1. Slide the new CPU board halfway into the same location in the case previously occupied by
the old board. Be sure to position the board into the plastic guides located at the bottom of the
case. The side of the board with all the connections on it should face to the right.
2. Connect the 16-pin end of the new UL I/O ribbon cable (734-038), the same cable that you
have previously attached to the UL I/O card, to the position on the new CPU card shown in
Figure 7 (on next page). This cable is not keyed. Make sure to attach the cable so that the
colored stripe is closest to the front of the case. Refer to Figure 7.
3. Slide the new CPU board the rest of the way into chassis, inserting it in the bus fixture in the
back.
Note: After the board has been inserted most of the way, you may feel some
resistance. You will need to apply some force to connect the board to the bus
fixture.
4. Reinsert the screw at the top of the case with the T15 Torx screwdriver. This completely
fastens the new board in place.
5. Refer to Figure 7 and match up the labels on the cables to the labeled positions on the new
CPU board. Attach each cable to the new board so that the colored stripe is on the bottom.
