Installing SlMMs
Follow these steps to install SIMMs:
1 Remove the computer’s cover as described on page 3-2.
2 Remove any option cards that may be blocking your access to the SIMM sockets (see
page 3-5).
3 The SIMM sockets are located near the front of the computer. Install the first SIMM
in the socket farthest from the edge of the main system board. Note that both SIMM
sockets must be occupied with the same size SIMM or the system will not work
properly.
4 Position each SIMM so its component side is toward the left side of the computer;
then insert it in the socket at a slight angle. (See Figure 3-7.)
5
Gently press down on the SIMM and, at the same time, press the top corners forward
until the SIMM is vertical and clicks into place between the metal clips and the
retaining posts. Make sure the SIMM is fully inserted into the socket and that the
retaining post pins fit into the holes at each end of the SIMM.
6 Repeat steps 4 and 5 for each SIMM you want to install.
7 Replace any option cards you removed and the cover.
8
Run the SETUP program immediately in order to update the computer’s configuration
with the new memory information.
