Stand-alone Installation En_9
The VOS-8FOM-D232T transmitter/VOS-8FOM-D232R receivercan be mounted into a rackor can
be used as astand-alone module. As a stand-alone module, the unit can be placed on a desktop
or canbe mountedto awall.
NOTE: Before mounting the VOS-8FOM-D232T transmitter/VOS-8FOM-D232R receiver, please
ensure that there is adequate space at both ends forviewing the front-panel LEDsand for making
the variousrear-panel cableconnections.

Rack-mount Installation En_10
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 tocover 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.
VOS-CH04:
19 inch4U,14 video card slots, suit for 1-ch,2-ch,4-ch,8-ch(two slots)video cards.
Support oneslide-in power supply AC100V~AC240V
VOS-CH06:
19 inch6U,16 video card slots, suit for 1-ch,2-ch,4-ch,8-ch(two slots)video cards.
Support two slide-in power supply AC100V~AC240V, one for redundancy.

The VOS-8FOM-D232Ttransmitter/VOS-8FOM-D232R receivercan be installed into our rack mount
chassis,VOS-CH04 orVOS-CH06, whichcan be mounted into an industry-standard 19-inch
equipment rack.
