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:
1. Read the safety information that begins on page vii and “Installation guidelines”
2. Turn off the server and all peripheral devices; then, disconnect the power
cords and all external cables.
3. Remove the bezel (see “Removing the bezel” on page 25).
4. Carefully turn the server on its side so that it is lying flat, with the cover facing
up.
Attention:
Do not allow the server to fall over.
5. Remove the side cover (see “Removing the side cover” on page 25).
6. Remove the air duct.
7. 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 6. DIMM installation sequence
