10. Verify that the new logic board has microcode modules installed. If not, you must transfer the modules
from the logic board you are replacing to the new board.
Use Module Extractor PN 73G5523 for modules on all levels of the logic board, or PN 10G3902 for
Model A00 late-level and Models 001 and 002 logic board and attachment card microcode modules.
11. Verify that the microcode modules are properly oriented and plugged into the socket.
Attention: When using module extractor PN 73G5523, follow these steps to avoid cracking or
damaging the plastic sockets.
a. Insert the C-shaped end of the tool into one of the module socket extraction slots.
b. Hold the tool perpendicular to the module and pull upward to loosen it from the socket.
c. Repeat the previous 2 steps, using the extraction slot in the opposite corner, until the module lifts
out of the socket.
d. Visually inspect module leads for alignment. Correct any mis-alignment before reinstalling into new
board socket.
