Maintenance and Modifications
Opening and Closing the Switcher
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.
To prevent electric shock, always unplug the ISM 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
(figure 7-1).
