Chassis Level Codes (Strobes) assign operational parameters to the switcher frame. There are
ten rotary switches, located just above the frame controller card(s), used to set the chassis level
code and other frame operational characteristics. Proper setting positions for these ten switches
are shown in Figure 5-2.

Each Power Supply Backplane provides slots for up to two power supply modules. Located on
the right side of each backplane for power supplies 1 through 8 is an eight position DIP switch
used to assign identity data to the power supply module(s) installed on the backplane.
Removing the power supply module installed on the right-hand side of the backplane allows
access to this DIP switch. There are two 8 position DIP switches located on the backplane for
power supplies 9 and 10. Proper setting positions for each switch section in the DIP package
are shown in Figure 5-3. In this figure, the power supply modules are shown in dotted lines in
order for the switch locations to be visible.

Each Input/Output CCA Backplane provides slots for up to four input or output CCAs. An
eight-position DIP switch, located on the lower right-hand side of each backplane, assigns a
unique identity to each backplane card. Among other functions, this switch setting allows the
controller circuitry to assign the input or output channel number range to each I/O CCA – thus
allowing any I/O card on the rear panel to be “hot swapped” with a card of like type. Proper
setting positions for each switch section in the DIP package are shown in Figure 5-4. I/O
CCAs must be removed from the backplane to gain access to the DIP switch. Figure 5-4
illustrates switch location and card slots on the backplanes with no I/O CCAs installed.

Your 864XR router is equipped with one of two possible model variants of the matrix
backplane module. Regardless of variant, each Matrix CCA Backplane provides slots for up to
four 128X128 matrix crosspoint CCAs. There are six rotary switches located along the bottom
edge of each backplane. Settings of these switches assign a unique identity to each matrix
backplane and the set of matrix CCAs installed in it. These settings allow the controller
circuitry to assign the input and output channel number range to each matrix backplane and
each matrix CCA. Figure 5-5 shows the location of each of the six switches on each backplane
board, and the location of the backplane model part that identifies the variant. The matrix card
image used in this figure is smaller than actual size to allow the backplane components to be
shown. Setting positions for each switch, for each model variant of the backplane, are provided
in Table 5-1 and listed by individual backplane boards.
