Connections between Power Unit ASIC and the Control Unit

The communication connections between the liquid-cooled drive power unit and the control unit (see Page 6-1) can be established using either the conventional round cable (standard in chassis CH3, CH4 and CH5) or optical cable (all chassis). Note that for chassis CH61 and larger, only optical cables can be used.

Connections with Round Cable

The communication connection between the drive power unit and the control unit in chassis CH3, CH4 and CH5 are primarily made with conventional round cable and D-connectors at both ends.

Remove the protective cover to reveal the D-connector on the power unit. Connect one end of the communication cable to the D-connector of the power unit and the other end to the control unit. If the Optical Cable Adapter Board (see below) sits on the D-connector of the control unit, you have to remove it first. See Figure 4-18below.

Connections with Optical Cable

If optical cables are used to link the power unit and the control board, a special Optical Cable Adapter Board connected to the control board D-connector must be used. To connect the optical cables to the power unit, you will have to remove the protective cover first. See Figure 4-18. Connect the optical cables as shown in Figure 4-19. Also see Page 4-10, Control Unit Mounting Box. The maximum length of the optical cable is 33 feet (10m).
