Figure 1-10 Schematic Diagram for Back Panel of OM200 Dual-Chassis System

OM200 dual-chassis system consists of a main chassis and an expansion chassis. Seen from the front,
it is different from the screen-printed mark: main chassis printed with "OM200-MAIN" mark and
expansion chassis printed with "OM200-EXT" mark. Seen from the back, the difference is obvious:
expansion chassis does not have status indicator, USB interface, CON interface and two Ethernet
interfaces. The main and expansion chassises have their own independent power supply and cooling
system, which are connected by a 36-core flat cable to form a logical integrated system.
To ensure the reliable communications between two chassises and reduce EMI interference, the
communication cable for connecting two chassises should be short. OM200 dual-chassis system must
be placed adjacently in installation (users who plan to expand capacity should reserve a space for
expansion chassis during the initial installation of single chassis), the up or lower position is not
strictly required for the chassises.
