6.0 System Modules

System modules include various adaptors, optical multiplexing cards, optical redundancy cards, power
interface boards, and other types of subassemblies used to build up 907 stacks or special configurations.
Many cards are custom built for unique applications. The most commonly used system modules are shown in
the following sections. Please contact Focal for custom requirements.

907-EURO (Eurocard Adaptor)

Card P/N
Config. Dwg.
The 907-EURO Eurocard adaptor shown in Figure 6-1 is used to add a Model 907 card to a Model 903
system. The 907 Card is typically soldered to J2 via the PC/104 backplane connector and further held in place
with four standoffs. The pins are soldered if 907 expansion cards are used and no pins are soldered if 907
multiplexer motherboards or media converters are used. Soldered combinations are assembled by the factory
only.
Switch S1 is used to enable and disable the use of the Model 903 backplane for data I/O to the 907 card.
When data I/O is disabled, the Model 903 backplane is only used to supply +5 V power and ground, which
supports the use of 907 motherboards and media converters. When data I/O is enabled, the Model 903
backplane provides power and access to 903 backplane data lines, which supports the use of most 907
expansion cards in a data slot on a Model 903 chassis.
