Upgrades and Repairs
You can perform the following upgrades and repairs to the SGS 408:
• Installing the DVI connector option (see below)
• Replacing the AC fuse (page B-3)
• Installing a firmware update (page B-4)
Before completing any of these procedures, follow the instructions in “Internal
access”, below.
Internal access
Upgrades and fuse replacement require access to the internal areas of the
switcher. To gain access to the internal areas, do the following:
1. Remove the power cable from the switcher and from the power source.
Do not open the cover of the switcher without unplugging the power
cord.
2. If the switcher is rack mounted, remove the input and output cables from it
and remove the unit from the rack. If the switcher is not rack mounted, you
do not need to remove the input and output cables.
3. Remove 16 screws from the sides and top of the cover and the two #10
screws from the top half of the front panel (figure B-1).
Figure B-1 — Removing the cover
4. Remove the cover by slightly lifting each side alternately until the cover is
free.
Reverse this procedure to reinstall the cover.
Installing the DVI connector option
After following the instructions in “Internal access” to remove the cover, do the
following:
1. Remove the two screws that hold the DVI connector cover in place (figure
B-2), and set the cover aside. You will not need it.
