Chassis Configurations3.2.2. Cable HarnessThe chassis require specific cable harness assemblies to be installed based on the PCBconfiguration. Ribbon cables are required for the main system bus. This is a 60-wayribbon cable, which connects the main system boards together. The number of positionsor slots required for this cable is dependant upon the number of main boards beinginstalled. The boards connected by this main bus are CSEX, VRD, CPU <strong>II</strong>, IOB andVSC. The VRD PCB takes 2 slots.Cable harnesses are also required to connect the PCB edge connectors to the plugcouplers on the rear cover of the chassis. These cables are detailed below. There are21 available plug coupler locations on the rear panel and four 60 way ribbon cablelocations. The blank plates listed below are used to cover the unused locations. Also,there are several variations of output and input cables to provide a variety ofarrangements of plug couplers and board configurations.P2511G, Rev. Jan/06 3–4 ALSTOM Signaling Inc
