6.3 Internal connections
As a general rule, all internal electrical and communications connections are made at the factory.
However, if modules have to be moved, for example, and the connections therefore removed, you will
have to re-establish the connections between 1) the Power Unit ASIC and the Driver Board(s) on the
one hand and 2) the Power Unit ASIC and the Optical Cable Adapter Board on the other.
6.3.1 Connections between Power Unit ASIC and Driver Boards
See the figures and tables on the following pages for the correct connection of internal electrical
and communications connections.
NOTE! The minimum optical cable bending radius is 50 mm.
