to open the cabinet and then continue with step 2.
________ Electro-Static Discharge (ESD) can damage IC chips, even when it is not
enough to be humanly detected (felt, heard or seen). Do NOT touch IC chips
without being electrically grounded. (Read warning on page 4-2.)
2. With the top cover off the Matrix, unplug the cable that connects the Front
Panel to the Main Controller board and put it aside.
3. Remove the four (4) screws that hold the QuickSwitch Front Panel Controller
(QS-FPC) to the Matrix cabinet.
Figure 4-23. Remove the Front Panel to access the Software IC Chip.
4. Place the QS-FPC face down on a clean workspace. If necessary, place it on
a soft pad to prevent damage.
_________ Be sure you are electrically grounded.
Figure 4-24. Use the PLCC Chip Puller to remove the Software IC Chip.
5. Use the PLCC IC puller to remove the old Software chip. Squeeze the tool to
align the hooks with the slots provided in opposite corners of chip socket U8.
Insert the hooks, squeeze gently and pull the IC straight out of the socket.
Set the chip aside.
6. Note the orientation of the angled corner of the new Software chip. Orient this
to match the angled corner of the socket and carefully press it in place.
7. Reinstall the cover on the back of the QS-FPC, and reverse the above
procedure to put the Matrix back in place.
