If
a
serial
console
is
not
connected,
you
can
use
the
Advanced
Management
Module
to
monitor
the
logs
and
display
informational
and
error
messages.
If
the
firmware
encounters
an
error
during
the
startup
process,
a
message
describing
the
error
together
with
an
error
code
is
displayed
on
the
serial
console.
There
are
two
types
of
error,
where
xxx
represents
the
number
of
the
error
code:
Cxxx
This
is
an
internal
checkpoint.
If
the
system
stops
during
the
startup
process
a
checkpoint
may
be
displayed.
Exxx
This
type
of
error
means
that
there
is
a
failure
that
does
not
allow
the
firmware
to
continue
the
startup
process.
Check
the
error
codes
in
the
QS21
Problem
Determination
and
Service
Guide
.
If
these
do
not
help
resolve
the
problem,
contact
a
service
support
representative.
There
are
cases
where
a
message
that
is
informational
only
is
displayed
on
the
serial
console.
Wxxx
This
is
a
warning
message.
The
firmware
allows
the
startup
process
to
continue,
but
indicates
there
maybe
a
problem.
A
warning
message
can
be
combined
with
an
error
message
to
give
more
complete
information
about
an
error.
Descriptions
for
each
of
the
error
codes
are
not
included
in
this
document.
See
the
Problem
Determination
and
Service
Guide
for
your
blade
server
for
further
information.
