Align the notch and then slide the contact edge of the SIMM into the SIMM slot at about a 45-degree angle, as shown in Figure 5-3.

Once you have the SIMM aligned properly, maintain slight pressure toward the slot and pivot the SIMM upward toward the vertical until it snaps into place, as shown in Figure 5-4. Verify that the spring connectors on each side of the SIMM slot bracket have both snapped into the matching holes on the SIMM.

To remove a SIMM

Locate the spring connectors at the top of each side of the SIMM slot bracket and press both of them lightly at the same time while simultaneously pressing the SIMM gently away from the vertical. After the spring connectors release their grip on the SIMM, pivot the SIMM gently downward to about a 45-degree angle and then pull it gently out of the slot.
