DOWNFRAMING TO THE CM9760-MXBL

When more than 128 video inputs and a maximum of 16 video outputs are required in a system that also requires looping, the CM9760-MXBL must be used to loop out the video. The CM9760-MXBL is a downframed matrix bay that does not require power. The CM9760-MXBL accommodates up to sixteen CM9760-DFL cards to loop out video. Note that front panel video input and output cards are not used in the CM9760-MXBL.

Figure 59 illustrates a sample CM9760-MXBL downframe configuration containing a total of 256 video inputs and 16 video outputs.
