Design Considerations
By the time you are ready to install your equipment and software, you (or someone in your orga-
nization) will have already made most of the system design decisions. In fact, the design
decisions will have been made before the equipment is ordered. The following is a review of the
concepts.
At first release, the CR6400 routers operate in stand-alone mode with an attached (or “captive”)
control panel. The other modes, available to other compact routers, are not available for the
CR6400.
Stand-Alone Router
A single CR6400 router operates in stand-alone mode with an attached (or “captive”) control
panel. A single stand-alone router will work reliably and operation is extremely simple.
The single CR6400 can switch signals according to the type of I/O cards installed in the 4 slots at
the rear of the router. The CR6464-3Gig switches video; the CR6464-AES switches audio.
Stand-Alone Network
A stand-alone network will include 1–4 routers and one CP6464, mounted on one of the routers.

Additional CP6464s could be mounted on the other routers, but they would provide little or
no additional capability.
Each router in the network is considered a level . The levels are numbered and the level numbers
range from 1 to 4. The routers can be switched either independently or simultaneously for
multi-level takes.
 The term level, at this release, means nothing more than a router number.
Rack Mount
The CR6400 routers are designed to mount in a 19” rack. Rack-mounting is not a requirement,
but we assume a 19” rack for the sake of simplicity.
Follow these steps to install a CR6400 router:
1 Set the position of the 16-position rotary switch on the front of the router. (It is not on the
control panel. If the control panel is mounted on the router, you must detach the control
panel from the router to access the rotary switch.)
If you have a single CR6400 router, set the switch to any non-zero position.
If you have more than one CR6400 router, their rotary switches must be set to positions in
the range 1–4. The switch positions for the routers must all be different.
Refer to Levels and IP Addresses in Stand-Alone Networks , on page 18 for information on
how the rotary switch is used.
Use a small slotted screwdriver to turn the rotary switch.
2 If the router is to have a CP6464 control panel, place the panel on the front of the router,
mating the electrical connector on the panel to the electrical connector on the router. The fit
requires only minimal force. Tighten the knurled screws that secure the control panel to the
