Complete the following steps to install a DIMM: 1. Read the safety information beginning on page iii and "Installation guidelines" on page 71 2. If the blade server is operating, 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. 3. Remove the blade server from the BladeCenter unit. See "Removing the blade server from the BladeCenter unit" on page 73 for instructions. 4. Carefully place the blade server on a flat, static-protective surface. 5. Open the blade server cover. See "Opening the blade server cover" on page 74 for instructions. 6. Locate the DIMM connectors on the system board. Determine the connectors into which you will install the DIMMs. The blade server comes with two 256 MB DIMMs installed in the DIMM 3 (J32) and DIMM 4 (J40) memory connectors. When you install additional DIMMs, be sure to install them as a pair, in DIMM connectors 1 and 2 (J25 and J28). Install the DIMMs in the following order: Pair First Second DIMM connectors 3 and 4 (J32 and J40) 1 and 2 (J25 and J28) 7. Touch the static-protective package that contains the DIMM option to any unpainted metal surface on the BladeCenter chassis or any unpainted surface on any other grounded rack component. Then, remove the DIMM from the package. 8. To install the DIMMs, repeat the following steps for each DIMM that you install: a. Turn the DIMM so that the DIMM keys align correctly with the connector on the system board. Ensure that the retaining clips are open. Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently. b. Insert the DIMM by pressing the DIMM along the guides into the connector. Make sure that the retaining clips snap into the closed positions. Important: If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert the DIMM. 9. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 90. Installing an I/O expansion card You can add an optional I/O expansion card (adapter) to the blade server to give the blade server additional network connections for communicating on a network. When you add an I/O expansion card, you must make sure that the switch modules in I/O bays 3 and 4 on the BladeCenter unit both support the I/O expansion card network-interface type. For example, if you add an Ethernet expansion card to the blade server, the modules in I/O bays 3 and 4 on the BladeCenter unit must both be compatible with the Ethernet expansion card. All other I/O expansion cards installed on other blade servers in the BladeCenter unit must also be compatible Chapter 9. Installing options 79

Complete
the
following
steps
to
install
a
DIMM:
1.
Read
the
safety
information
beginning
on
page
iii
and
“Installation
guidelines”
on
page
71
2.
If
the
blade
server
is
operating,
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.
3.
Remove
the
blade
server
from
the
BladeCenter
unit.
See
“Removing
the
blade
server
from
the
BladeCenter
unit”
on
page
73
for
instructions.
4.
Carefully
place
the
blade
server
on
a
flat,
static-protective
surface.
5.
Open
the
blade
server
cover.
See
“Opening
the
blade
server
cover”
on
page
74
for
instructions.
6.
Locate
the
DIMM
connectors
on
the
system
board.
Determine
the
connectors
into
which
you
will
install
the
DIMMs.
The
blade
server
comes
with
two
256
MB
DIMMs
installed
in
the
DIMM
3
(J32)
and
DIMM
4
(J40)
memory
connectors.
When
you
install
additional
DIMMs,
be
sure
to
install
them
as
a
pair,
in
DIMM
connectors
1
and
2
(J25
and
J28).
Install
the
DIMMs
in
the
following
order:
Pair
DIMM
connectors
First
3
and
4
(J32
and
J40)
Second
1
and
2
(J25
and
J28)
7.
Touch
the
static-protective
package
that
contains
the
DIMM
option
to
any
unpainted
metal
surface
on
the
BladeCenter
chassis
or
any
unpainted
surface
on
any
other
grounded
rack
component.
Then,
remove
the
DIMM
from
the
package.
8.
To
install
the
DIMMs,
repeat
the
following
steps
for
each
DIMM
that
you
install:
a.
Turn
the
DIMM
so
that
the
DIMM
keys
align
correctly
with
the
connector
on
the
system
board.
Ensure
that
the
retaining
clips
are
open.
Attention:
To
avoid
breaking
the
retaining
clips
or
damaging
the
DIMM
connectors,
handle
the
clips
gently.
b.
Insert
the
DIMM
by
pressing
the
DIMM
along
the
guides
into
the
connector.
Make
sure
that
the
retaining
clips
snap
into
the
closed
positions.
Important:
If
there
is
a
gap
between
the
DIMM
and
the
retaining
clips,
the
DIMM
has
not
been
correctly
installed.
In
this
case,
open
the
retaining
clips
and
remove
the
DIMM;
then,
reinsert
the
DIMM.
9.
If
you
have
other
options
to
install
or
remove,
do
so
now;
otherwise,
go
to
“Completing
the
installation”
on
page
90.
Installing
an
I/O
expansion
card
You
can
add
an
optional
I/O
expansion
card
(adapter)
to
the
blade
server
to
give
the
blade
server
additional
network
connections
for
communicating
on
a
network.
When
you
add
an
I/O
expansion
card,
you
must
make
sure
that
the
switch
modules
in
I/O
bays
3
and
4
on
the
BladeCenter
unit
both
support
the
I/O
expansion
card
network-interface
type.
For
example,
if
you
add
an
Ethernet
expansion
card
to
the
blade
server,
the
modules
in
I/O
bays
3
and
4
on
the
BladeCenter
unit
must
both
be
compatible
with
the
Ethernet
expansion
card.
All
other
I/O
expansion
cards
installed
on
other
blade
servers
in
the
BladeCenter
unit
must
also
be
compatible
