Removing the blade server from the BladeCenter unit The following illustration shows an example of how to remove the blade server from a typical BladeCenter unit; the orientation of the blade server depends on the type of BladeCenter unit you have. Note: The illustrations in this document might differ slightly from your hardware. Attention: v To maintain proper system cooling, do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blade installed in each blade bay. v Note the number of the bay that contains the blade server that you will remove. You will need this information if you decide to reinstall the blade server in the BladeCenter unit. If you reinstall the blade server, be sure to reinstall it in the same bay from which it was removed. Reinstalling a blade server into a different bay than the one from which it was removed could have unintended consequences, such as incorrectly reconfiguring the blade server. Some blade server configuration information and update options are established according to bay number. If you reinstall the blade server into a different bay, you might have to reconfigure the blade server. Note: The blade server is a hot-swap device, and the blade bays in the BladeCenter unit are hot-swap bays. Therefore, you can install or remove the blade server without removing power from the BladeCenter unit. However, you must turn off the blade server before removing it from the BladeCenter unit. Complete the following steps to remove the blade server: 1. Read the safety information beginning on page iii and "Installation guidelines" on page 71 2. If the blade server is operating, the power-on LED is lit continuously (steady). Shut down the operating system by typing the shutdown -h now command. Refer to your operating system documentation. If the blade server was not turned off, press the power-control button (behind the blade-server control-panel door) to turn off the blade server. See "Blade server controls and LEDs" on page 14 for more information about the location of the power-control button. Attention: Wait at least 30 seconds for the hard disk drives to stop spinning, before proceeding to the next step. 3. Open the two release levers as shown in the illustration. The blade server moves out of the bay approximately 0.6 cm (0.25 inch). 4. Pull the blade server out of the bay. 5. Place either a filler blade or a new blade server in the bay within 1 minute.

Removing
the
blade
server
from
the
BladeCenter
unit
The
following
illustration
shows
an
example
of
how
to
remove
the
blade
server
from
a
typical
BladeCenter
unit;
the
orientation
of
the
blade
server
depends
on
the
type
of
BladeCenter
unit
you
have.
Note:
The
illustrations
in
this
document
might
differ
slightly
from
your
hardware.
Attention:
v
To
maintain
proper
system
cooling,
do
not
operate
the
BladeCenter
unit
for
more
than
1
minute
without
a
blade
server
or
filler
blade
installed
in
each
blade
bay.
v
Note
the
number
of
the
bay
that
contains
the
blade
server
that
you
will
remove.
You
will
need
this
information
if
you
decide
to
reinstall
the
blade
server
in
the
BladeCenter
unit.
If
you
reinstall
the
blade
server,
be
sure
to
reinstall
it
in
the
same
bay
from
which
it
was
removed.
Reinstalling
a
blade
server
into
a
different
bay
than
the
one
from
which
it
was
removed
could
have
unintended
consequences,
such
as
incorrectly
reconfiguring
the
blade
server.
Some
blade
server
configuration
information
and
update
options
are
established
according
to
bay
number.
If
you
reinstall
the
blade
server
into
a
different
bay,
you
might
have
to
reconfigure
the
blade
server.
Note:
The
blade
server
is
a
hot-swap
device,
and
the
blade
bays
in
the
BladeCenter
unit
are
hot-swap
bays.
Therefore,
you
can
install
or
remove
the
blade
server
without
removing
power
from
the
BladeCenter
unit.
However,
you
must
turn
off
the
blade
server
before
removing
it
from
the
BladeCenter
unit.
Complete
the
following
steps
to
remove
the
blade
server:
1.
Read
the
safety
information
beginning
on
page
iii
and
“Installation
guidelines”
on
page
71
2.
If
the
blade
server
is
operating,
the
power-on
LED
is
lit
continuously
(steady).
Shut
down
the
operating
system
by
typing
the
shutdown
-h
now
command.
Refer
to
your
operating
system
documentation.
If
the
blade
server
was
not
turned
off,
press
the
power-control
button
(behind
the
blade-server
control-panel
door)
to
turn
off
the
blade
server.
See
“Blade
server
controls
and
LEDs”
on
page
14
for
more
information
about
the
location
of
the
power-control
button.
Attention:
Wait
at
least
30
seconds
for
the
hard
disk
drives
to
stop
spinning,
before
proceeding
to
the
next
step.
3.
Open
the
two
release
levers
as
shown
in
the
illustration.
The
blade
server
moves
out
of
the
bay
approximately
0.6
cm
(0.25
inch).
4.
Pull
the
blade
server
out
of
the
bay.
5.
Place
either
a
filler
blade
or
a
new
blade
server
in
the
bay
within
1
minute.
