8.1.3 Modules
The modules are composed of PCBs 250 mm high and 210 mm wide.
They are connected to the backplane wiring of the XMP1 subrack via
64/96-pin plug connectors. Since all modules have a uniform connector
assignment to the bus line on the backplane, the XMP1 subrack can be
freely equipped.
The only exception is made by the Central Unit (and the redundant Central
Unit). The latter must always be mounted in the extreme right of the
XMP1 subrack. The corresponding openings for LEDs are provided in the
front panel.
Plug connectors F1 and F2 as well as the signal and power supply wiring
are located on the front side of the modules.
