Replacing Main Memory SIMMs

SIMMs are manufactured with a polarization notch to prevent them from being installed backward.
Figure 5-7 shows the polarization notch and locations of the alignment holes on a main memory
SIMM card. The main memory SIMM cards are installed with the connector edge down and the
component side facing in, as shown in the upper right of Figure 5-5 and Figure 5-6.
