6-4 MTR3000 Backplane: Description
6.1.1.2 Backplane Interface Board Connectors Information
Each connector on the backplane interface board has been assigned a connector designation
number. For rear connectors, the connector number is stamped onto the metal shield covering the
rear of the backplane interface board. Labels for connectors which accept the plug-in modules are
viewable when the front panel is removed. Table 6-1 lists each connector and its assigned
designation number.
Table 6-2 provides a detailed description of all of the backplane interface board signals, arranged in
alphanumeric order.
As shown, each connector Pin is defined by signal name, input or output (with reference to
connector), and the to/from location(s).
