SIMM Information
To Remove a SIMM from a SIMM Socket:
Bend thetwo retaining pods out of the way...
just far enough to remove the SIMM
Figure 34 - Removing SIMMs
l CarefuZZy spread open the retaining posts found on each end of the SIMM. Only spread the
posts as far apart as needed to clear the board; these posts can easily break if too much force
is applied. If broken, it will be very difficult to secure a new SIMM back into that socket. We
suggest spreading one post at a time; that way it’s easier to control the amount of pressure
being applied to remove the SIMM.
l Once the retaining posts are out of the way, tilt the SIMM toward you, and lift up and out of
the socket.

l Place the connector edge of the SIMM into the SIMM Socket, pressing down slightly. The latching
holes on each end of the SIMM will line up with the latching posts when the SIMM is seated
properly.
l Tilt the SIMM back into the socket until the retaining posts snap in front of the SIMM. A properly
installed SIMM should look like this:
