v If your operating system supports the Wake on LAN® feature and the blade server power-on LED is flashing slowly, the Wake on LAN feature can turn on the blade server under the following conditions: - The Wake on LAN feature has not been disabled through the management-module Web interface. - The blade server was previously turned on and the operating system was shut down properly. Turning off the blade server When you turn off the blade server, it is still connected to power through the BladeCenter unit. The blade server can respond to requests from the service processor, such as a remote request to turn on the blade server. To remove all power from the blade server, you must remove it from the BladeCenter unit. Shut down your operating system before you turn off the blade server. See your operating system documentation for information about shutting down the operating system. Improper shutdown of a blade server will prevent that blade server from being restarted using Wake on LAN. The blade server can be turned off in any of the following ways: v You can press the power-control button on the blade server (behind the control panel door). This starts an orderly shutdown of the operating system, if this feature is supported by your operating system. Note: After turning off the blade server, wait at least 5 seconds before you press the power-control button to turn on the blade server again. v If the operating system stops functioning, you can press and hold the power-control button for more than 4 seconds to turn off the blade server. v The management module can turn off the blade server. Note: After turning off the blade server, wait at least 30 seconds for the hard disk drives to stop spinning before you remove the blade server from the BladeCenter unit. Chapter 1. Introduction 7

v
If
your
operating
system
supports
the
Wake
on
LAN
®
feature
and
the
blade
server
power-on
LED
is
flashing
slowly,
the
Wake
on
LAN
feature
can
turn
on
the
blade
server
under
the
following
conditions:
–
The
Wake
on
LAN
feature
has
not
been
disabled
through
the
management-module
Web
interface.
–
The
blade

on
and
the
operating
system
was
shut
down
properly.
Turning

the
blade
server
When
you
turn
off
the
blade
server,
it
is
still
connected
to
power
through
the
BladeCenter
unit.
The
blade
server
can
respond
to
requests
from
the
service
processor,
such
as
a
remote
request
to
turn
on
the
blade
server.
To
remove
all
power
from
the
blade
server,
you
must
remove
it
from
the
BladeCenter
unit.
Shut

your
operating
system
before
you
turn
off
the
blade
server.
See
your
operating
system
documentation
for
information
about
shutting
down
the
operating
system.
Improper
shutdown
of
a
blade
server
will
prevent
that
blade
server
from
being
restarted
using
Wake
on
LAN.
The
blade
server
can
be
turned
off
in
any
of
the
following
ways:
v
You
can
press
the
power-control
button
on
the
blade
server
(behind
the
control
panel
door).
This
starts
an
orderly
shutdown
of
the
operating
system,
if
this
feature
is
supported
by
your
operating
system.
Note:
After
turning
off
the
blade
server,
wait
at
least
5
seconds
before
