IBM BladeCenter HS22V Installation And User Manual page 49

To install a DIMM, complete the following steps:
1. Before you begin, read "Safety" on page v and "Installation guidelines" on
page 19.
2. Read the documentation that comes with the DIMMs.
3. If the blade server is installed in a BladeCenter unit, remove it (see
"Removing the blade server from the BladeCenter unit" on page 21 for
instructions).
4. Carefully lay the blade server on a flat, static-protective surface.
5. Open the blade server cover (see "Removing the blade server cover" on page
22 for instructions).
6. If an expansion unit is installed and you are installing DIMMs on the system
board, remove the expansion unit (see "Removing an optional expansion unit"
on page 24).
7. Locate the DIMM connectors (see "Blade server connectors" on page 18).
Determine which DIMM connectors you will be installing memory into.
8. If you are installing a DIMM in DIMM connectors ten through eighteen,
remove the front bezel (see "Removing the bezel assembly" on page 28).
9. If a DIMM filler or another memory module is already installed in the DIMM
connectors, remove them (see "Removing a memory module" on page 34).
Note: A DIMM or DIMM filler must occupy each DIMM socket before the
blade server is turned on.
10. To install the DIMMs, repeat the following steps for each DIMM that you
install:
DIMM
a. Make sure that the retaining clips are in the open position, away from the
center of the DIMM connector.
b. Touch the static-protective package that contains the DIMM to any
unpainted metal surface on the BladeCenter unit or any unpainted metal
surface on any other grounded rack component in the rack in which you
are installing the DIMM for at least two seconds; then, remove the DIMM
from its package.
c. Turn the DIMM so that the DIMM keys align correctly with the DIMM
connector on the system board.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
d. Press the DIMM into the DIMM connector. The retaining clips will lock the
DIMM into the connector.
e. Make sure that the small tabs on the retaining clips are in the notches on
the DIMM. If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly installed. Press the DIMM firmly into the
Retaining
clip
