Installing a memory module
If you are replacing a DIMM, read the following information:
v Only DIMM replacement is supported. Installation of additional DIMMs is not
supported.
v
Install the replacement DIMM in the same slot from which you remove the
defective DIMM.
v
Make sure that the replacement DIMM is the correct type of memory (see
Chapter 3, “Parts listing,” on page 59 for a list of DIMMs that are compatible with
the server).
To install a DIMM, complete the following steps.
Retaining
clip
DIMM
1. Read the documentation that comes with the DIMM.
2. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the outside of the system-board tray; then, remove the DIMM
from the package.
Attention: To avoid breaking the DIMM retaining clips or damaging the DIMM
connectors, open and close the clips gently.
3. Make sure that both of the retaining clips are in the fully open position.
4. Orient the DIMM so that the DIMM keys align correctly with the connector on
the system board.
5. Insert the DIMM by pressing the DIMM along the guides into the connector.
Make sure that the retaining clips snap into the closed positions.
Attention: 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.
6. Install the expansion enclosure, if you removed one (see “Installing an
expansion enclosure on a system-board tray” on page 74); otherwise, install the
system-board tray cover (see “Installing the system-board tray cover” on page
122).
7. Install the system-board tray in the chassis (see “Installing the system-board
tray in a 2U chassis” on page 76 or “Installing the system-board tray in a 3U
chassis” on page 78).
