Figure 26. Opening retaining clip
Attention: If necessary, due to space constraints, you can use a pointed tool to open the retaining
clips. Place the tip of the tool in the recess on the top of the retaining clip; then, carefully rotate the
retaining clip away from the DIMM connector. Pencils are not recommended, as they may not be
strong enough.
Step 4.
Make sure that both retaining clips on the DIMM connector from which you are removing the DIMM
are in the fully-open position; then, pull the DIMM out of the connector.
Figure 27. DIMM removal
Attention: To maintain proper system cooling, do not operate the compute node without an air
baffle installed over the DIMM connectors.
Notes:
• If you are not immediately replacing the DIMM, install the air baffle (see "Install the air baffle" on
page 32).
• Retaining clips on the DIMM connectors must be in the closed position to install the air baffle.
