Opening and Closing the Switcher

NOTE: Extron recommends that you send the unit in to Extron for service and updates.

To replace the firmware or install the optional DVI output card, you need to open the ISM’s
case. Open and close the switcher as follows:

1.

Disconnect the AC power cord from the ISM to remove power from the unit.

CAUTION: Electric shock hazard. To prevent electric shock, always unplug the

ISS from the AC power source before opening the enclosure.

2.

If the ISM is installed in a rack, disconnect all signal and control cables and remove the
ISM from the rack.

3.

Remove the 16 screws, 8 on the top and 4 on each side of the ISM cover (see figure 49
on the next page).
