Note:
DIMM connectors 7, 8, 15, and 16 are not used in memory-mirroring mode.
When you install or remove DIMMs, the server configuration information changes.
When you restart the server, the system displays a message that indicates that the
memory configuration has changed.
The following illustration shows how to install DIMMs on the system board.
Attention:
Static electricity that is released to internal server components when
the server is powered-on might cause the server to stop, 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:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 28.
2. Turn off the server and peripheral devices; then, disconnect the power cords
and all external cables.
3. Remove the left-side cover (see “Removing the left-side cover” on page 48).
4. Remove the hot-swap power supply or power supplies from the server.
