1.4.2 How to install a DIMM Module
1. The DIMM socket has a “ Plastic
Safety Tab” and the DIMM memory
module has an asymmetrical notch”, so
the DIMM memory module can only
fit into the slot in one direction.
2. Push the tabs out. Insert the DIMM
memory modules into the socket at a
90-degree angle then push down
vertically so that it will fit into place.
3. The Mounting Holes and plastic
tabs should fit over the edge and hold
the DIMM memory modules in place.
