7.
Press the raised lever on the left and right tabs at the same time to
release the SIMM module. As each SIMM is released, it turns slightly.
8.
Remove all SIMM modules from the board. These modules contain
the PAL and AMP information for your control. You may want to
label these modules before storing them. You will need to reinstall the
modules when you receive the new or repaired CPU board.
9.
When you receive your replacement CPU board, install it into the
component enclosure as shown in Figure 15B.3. If you have extended
memory, you need to set the jumper shown in Figure 15B.4 before
you install the module.
