Power,
controls,
and
indicators
This
chapter
describes
the
power
features,
how
to
turn
on
and
turn
off
the
blade
server,
and
what
the
controls
and
indicators
mean.
Turning
on
the
blade
server
After
you
connect
the
blade
server
to
power
through
the
BladeCenter
unit,
the
blade
server
can
start
in
any
of
the
following
ways.
Note:
Unless
otherwise
stated,
references
to
the
BladeCenter
unit
also
apply
to
the
BladeCenter
T
unit.
v
You
can
press
the
power-control
button
on
the
front
of
the
blade
server
(behind
the
control
panel
door)
to
start
the
server.
Notes:
1.
After
you
connect
the
power
cords
of
your
BladeCenter
unit
to
the
electrical
outlets,
wait
until
the
power-on
LED
on
the
blade
server
flashes
slowly
before
pressing
the
blade
server
power-control
button.
During
this
time,
the
service
processor
in
the
BladeCenter
management
module
is
initializing;
therefore,
the
power-control
button
on
the
blade
server
does
not
respond.
2.
While
the
blade
server
is
starting
up,
the
power-on
LED
on
the
front
of
the
server
is
lit
steady.
See
“Controls
and
LEDs”
on
page
8
for
the
power-on
LED
states.
v
If
a
power
failure
occurs,
the
BladeCenter
unit
and
then
the
blade
server
can
start
automatically
when
power
is
restored
(if
the
blade
server
is
configured
through
the
BladeCenter
management
module
to
do
so).
v
You
can
turn
on
the
blade
server
remotely
by
means
of
the
service
processor
in
the
BladeCenter
management
module.
