Removing the blade server from the BladeCenter unit Attention: v To maintain proper system cooling, do not operate the BladeCenter unit for more than 1 minute without a blade server or filler blades installed in each blade bay. v Note the number of the bay that contains the blade server before you remove it. You must reinstall the blade server 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 unexpected consequences, such as incorrect reconfiguration of 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. Removing the blade server The blade server is a hot-swappable device, and the blade bays in the BladeCenter unit are hot-swappable 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: Releasehandles open Figure 8. Removing the blade server 1. Read the safety information beginning on page vii and "Installation guidelines" on page 19. 2. If the blade server is operating, the power on LED is lit continuously (steady). Before you remove a blade server from the BladeCenter unit, you must shut down the operating system on it by typing the shutdown -h now command or choosing the shut down option from your GUI. See "Turning off the blade server" on page 10 for details. You do not have to shut down the BladeCenter unit itself. 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
Attention:
v
To
maintain
proper
system
cooling,
do
not
operate
the
BladeCenter
unit
for
more
than
1
minute
without
a
blade
server
or
filler
blades
installed
in
each
blade
bay.
v
Note
the
number
of
the
bay
that
contains
the
blade
server
before
you
remove
it.
You
must
reinstall
the
blade
server
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
unexpected
consequences,
such
as
incorrect
reconfiguration
of
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.
Removing
the
blade
server
The
blade
server
is
a
hot-swappable
device,
and
the
blade
bays
in
the
BladeCenter
unit
are
hot-swappable
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
vii
and
“Installation
guidelines”
on
page
19.
2.
If
the
blade
server
is
operating,
the
power
on
LED
is
lit
continuously
(steady).
Before
you
remove
a
blade
server
from
the
BladeCenter
unit,
you
must
shut
down
the
operating
system
on
it
by
typing
the
shutdown
-h
now
command
or
choosing
the
shut
down
option
from
your
GUI.
See
“Turning
off
the
blade
server”
on
page
10
for
details.
You
do
not
have
to
shut
down
the
BladeCenter
unit
itself.
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.
