The DIP switches and rotary switches on the various backplanes and in the chassis frame are factory set
to assign operational parameters to the system components. The switch settings assign such things as
what channel numbers a bank of input or output cards will service, frame type, number of cooling fans,
etc. Although the switches are set at the factory for every system, a guide to the proper settings for each
switch peculiar to the 864XR Frame is included in Chapter 5 of this manual. This scheme of assigning
identification to the backplane and interface ports allows full interchangeability between like CCAs in
the system.
In every frame variation the input cards and the output cards are loaded through the rear panel card
chassis into mating connectors located on an I/O backplane. Each card chassis is configured using I/O
backplanes with four cards installed to each. All slots may or may not be used in a particular system
dependent on the number of input and output channels and whether or not the output cards are fitted
with option cards. When option cards are used, each output card will occupy two slots in the card
chassis. In a typical Cheetah system, the input cards and output cards will be co-resident in the card
chassis. Be aware that although input cards and output cards can be co-resident in the card chassis, they
CAN NOT be co-resident on the same backplane. Each I/O backplane in the chassis is designated as
either an input or an output backplane.
