IBM 436854u - System x3200 M2 5U Mini Tower Server User Manual page 43

The following illustration shows the dual inline memory module (DIMM) connectors
and corresponding LEDs 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 v and "Installation guidelines"
on page 20.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables.
3. Remove the side cover (see "Removing the side cover" on page 24).
4. 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.
