Symptom
Action
A

1.
Make
sure
that:
v
When
the
blade
server
is
turned
on,
air
is
flowing
from
the
rear
of
the
blade
server
at
the
blower
grille.
If
there
is
no
airflow,
the
blower
is
not
working.
This
causes
the
blade
server
to
overheat
and
shut
down.
v
The
SAS
hard
disk
drives
are
configured
correctly.
2.
Check
the
BMC
log
(see
“Error
