Diagnostic
programs,
messages,
and
error
codes
The
diagnostic
programs
are
the
primary
method
of
testing
the
major
components
of
the
blade
server.
As
you
run
the
diagnostic
programs,
text
messages
and
error
codes
are
displayed
on
the
screen
and
are
saved
in
the
test
log.
A
diagnostic
text
message
or
error
code
indicates
that
a
problem
has
been
detected;
to
determine
what
action
you
should
take
as
a
result
of
a
message
or
error
code,
see
the
table
in
“Diagnostic
error
codes”
on
page
43.
Running
the
diagnostic
programs

run
the
diagnostic
programs,
complete
the
following
steps:
1.
If
the
blade
server
is
running,
turn
off
the
blade
server.
2.

on
the
blade
server.
3.
When
the

F2
for

appears,

in
“Diagnostic

on
page
43.
If
the
diagnostic
programs
do
not
detect
any
hardware
errors
but
the
problem
remains
during
normal
server
operations,
a
software
error
might
be
the
cause.
If
you
suspect
a
software
problem,
see
the
information
that
comes
with
your
software.
