Installation Instructions
Typical Configurations:
1:Install the video card into a standard 19inch rack, usinguser-supplied rack-mounting
hardware. Becareful to not damage exposed objects on the back of the card cage unit.
2:If asecondary earth ground connectionis needed, a grounded wire with a ground lug can be
attached to the rackusing the protruding screw provided on the right side of the chassis.
3:If desired, blank panels may beinstalled to cover unused slots. A single blank panel coversa
single slot opening.
4:Each fiber optic plug-in module is equipped with a POWER LED indicator that illuminates
when power is applied to the rack unit.
5:Fiber optic plug-in modules(video cards) can be installed into anyof theavailable 14slots
of thecard cage. Most modules require onlya single slot width, but others, such as the 8-Ch
video Series, require two slot widths.
