Use this information to install a DIMM.
Read the safety information in Safety and Installation guidelines.
If you are installing an optional device in the server,
you need to slide the server out from the rack enclosure, turn off
the server and peripheral devices, and disconnect the power cords
and all external cables.
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.
The following illustration shows the location of the DIMM
connectors on the system board.
Figure 1. The location of the DIMM connectors on the system board
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. DIMM installation sequence. Two column
table for documenting the number of DIMMs and installation sequence
(connectors).
| Number of DIMMs |
Installation sequence (connectors) |
| First pair of DIMMs |
1, 3 |
| Second pair of DIMMs |
2, 4 |
- 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.
Figure 2. 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.
If you have other devices to install, do so now.
Otherwise, go to Completing the installation.
