If
the
diagnostic
tests
did
not
diagnose
the
failure
or
if
the
blade
workstation
is
inoperative,
use
the
information
in
this
section.
If
you
suspect
that
a
software
problem
is
causing
failures
(continuous
or
intermittent),
see
“Software
problems”
on
page
68.
Damaged
data
in
CMOS
memory
or
damaged
BIOS
code
can
cause
undetermined
problems.
To
reset
the
CMOS
data,
remove
and
replace
the
battery
to
override
the
power-on
password
and
clear
the
CMOS
memory;
see
“Removing
the
battery”
on
page
30.
If
you
suspect
that
the
BIOS
code
is
damaged,
see
“Recovering
from
a
BIOS
update
failure”
on
page
74.
Check
the
LEDs
on
all
the
power
supplies
of
the
BladeCenter
unit
in
which
the
blade
workstation
is
installed.
If
the
LEDs
indicate
that
the
power
supplies
are
working
correctly
and
reseating
the
blade
workstation
does
not
correct
the
problem,
complete
the
following
steps:
1.
Make
sure
that
the
control
panel
connector
is
correctly
seated
on
the
system
board
(see
“System
board
connectors”
on
page
7
for
the
location
of
the
connector).
2.
If
no
LEDs
on
the
control
panel
are
working,
replace
the
bezel
assembly;
then,
try
to
turn
on
the
blade
workstation
from
the
management
module
(see
the
documentation
for
the
BladeCenter
unit
and
management
module
for
more
information).
3.
Turn
off
the
blade
workstation.
4.
Remove
the
blade
workstation
from
the
BladeCenter
unit
and
remove
the
cover.
5.
Remove
or
disconnect
the
following
devices,
one
at
a
time,
until
you
find
the
failure.
Reinstall,
turn
on,
and
reconfigure
the
blade
workstation
each
time.
v
I/O-expansion
card
v
Hard
disk
drives
v
Memory
modules.
The
minimum
configuration
requirement
is
1
GB
(two
512
MB
DIMMs
on
the
system
board).
The
following
minimum
configuration
is
required
for
the
blade
workstation
to
start:
v
System
board
v
Microprocessor
v
Two
512
MB
DIMMs
v
A
functioning
BladeCenter
unit
6.
Install
and
turn
on
the
blade
workstation.
If
the
problem
remains,
suspect
the
following
components
in
the
following
order:
a.
DIMM
b.
Microprocessor
c.
System
board
If
the
problem
is
solved
when
you
remove
an
I/O-expansion
card
from
the
blade
workstation
but
the
problem
recurs
when
you
reinstall
the
same
card,
suspect
the
I/O-expansion
card;
if
the
problem
recurs
when
you
replace
the
card
with
a
different
one,
suspect
the
system
board.
If
you
suspect
a
networking
problem
and
the
blade
workstation
passes
all
the
system
tests,
suspect
a
network
cabling
problem
that
is
external
to
the
system.
