that the notches in the DIMM align with the tabs in the slot (see Figure 2–15).
2. Press the DIMM gently into the slot until seated at both ends.
3. Engage both retaining clips for the DIMM.
4. Repeat step 1 through step 3 for each DIMM.
5. Install the cache module using the steps in either “Installing the Cache Module in a
Single-Controller Configuration,” page 2–15, or “Installing a Cache Module in a
Dual-Redundant Controller Configuration,” page 2–33.
