Check
the
LEDs
on
all
the
power
supplies
of
the
BladeCenter
unit
in
which
the
blade
server
is
installed.
If
the
LEDs
indicate
that
the
power
supplies
are
working
correctly
and
reseating
the
blade
server
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
server
from
the
management-module
(see
the
BladeCenter
documentation
for
more
information).
3.
Turn
off
the
blade
server.
4.
Remove
the
blade
server
from
the
BladeCenter
unit
and
remove
the
cover.
5.
Make
sure
that
the
blade
server
is
cabled
correctly.
6.
Remove
or
disconnect
the
following
devices,
one
at
a
time,
until
you
find
the
failure.
Reinstall,
turn
on,
and
reconfigure
the
blade
server
each
time.
v
I/O-expansion
card.
v
Drives.
v
Memory
modules.
The
minimum
configuration
requirement
is
1
GB
(two
512
MB
DIMMs).
The
following
minimum
configuration
is
required
for
the
blade
server
to
start:
v
System
board
v
One
microprocessor
v
Two
512
MB
DIMMs
v
A
functioning
BladeCenter
unit
7.
Install
and
turn
on
the
blade
server.
If
the
problem
remains,
suspect
the
following
components
in
the
following
order:
a.
DIMM
b.
System
board
c.
Microprocessor
If
the
problem
is
solved
when
you
remove
an
I/O-expansion
card
from
the
blade
server
but
the
problem
recurs
when
you
reinstall
the
same
adapter,
suspect
the
I/O-expansion
card;
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
blade
server
passes
all
the
system
tests,
suspect
a
network
cabling
problem
that
is
external
to
the
system.

the
blade
server
fail

codes?
–
What
occurs?
When?
Where?
