one,
suspect
the
system
board.
If
you
suspect
a
networking
problem
and
the
server
passes
all
the
system
tests,
suspect
a
network
cabling
problem
that
is
external
to
the
server.
