Use this information to install a DIMM.
Read the safety information in Safety and Installation guidelines.
If you are replacing a server component in the water-cooled technology tray, you need to remove the water-cooled technology tray from the chassis enclosure and refer to the Removing a water-cooled technology tray from a chassis and Installing a water-cooled technology tray in a chassis sections.
Attention: Static electricity that
is released to internal server components when the server is powered
on might cause the server to halt, which might result in the loss
of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when you work inside the server
with the power on.
To install a DIMM, complete the following steps.
- Remove the cover (see Removing the cover).
- Locate the DIMM connectors on the system board. Determine
the connectors into which you will install the DIMMs. Install the
DIMMs in the sequence shown in the following table.
Table 1. Normal mode DIMM installation sequence. Two column
table documenting the number of installed microprocessor and DIMM
connector population sequence.

4, 13 |
- Open the retaining clip on each end of the DIMM connector.
Attention:
- To avoid breaking the retaining clips or damaging the DIMM connectors,
open and close the clips gently.
- Unpopulated DIMM slots must be filled with DIMM fillers in order
to provide proper cooling.
Figure 1. DIMM installation
- Touch the static-protective package that contains the DIMM
to any unpainted metal surface on the outside of the server. Then,
remove the DIMM from the package.
- Turn the DIMM so that the alignment slot align correctly
with the alignment tab.
- Insert the DIMM into the connector by aligning the edges
of the DIMM with the slots at the ends of the DIMM connector.
- Firmly press the DIMM straight down into the connector
by applying pressure on both ends of the DIMM simultaneously. The
retaining clips snap into the locked position when the DIMM is firmly
seated in the connector.
Note: If there is a gap between the DIMM and the retaining clips,
the DIMM has not been correctly inserted; open the retaining clips,
remove the DIMM, and then reinsert it.
- Install the DIMM cover.
Figure 2. DIMM installation
- Reinstall the cover (see Replacing the cover).
If you have replaced a server component or installed
an optional device in the server, you need reinstall the cover, slide
the server into the rack, reconnect the power cords and all external
cables, and turn on the server and peripheral devices.
