SIDEFRAMING AND DOWNFRAMING
Sideframing, downframing, or a combination of both sideframing and downframing is required for installation of multiple matrix bays in a 9760
system:
• When expanding video inputs beyond 256 as provided by a single matrix bay, the expansion of video inputs occurs in a horizontal manner
using a sideframing configuration. As a result, additional matrix bays must be installed in nearby racks. For detailed information, refer to
the Sideframing section.
• When expanding video outputs beyond 16 as provided by a single matrix bay, the expansion of video outputs occurs in a vertical manner
using a downframing configuration. As a result, additional matrix bays must be installed in the same rack. For detailed information, refer to
the Downframing section.
• When expanding video inputs beyond 256 and video outputs beyond 16, a combination of sideframing and downframing is used. The
maximum capacity of a single-node system is 2,048 video inputs and 128 video outputs. For detailed information, refer to the Using a
Combination of Sideframing and Downframing section.
NOTE: When using CM9760-MDA units, you can increase the video output capacity to a maximum of 512.
• When more than 128 video inputs and a maximum of 16 video outputs are required in a system that also requires looping, downframing to
the CM9760-MXBL is required to loop out the video. For detailed information, refer to the Downframing to the CM9760-MXBL section.
