Checkout
procedure
The
checkout
procedure
is
the
sequence
of
tasks
that
you
should
follow
to
diagnose
a
problem
in
the
blade
server.
About
the
checkout
procedure
Before
performing
the
checkout
procedure
for
diagnosing
hardware
problems,
review
the
following
information:
v
Read
the
safety
information
that
begins
on
page
vii.
v
The
diagnostic
programs
provide
the
primary
methods
of
testing
the
major
components
of
the
blade
server.
If
you
are
not
sure
whether
a
problem
is
caused
by
the
hardware
or
by
the
software,
you
can
use
the
diagnostic
programs
to
confirm
that
the
hardware
is
working
correctly.
v
When
you
run
the
diagnostic
programs,
a
single
problem
might
cause
more
than
one
error
message.
When
this
happens,
correct
the
cause
of
the
first
error
message.
The
other
error
messages
usually
will
not
occur
the
next
time
you
run
the
diagnostic
programs.
Exception:
If
there
are
multiple
error
codes
or
light
path
diagnostics
LEDs
that
indicate
a
microprocessor
error,
the
error
might
be
in
a
microprocessor
or
in
a
microprocessor
socket.
See
“Microprocessor
problems”
on
page
28
for
information
about
diagnosing
microprocessor
problems.

the
blade
server
is
halted
and
a
POST
error
code
is
displayed,

“POST
error
codes”
on

and
no
error
message
is
displayed,
see
“Troubleshooting
tables”
on
page

and
“Solving
undetermined
problems”
on
page

problems,
check
the
error
log;
see
“Error
logs”
on
page
22
and
“Diagnostic
programs,
messages,
and
error
codes”
on
page
42.
v
If
no
LEDs
are
lit
on
the
blade
server
front
panel,
verify
the
blade
server
status
and
errors
in
the
