CLN1202 Station Backplane

BACKPLANE CONNECTORS INFORMATION
Each connector on the backplane has been assigned a connector designation number. For rear connectors, the con-
nector number is stamped into the metal shield covering the rear of the backplane board. Labels for connectors
which accept the plug-in modules are viewable when the front panel is removed. Table 1 lists each connector and
its assigned designation number. Table 2 provides a detailed description of all of the backplane signals, arranged
in alphanumeric order. NOTE: An asterisk (*) indicates an active low signal.
Figure 3 provides pin-out information for all non-Eurocard connectors located on the rear side of the backplane
board. For the 96-pin Eurocard connectors, Tables 3 through 7 provide pinout information for each of these con-
nectors. As shown, each connector pin is defined by signal name, input or output (with reference to connector),
and the to/from location(s).
