Introduction to Card 

ZXR10 5250 system can be divided into switching control module, power supply module 
and interface module based on the responsibilities they assume. 

4.2.3.1 

Control Card 

Control card is the core component of ZXR10 5250. It mainly implements two functions of 
control module and switch module. 

In ZXR10 5250 system, control switch card is installed in the cassette structure with no 
independent panel. Its related interface and indicator are on the front panel of the system. 
The principle is shown in the following diagram:
