10. Replace the top cover on the ISM.
11. Fasten the top cover with the screws that were removed in step 3 and step 4.
12. Rack mount the switcher if desired and reconnect all cables.
Installing a Firmware Upgrade
In some cases the ISM firmware may require replacement with an updated version. There
are nine user-replaceable firmware chips (see figure 50): U1, U2, and U6 on the front panel
circuit board and U98, U99, U100, U101, U102, and U103 on the main circuit board. The
U-numbers are printed on the circuit boards. Extron recommends that you send the unit in
to Extron for service and updates.

factory.
Replace firmware in the ISM as follows:
CAUTION: Electric shock hazard. To prevent electric shock, always unplug the
ISS from the AC power source before opening the enclosure.
1. Open the switcher (see Opening and Closing the Switcher on page 64).
2. Locate the firmware chips to be replaced on the main or front panel circuit board (see
figure 50).
3. After you are electrically grounded, use a DIP chip puller to grasp each IC chip and pull
it out of the sockets.
