PESA’s Cheetah Series Video Matrix Switcher products are manufactured using a “building block”
architecture of core components installed in a chassis frame that provides the infrastructure
requirements of circuit card capacity, power, cooling and system control I/O connections. There are
several different types of chassis frames in the Cheetah family, of which the 864XR is a member. Each
frame is designed for a specific purpose – but most are built with a degree of flexibility to accommodate
as wide a range of customer needs as possible.
While all frames do indeed serve the same basic purpose – to house the switcher “building block”
components and provide the system infrastructure – component layout, internal signal routing through
backplanes and mid-planes and frame-specific power supply components vary greatly between the
frames. For this reason each frame type in the Cheetah family has its own Technical Manual Volume.
All frame-specific data such as the items just mentioned plus connector locations, pin-outs and other
pertinent information peculiar to the 864XR frame is contained in this Technical Manual.
Using the 864 XR frame and the Cheetah 144X144 Matrix CCA a routing switcher with the capacity of
up to 864 inputs and 864 outputs can be configured in a single 41 rack unit (RU) frame. Table 2-1
indicates the maximum number of each core component type that can be installed in the 864XR frame.
Figure 2-1 is a front view of the chassis layout with the access door open. Figure 2-2 is a rear view of
the 864XR frame.
