4.2.4 Installing a SIMM
Follow these steps to install a SIMM:
1. Carefully slip a SIMM at a 45° angle into a socket making sure that the curved
edge indicating the pin 1 of the SIMM matches pin 1 of the socket.
A SIMM fits only in one direction. If you slip
in a SIMM but it does not completely fit, you
may have inserted it the wrong way.
Reverse the orientation of the SIMM.
2. Gently push the SIMM to a vertical position until the pegs of the socket slip
into the holes on the SIMM, and the holding clips lock the SIMM into
position. The SIMM should be at a 90° angle when installed.
