A front view illustration of a typical Cougar3 video frame, equipped with a local control panel, showing
location of key components is shown by Figure 2-1. Removing the front cover provides access to the
video router board; primary and, if equipped, secondary power supply or system controller modules; and
rear panel of the local control panel, if present.

If the Cougar3 router is installed using the PRC communication bus with an external system controller,
a minimum of one power supply module is required – installed in the primary power supply module
slot. A second power supply module may be installed in the secondary slot for power redundancy. Each
Cougar3 power supply module also contains cooling fans for the chassis and a fan controller circuit that
monitors and controls operation of the fans.
In stand-alone configuration, the Cougar3 video frame is factory equipped with a small-scale System
Controller/Power Supply Module installed in the primary controller slot that combines functions of
system controller and power supply into a single removable unit. The system controller (SSC3) oversees
operation of entire system – router frame and control panels and communicates with other system
components through an Ethernet interface. One SSC3 module is required per system; a second
controller may be installed at any time, using the secondary controller slot, to add full redundant control
capability. Each SSC3 module also contains cooling fans for the chassis and a fan controller that
monitors and controls operation of the fans.
In PRC or stand-alone configurations, video switching and interface circuitry is contained on the Video
Router Circuit Board. In addition, the board is equipped with front edge status lights that provide a
visual indication of the active system controller and system errors. The board also provides power and
dedicated Ethernet connection points for a local control panel.
