The following illustration shows how to install DIMMs on the system board for the blade server. DIMM socket 1 (J1) DIMM socket 2 (J5) DIMM socket 3 (J2) DIMM socket 4 (J6) Before you begin, read the documentation that comes with the DIMMs. Complete the following steps to install a DIMM: 1. Read the safety information beginning on page vii and "Installation guidelines" on page 19. 2. Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter unit (see "Removing the blade server from the BladeCenter unit" on page 20 for instructions). 3. Carefully lay the blade server on a flat, static-protective surface. 4. Open the blade server cover (see "Opening the blade server cover" on page 22 for instructions). 5. Locate the DIMM connectors on the system board. Determine the connectors into which you will install the DIMMs. 6. Touch the static-protective package that contains the DIMM option to any unpainted metal surface on the BladeCenter unit or any unpainted metal surface on any other grounded rack component in the rack you are installing the DIMM option in for at least 2 seconds. Then, remove the DIMM from the package. 7. 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. 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 properly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert the DIMM. 8. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 35. 26 BladeCenter HS20 Type 8832: Installation and User's Guide

The
following
illustration
shows
how
to
install
DIMMs
on
the
system
board
for
the
blade
server.
DIMM socket 1 (J1)
DIMM socket 2 (J5)
DIMM socket 3 (J2)
DIMM socket 4 (J6)
Before
you
begin,
read
the
documentation
that
comes
with
the
DIMMs.
Complete
the
following
steps
to
install
a
DIMM:
1.
Read
the
safety
information
beginning
on
page
vii
and
“Installation
guidelines”
on
page
19.
2.
Shut
down
the
operating
system,
turn
off
the
blade
server,
and
remove
the
blade
server
from
the
BladeCenter
unit
(see
“Removing
the
blade
server
from
the
BladeCenter
unit”
on
page
20
for
instructions).
3.
Carefully
lay
the
blade
server
on
a
flat,
static-protective
surface.
4.
Open
the
blade
server
cover
(see
“Opening
the
blade
server
cover”
on
page
22
for
instructions).
5.
Locate
the
DIMM
connectors
on
the
system
board.
Determine
the
connectors
into
which
you
will
install
the
DIMMs.
6.
Touch
the
static-protective
package
that
contains
the
DIMM
option
to
any
unpainted
metal
surface
on
the
BladeCenter
