Maintenance and Modifications

Opening and Closing the Switcher

To replace the firmware or install the optional DVI output card, you will need to
open the ISS’s case. Extron recommends that you send the unit in to Extron for
service and updates.
Open and close the switcher as follows:
1. Disconnect the AC power cord from the ISS to remove power from the unit.
To prevent electric shock, always unplug the ISS from the AC power
source before opening the enclosure.
2. If the ISS is installed in a rack, disconnect all signal and control cables and
remove the ISS from the rack.
3. Remove the 16 screws, 8 on the top and 4 on each side of the ISS cover
(figure 7-1).
