Introduction
The information in this manual covers the installation of the VF-SR-20/2 Fiber-Optic Card Cage and
Power Supply. This system should only be installed by a qualified technician using approved materials
and wiring practices in accordance with the National Electrical Code ANSI/NFPA 70, state, and local
electrical codes.
Read these instructions thoroughly before beginning an installation.
Functional Description
The VF-SR-20/2 provides rack mounting and power for Vicon fiber-optic rack modules. The VF-SR-20/2
mounts into a standard EIA 19-inch racking system. It can accommodate up to 14 single slot modules in
any combination of receivers and transmitters.
The VF-PSR-2 DC power supply is included and supplies a 100 W of output power. It has a universal
power input of 85 to 264 VAC. For unused slots, a blank panel is available, Model VF-BPS.
Installation
The VF-SR-20/2 may be mounted, using standard hardware, in an upright position, with the backplane
upward, inside the cabinet (see diagram below). It is important, as with any electronic equipment, to
provide sufficient airflow to prevent over heating in the cabinet. At least 1-7/8" (1 RU) of space should be
allowed above and below the VF-SR-20/2 to provide air flow. If more than one VF-SR-20/2 is installed,
forced airflow may be necessary depending upon the number of plug-in cards used in the over-all
installation. It is necessary to add a 1 RU fan unit at the top of every three VF-SR-20/2 racks with 1 U
spacing between them.
All cards are inserted in a similar manner. Any card may be used in any slot. Insert the card all the way
until the edge fingers meet the internal bus connector and the front panel is even with the front of the
rack. Then secure the ¼-turn fasteners by pushing with a small screwdriver, turning the screw 90
degrees clockwise and releasing pressure.
Power Supply
The far right hand position of the VF-SR-20/2 is only compatible with a VF-PSR-2 plug-in power supply.
