9. Insert the DIMM into the connector by aligning the edges of the DIMM with the
slots at the ends of the DIMM connector.
10. 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 seated in the connector. 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.

b. Press the memory card into the connector and close the retention levers.
If you have other options to install or remove, do so now; otherwise, go to
"Completing the installation" on page 49.
Hot-swapping DIMMs
To hot-swap DIMMs, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 21.
Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which could
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when working
inside the server with the power on.
2. Remove the front cover (tower model only), and the top cover (see "Removing
the front cover, top cover, and bezel" on page 23).
Attention: When moving the memory card, do not allow it to touch any
components or structures inside the server.
Make sure that the memory hot-swap enabled LED is lit.
