To install the optional DVI output card, the switcher case must be removed.
Remove as follows:
1.Disconnect the AC power cord to remove power from the switcher.
WTo prevent electric shock, always unplug the switcher from the AC power source before opening the enclosure.
2.If the switcher is installed in a rack, disconnect all signal and control cables and remove the switcher from the rack.
3.Remove the 16 screws from the switcher, 8 on the top and 4 on each side of the cover (figure 1).
4. | Remove the top two front panel screws. |
5. | Lift the top cover straight up approximately five inches for access |
