The rear panel RJ-45 Ethernet connectors, illustrated in Figure 3-18, interface the Matrix Frame
Controller CCA(s) and the System Controller CCA(s) mounted in the 864XR chassis to external
system components over a 10 or 100Mb/s TCP/IP network. You will notice there are two connectors
for both Frame Control and System Control, one labeled Slot A and the other labeled Slot B. This
nomenclature identifies which card is communicating through each connector. For example, the rear
panel RJ-45 Connector labeled System Control, Slot A attaches to the system controller CCA installed
in System Controller Slot A of the 864XR chassis, refer to Figure 3-20. Likewise, the rear panel
connector labeled Frame Control, Slot B attaches to the Frame Controller CCA installed in Frame
Controller Slot B, etc. Note that two frame or system controller CCAs may not be present in all
chassis. Two CCAs of each type are used in systems equipped for control system redundancy. In
systems where only one frame or system controller CCA is used, ensure that the Ethernet cable is
attached to the rear panel connector corresponding to the chassis slot in which the card is installed.
Every frame in a Cheetah routing system requires a frame controller and a system controller. The
network connectors allow a control network to be installed between PESA components such that, for
example, a system controller CCA installed in an 864XR frame may also communicate with and
control frame controllers in other Cheetah Video Matrix routers or a DRS Audio Router. Likewise,
using the Frame Control Ethernet Connectors allows the frame controller CCA in the 864XR chassis
to communicate with a system controller CCA installed in another Cheetah router, or a stand-alone
rack-mount System Controller Chassis.
