The ‘rubber’ side guards should be slid off and removed. The guards and cage are designed to prevent movement and loosening of the RAM modules when subjected to shock and vibration. Removing the guards allows the free movement of each RAM insertion mechanism. The guards are designed to then lock the RAM units together in the same orientation once installed. Use a torch and magnifying glass to see how guards attach into the top of the spring clip arms. The two RAM clips must be re-connected to the guard simultaneously at the same angle.
