To remove a DIMM, complete the following steps.
Step 1. Before you begin, read “Safety” on page iii and “Installation guidelines” on page 17.
Step 2. If the blade server is installed in a BladeCenter unit, remove it (see “Removing the blade server
from the BladeCenter unit” on page 19).
Step 3. Remove the blade server cover (see “Removing the blade server cover” on page 20).
Step 4. If an optional expansion unit is installed, remove the expansion unit (see “Removing an optional
expansion unit” on page 22).
Step 5. Locate the DIMM connectors (see “Blade server connectors” on page 14). Determine which DIMM
you want to remove from the blade server.
Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the
clips gently.
Step 6. Move the retaining clips on the ends of the DIMM connector to the open position by pressing the
retaining clips away from the center of the DIMM connector.
Note: To access DIMM connector seven through twelve, use your fingers to lift the DIMM access
door.
